    105 Tips mengemudi hemat BBM (Ecodriving)

    105 Tips mengemudi hemat BBM & penggunaan BBM secara bijak.


    Getting started ...

    1) Drive less

    The best way to reduce fuel use is to drive less:

    a) Live closer to work;
    b) carpool;
    c) bicycle;
    d) walk;
    e) take public transit



    2) Park and ride (bicycle)

    If part of your commute is not biker friendly, travel to a point
    that is and then bike the rest of the way.

    The "park and ride" concept can also be applied to carpooling and
    mixed private/public transit travel.



    3) Attend a driving clinic

    Hybrid owners groups are popping up in cities around the world -
    and non-hybrid owners are often welcome to attend regular meetings.
    Fuel efficient driving techniques are commonly discussed, and clinics
    are sometimes offered by experienced members.



    4) Clean junk from your trunk

    The additional weight you carry in your vehicle doesn't ride for
    free. It takes energy to move it around. Removing unnecessary stuff
    from your vehicle saves fuel.



    5) Let the most efficient driver drive

    More than one licenced driver in the vehicle? Let the most
    efficient driver drive! And take the opportunity to learn from his/her
    wisdom.



    6) Join a fuel economy forum

    Join an outstanding forum to learn ways to increase your fuel
    economy by talking to others who share your enthusiasm and goals.



    7) Remove unused roof racks

    If your vehicle come with a roof rack and you don't use it, remove
    it. Same holds true for bike racks. Doing so will reduce aerodynamic
    drag, resulting in better fuel economy.



    8) Check tire inflation regularly

    Make sure that your tire pressures are, at minimum, set to
    manufacturer specifications. The higher the pressure, the less rolling
    resistance.

    Remember that pressure is affected by ambient temperature. As
    temperature drops, so does your tire pressure, so keep track as the
    seasons change.



    9) Track your fuel consumption

    One of the first steps in improving efficiency is tracking fuel
    consumption.

    Get in the habit of saving all your fuel receipts, recording
    distance travelled and fuel economy (MPG). Keep a small notebook to
    record trip type and new techniques employed to monitor your progress.

    While the slower pace of tank-to-tank feedback isn't ideal for
    feedback on driving technique, recording and montoring your "big
    picture" progress is great motivation.

    See the Ecomodder Blog for more information on tracking fuel
    consumption.



    10) Use a fuel consumption display

    Feedback is absolutely critical to improving driving habits.

    Tank-to-tank monitoring of your consumption is not good enough.
    You need instrumentation that lets you reset the readout at will so
    you can track individual trips, or even portions of trips you
    regularly travel.

    Options for vehicles without factory installed fuel economy
    computers include the ScanGauge and SuperMID. Even the venerable
    vacuum gauge can help you improve efficiency when driving with load /
    target driving.




    Route selection and trip timing ...

    11) Take the road less traveled

    Generally speaking, if you have the option of choosing lightly
    traveled roads over busier ones, you give yourself more flexibility to
    employ a wider range of fuel saving techniques than if you are
    surrounded by other vehicles.

    You may even find that a somewhat longer, lightly traveled route
    may result in lower overall amount of fuel used than the shorter,
    busier route.



    12) Leave early and don't rush

    The enemy of efficient driving is finding yourself in a rush.
    Leave for your destination a little early so you don't feel pressure
    to drive faster, brake later and otherwise fall back into bad habits.

    Driving efficiently can be much more relaxing than the typical
    person's driving style, but you need to allow a bit of extra time.



    13) Crosswind barrier

    Headwinds aren't the only winds that increase fuel consumption -
    cross winds can have a large negative effect as well. In crosswind
    conditions, choosing a route with a barrier (trees or buildings) along
    the edge will save fuel compared to a road in the open.



    14) The 'corridor effect'

    All else being equal, traveling at a constant speed on a freeway
    within a flow of traffic (in the same direction) is more efficient
    than going the same speed in isolation. The reason is aerodynamic: a
    flow of traffic generates a localized wind current in the direction of
    travel. You will benefit from this artificial breeze.



    15) Note your transition points

    If you regularly travel the same roads, make a conscious effort to
    note (memorize) the points along the way where transitions occur that
    maximize efficiency.

    EG. memorize where you can initiate a coast to just make it to the
    next stop sign. Or note at what speed you can crest a hill so you're
    traveling just fast enough for the next transition after the descent.



    16) Time your gas station trips

    Plan to refuel your car during off-peak times to avoid lines and
    excessive idling.



    17) Avoid drive-thrus

    Avoid drive thru windows. They lead to excessive idling.



    18) Lane of least resistance

    In multi-lane traffic, choose the "lane of least resistance" to
    avoid unneccessary and unpredictable braking/changes in speed.

    EG. avoid lanes where buses are starting and stopping, or cars may
    be braking unpredictably to turn into driveways/parking lot entrances.



    19) Avoid stops at bottom of hills

    Avoid roads with stops at the bottom of hills (which force you to
    brake and waste the kinetic energy you just gained going downhill).



    20) Take advantage of the wind

    If possible, time trips to take advantage of strong tailwinds.
    Avoid setting out into strong headwinds/crosswinds.



    21) Choose smooth road surfaces

    Choose a route with a smooth, paved/concrete surface over gravel
    or rough, broken roads, all else being equal. Smoother surfaces offer
    reduced rolling resistance.



    22) Avoid bad weather

    Avoid driving in inclement weather if possible, as rain/snow/slush
    can dramatically increase rolling resistance.

    The exception to this rule may be when high winds (tailwinds) can
    be used to your advantage.



    23) Avoid peak traffic

    If you have the option, avoid travel during peak traffic times.
    With the roads full of other drivers, you have fewer options for using
    driving techniques that the herd doesn't typically use or tolerate
    (e.g. reduced highway speeds, drawn out coasting up to stop signs, etc).



    24) Drive when it's warm out

    If you have the flexibility, time your trips to coincide with warm
    temperatures (ie. middle of the day) rather than cold (night/early
    morning).

    Cold tires and drivetrain experience more rolling and mechanical
    resistance, and a cold engine is less efficient.




    Sub/urban driving ...

    25) Conserve momentum: stop sign 'stop and crawl'

    When multiple vehicles ahead of you are progressing through a stop
    sign (or a right turn at a red light), this represents a mini 'stop
    and crawl' situation normally found in a bumper to bumper traffic jam.

    Time your approach, to arrive at the stop sign as the last car
    ahead is departing.



    26) Conserve momentum: take a shortcut

    Sometimes options exist to go through corner parking lots, side
    streets, or alleyways to get around having to come to a stop at an
    intersection or behind another vehicle.

    Of course the utmost care must be taken in parking lots as they
    present their own risks (pedestrians, vehicles reversing from parking
    spots, etc.)

    Also, cutting through corner parking lots may be illegal in some
    areas.



    27) Combining errands: do the longest leg first

    When combining multiple trips into one journey, go to your
    farthest destination first, and work your way back. This ensures the
    vehicle is warmed up as much as possible before subjecting it to
    multiple starts and stops.



    28) Minimize idling when stopped

    If you're going to be stopped for more than a few seconds, shift
    to neutral and shut off your engine. This is one of the main reasons
    hybrid vehicles get such good fuel economy in urban driving.

    Caveat 1: this assumes your vehicle is in good tune and will
    re-start immediately, every time.

    Caveat 2: if you're a defensive driver, you're habitually
    evaluating the risk of a rear crash when slowing and when stopped.
    Obviously you will want to leave your engine on in those circumstances
    (for a quick rear crash avoidance manoeuver).



    29) Traffic light timing - stale 'green', no pedestrian signal

    In the absense of any other indication about how stale the light
    is (eg. if there's no pedestrian signal or waiting cross traffic),
    assume that the green light ahead is about to change. Adjust your
    approach speed accordingly (IF traffic permits - ie. you don't hold
    anyone up) to avoid a full-on brake application should the light change.



    30) Combine errands

    Avoid very short trips. If you have multiple stops, plan them to
    do all on the same trip. Fuel economy is enhanced once the engine is
    warmed up, so a longer "chain" of errands will result in better fuel
    economy than multiple short ones, particularly in cold weather.



    31) Traffic light timing - red lights with sensors

    When approaching a red light, slow down early if there's a car in
    front of you that can trip the sensor so you may not have to come to a
    complete stop.

    CleanMPG.com cleverly nicnamed this technique "rabbit timing"



    32) Traffic light timing - 'stale' green

    When approaching an intersection with a green light you can watch
    the pedestrian signal crossing light to help determine when it will
    turn yellow.




    Highway driving ...

    33) Lights on for safety; lights off for MPG

    In certain driving environments / conditions, the use of daytime
    running lights (DRLs) or manually switching on headlights during the
    day increases safety.

    Depending on the vehicle, power demands of the lighting system
    ranges from a few watts to well over 100 watts, all of which is
    ultimately powered by gasoline. In the US, where DRL implentation is
    voluntary, automakers have an exemption from CAFE testing which
    permits vehicles' fuel economy to be tested with the lights switched off.

    Switching off DRLs where their safety contribution is minimal (eg.
    driving on a divided, controlled access highway) will save a small
    amount of fuel.



    34) Find/adopt a 'blocker' for slower freeway speeds

    Some people are uncomfortable driving at speeds less than the
    average flow of traffic on multi-lane freeways.

    One solution is to find another vehicle going the speed you want
    to travel (large, conspicuous vehicles work particularly well) and
    drive either ahead of or behind it. (Note: this is not a suggestion to
    draft.)



    35) Close the sunroof at higher speeds

    Some sunroof styles are better than others. The worst offenders
    are the kind which tilt and slide to the outside, on top of the roof.
    When open, these "roof-top spoilers" can significantly increase
    aerodynamic drag.



    36) Drafting: cross wind

    In rare circumstances, it is possible to effectively "draft" a
    larger vehicle in cross wind conditions without following directly
    behind it. When cross wind conditions cause the low pressure area
    trailing the lead vehicle to extend into adjacent lanes, you can take
    advantage of reduced drag legally and with reduced risk.

    Note: 1) this is not describing side-by-side driving, but
    postioning that is offset to the rear. 2) While visibility directly
    ahead is increased, a significant chunk of the driving picture may
    still be blocked depending on the size of the lead vehicle.



    37) Drafting: close behind (not recommended!)

    1) At highway speeds there's no doubt that driving close behind a
    large vehicle dramatically reduces fuel consumption. 2) It's a stupid
    thing to do.

    It's not recommended for many reasons, not the least of which is
    that it's illegal in most areas, and doing so sacrifices the
    foundation of safe and defensive driving: your ability to see well ahead.



    38) Windows up

    Drive with windows up at higher speeds to minimize aerodynamic
    drag. Use flow-through ventilation if possible.



    39) Reduce speed

    Aerodynamic drag increases exponentially with speed, so reduce
    highway cruising speed as much as practical and safe.

    Generally, a vehicle's most efficient speed is just after its
    highest gear has engaged.

    See the Ecomodder Blog for more information on tracking fuel
    consumption.



    40) Constant throttle position cruising

    Once up to speed, pick a throttle position and hold it.

    Advantages: more efficient than using the cruise control (which
    varies throttle position frequently and wastes fuel on hills).

    Disadvantages: less efficient than "driving with load" (DWL) /
    "target driving" (where the throttle is eased on inclines).



    41) Cruise control - when to use it

    Set the cruise control if you're the type of driver whose speed
    creeps up higher and higher the longer you're on the road, or if you
    have difficulty holding a steady speed (it wanders up and down).

    But realize that cruise control is just a band aid for those
    behaviours. Generally it's less efficient than constant throttle
    driving, and much less efficient than "driving with load" / "target
    driving".



    42) Cruise control - when not to use it

    Only use cruise control on flat roads. On hilly roads, cruise
    responds to changes in grade - by feeding in more throttle on the
    uphill and releasing on the descent - in the exact opposite way an
    efficient driver would.




    Braking tips ...

    43) The most efficient way to slow down

    When you *have* to slow down, here's an approximate heirarchy of
    methods, from best to worst.

    1) coasting in neutral, engine off (ie. roll to a stop);
    2) coasting in neutral, engine idling;
    3) regenerative coasting (hybrid vehicles)
    4) regenerative braking (hybrid vehicles)
    5) coasting in "deceleration fuel cut-off" mode (in gear, above a
    certain engine RPM)
    6) conventional friction braking (non-hybrid or hybrid)

    Choosing the right method depends on traffic conditions (following
    vehicles) and how quickly you need to stop.



    44) Conserve momentum: avoid stopping

    Avoid coming to a complete stop whenever possible (and when safe
    and legal of course). It takes much less energy to accelerate a
    vehicle when it's already traveling just a few kilometers per hour
    than it does from a complete stop.



    45) Hybrids: minimize regen braking

    While regenerative braking in hybrid vehicles - capturing braking
    energy into the battery - is more efficient than braking with
    conventional friction brakes, it's still not as efficient as 'driving
    without brakes' (DWB).

    So even if you drive a hybrid, you'll get better economy when you
    minimize use of the brake pedal.



    46) "Drive without brakes" (DWB)

    Minimize use of the brake pedal. Each time you press it, you're
    effectively converting gasoline into brake dust and heat.

    Driving as if you have no brakes will cause you to do two things:
    1) reduces 'excessive' acceleration, and, 2) extends the amount of
    time you spend coasting down to stops and turns.

    Obviously you have to balance use of this technique against
    traffic conditions so as not to adversely affect other drivers.

    See the Ecomodder Blog for more information on DWB.




    Advanced techniques ...

    47) Drive shoeless

    Some [cencored] hypermilers drive in sock or bare feet so they can
    modulate the accelerator to the finest degree (particularly important
    when "driving with load" / "target MPG driving" at cruise.

    It shouldn't be that surprising. Race car drivers typically wear
    extremely thin-sole boots for similar reasons: for the highest level
    of tactile feedback from the vehicle, and to better finesse the pedals.



    48) Conserve momentum: brake hard

    It sounds like a contradiction, but there are rare times when
    braking hard can save fuel compared to coasting or light braking: it's
    a "damage control" technique when faced with an
    unpredictable/unanticipated stop or slow down ahead and not a lot of
    space.

    An example: approaching a fresh red traffic light that had no
    other indicators to predict the change (no pedestrian signal and no
    cars waiting on the cross street). If you brake lightly/moderately,
    you will cover the entire distance to the intersection and have no
    option but coming to a full stop.

    But if you brake quite hard initially, you can potentially scrub
    enough speed and buy enough time to coast the remaining distance to
    the intersection at a low speed. With judgment and some luck, you'll
    arrive at a fresh green light and avoid a full stop.

    Obviously, rapid deceleration isn't a safe option if there is
    following traffic.



    49) Make fuel economy a game/challenge

    Competing against yourself (or others) to get the best possible
    fuel economy can do wonders for increasing motivation to learn more,
    refine your skills, and try harder.

    Several web sites like EcoModder.com permit you to track and
    compare your fuel economy against other drivers, and some organize
    informal fuel economy challenges.

    Hybrid festivals (e.g. hybridfest.com, greengrandprix.com)
    periodically run fuel efficiency rallies where you can hone your
    skills in competition with others in real time.



    50) Use the 'racing line'

    Knowing how to pick the "racing line" through a corner, when safe,
    can help to preserve momentum. Generally, the racing line is the path
    through a turn with the largest possible radius. It may permit a
    higher speed with more comfort (less body roll and g-forces), and less
    tire scrub.

    Note this isn't advocating high speed turns, where the cost of
    increased tire wear may outstrip fuel savings. Even at low speeds,
    choosing the "racing line" has benefits.



    51) Encourage a pass: the fake turn

    Drivers who travel below the normal flow of traffic should
    facilitate drivers approaching from behind to go past safely, with a
    minimum of interruption.

    "Faking" a turn by signalling and moving into a turning lane (even
    though you intend to continue straight on) is one option.

    Note: judgment and care is demanded so you don't mislead any
    driver into making an unwanted move as a result of your
    "miscommunication". You must be prepared to actually make the turn if
    your actions create a situation that would make it the safest option.



    52) Encourage a pass: hug right

    Drivers who travel below the normal flow of traffic should
    facilitate drivers approaching from behind to go past, rather than
    force them to slow down.

    One method of gaining the attention of the driver behind is to
    move your vehicle very obviously to the extreme right of the lane
    you're traveling in when it's safe for the following vehicle to pass.

    Adding a turn signal to the move or the 4-way flashers may be even
    more effective.

    Of course, pulling completely off the roadway onto the shoulder to
    let following traffic by is also worthwhile, if you have the option.



    53) Hill tactic: don't waste potential energy

    When facing a red traffic light, or some other predictable
    stop/start situation at the bottom of a hill, you're better off
    stopping near the top before you've accelerated to full speed. Wait,
    and time your release to make it through on green, and you avoid
    turning your potential energy into brake dust and heat. (Also known as
    'smart braking'.)



    54) Engine off coasting

    Engine-off coasting (EOC) is one of the largest contributors to
    increased efficiency of hybrid vehicles, many of which automatically
    shut down the engine when the accelerator is released and the vehicle
    is coasting.

    EOC can be accomplished in non-hybrids as well simply by shifting
    to neutral and switching the key from "Run" to "Acc" (being careful
    not to switch to "Off" and cause the steering to lock). As soon as the
    engine stops, return the key to the "Run" position so the odometer
    continues to count distance traveled and you're ready for a re-start.

    This technique is best suited to cars with manual steering and
    manual transmissions. (Dramatically increased steering effort may be
    required in some cars with power assist. Also, most vehicles with
    automatic transmissions are not designed to travel with the engine
    shut off; the transmission may be damaged).

    In non-hybrids, EOC is considered an advanced technique and should
    not be attempted until the skill developed away from traffic. In
    addition, coasting with the engine off is illegal in some areas.



    55) Drive with load (DWL)

    AKA "target driving". Put most simply, this technique is
    accomplished by choosing a "target" rate of fuel consumption and
    ensuring you don't fall below it on hills (or in very strong winds, or
    any conditions which cause load to vary for a given speed).

    In other words, you will back off the accelerator and lose speed
    (possibly also downshifting) as you climb, and gain that speed back on
    the descent.

    It's far more efficient than pressing the accelerator more and
    more to maintain speed on the way up a hill and then releasing it down
    the other side.

    DWL is how an efficiency minded person can greatly outperform
    cruise control in hilly terrain.

    Obviously the ability to use this technique without adversely
    affecting other drivers depends on the traffic situation.

    As well, fuel economy instrumentation is required to DWL/target
    drive to the maximum extent, though it can also be done using a vacuum
    gauge, and to a much lesser extent by the seat of the pants.



    56) Heavy traffic: play the accordion

    If faced with worst-case "stop & crawl" traffic conditions, leave
    as much space ahead of you as possible and continually "accordion"
    that space to keep your vehicle moving near a constant speed while the
    cars in front of you stop & start.

    Yes, some people will cut into the space you create ahead of you.
    Deal with it.

    Note that this may aggravate following drivers who can't absorb
    the big picture, and that must be taken into account.



    57) Pulse and glide (P&G)

    Use pulse and glide (or "burn and coast") rather than maintaining
    a constant speed, where practical.

    Pulse and glide explained



    58) Push it - 1

    If you only have to move your car a very short distance - eg. out
    of the garage - consider rolling it rather than starting it up to move
    it.



    59) Push it - 2

    If you're starting out on an incline, give your car a shove to get
    it rolling as far as possible before starting the engine.




    Parking (and departing) ...

    60) Start up: wait for the opportunity to move

    Don't start the engine until there's actually an opportunity to
    start driving: eg. a gap in traffic when exiting a driveway or parking
    space.

    You can plan even further ahead: don't turn the key until you know
    you can time the next traffic light down the street.



    61) Parking tactics: orbit to bleed momentum

    If you find you have too much momentum after reaching your
    preferred parking spot, continue coasting further down the row or
    "orbiting" a spot until you can roll to a stop in position without
    touching the brakes.

    (The extent to which you might continue 'orbiting' depends on
    whether your engine is on/off and whether you're driving a manual or
    automatic. Also, it depends on traffic in the lot, obviously.)



    62) Parking tactics: gravity assist

    Slopes can be useful in manoeuvering into a parking place. One
    which I regularly back into (it can't be driven through) has a small
    slope across from it. I kill the engine approaching the slope, and
    engine-off coast backwards into the spot.

    Gravity can be a hindrance in parking as well. Avoid driving down
    into a parking "hole" which you must drive out of later. Even if you
    EOC into the hole, you'll face a net efficiency loss when you drive
    your cold vehicle up and out later.



    63) Parking tactics: avoid parallel parking

    For on-street parking, the better spot is one with enough room to
    pull in/out rather than multiple reverse/forward manoeuvering
    (parallel parking).



    64) Parking tactics: reverse in

    If you have no pull-through spots to choose from, reverse in when
    arriving, instead of driving in when warm and backing out/turning
    around when the vehicle is cold and fuel economy is at its worst.

    Also note that reversing into a flow of traffic is riskier (and
    therefore much slower and less efficient) because you may not have a
    clear view until your vehicle's back end is well out of the space.



    65) Parking tactics: pick the periphery

    Choosing a spot in the "periphery" of a busy lot will be more
    efficient than navigating the rows of traffic/pedestrians to get as
    close as possible to the building or destination.



    66) Parking tactics: pull-through spot

    Drive into a "pull through" spot, rather than a spot that requires
    reverse/forward manoeuvering.



    67) Start up: not until you're adjusted

    Don't start the vehicle until you're settled in: seat, seatbelt &
    mirrors adjusted; passengers settled in as well.



    68) Multiple vehicles: choose the one that's warmed up

    In a multi-vehicle household, if you have the choice of using
    similar vehicles, choose the one that was driven most recently if it's
    still warm.



    69) Multiple vehicles: choose the most efficient one in the 'fleet'

    If you have a multi-vehicle household or workplace, choose the
    most efficient vehicle from the fleet that will accomplish the task at
    hand.




    Transmission tips ...

    70) Automatic transmission: key off, then Park

    Save a few drops of fuel by modifying your shutdown procedure:
    when parking, turn off the key *before* shifting to Park and setting
    the parking brake.



    71) Manual transmission: cruise in high gear

    When cruising at a constant speed, shift to the highest gear you
    can use without lugging the engine.



    72) Automatic transmission: highest gear/lowest RPM for posted speed

    When cruising, drive the the speed that allows the lowest RPM for
    the speed zone you are in.

    EG. if the posted speed is 30 and your car shifts into 3rd at 35,
    you may be able to achieve the 3rd gear shift, then reduce and hold 30
    without causing a downshift.



    73) Automatic transmission: torque converter (TC) lockup

    Drive at the speed that allows the TC (torque converter) to lock
    up. This is often around 40-45 mph. Speeds just above this typically
    return the higest cruising fuel economy.



    74) Automatic transmission: neutral when stopped

    Shift automatic transmissions to neutral when stopped (assuming
    you're going to leave the engine running). Remaining in drive wastes
    fuel as the engine continues to try to creep the car forward while
    being held back by the brakes.



    75) Automatic transmission: upshift coaxing

    Some automatic transmissions can be coaxed to upshift sooner when
    accelerating by briefly releasing some throttle pressure, then
    re-applying to continue accelerating.



    76) Automatic transmission: use OD (overdrive)

    If your transmission has an "OD" (overdrive) button or position,
    leave it engaged to ensure the transmission will shift into its
    highest gear as soon as possible.



    77) Automatic transmission: use economy mode

    If your automatic transmission has a "power/economy" button, leave
    it in economy mode. This usually results in earlier upshifts and later
    downshifts, saving fuel.




    Winter / foul weather ...

    78) Wait for the snow plow

    Driving through fresh snow increases rolling resistance moderately
    to dramatically, depending on the depth/type of snow. Better fuel
    economy will result when you wait for the plows (or for other vehicles
    to pack the snow down) before setting out.

    Similarly, getting stranded in a ditch or snow drift because you
    set out in bad weather is a surefire way to waste fuel if you need to
    idle the car to stay warm while waiting for help.



    79) Winter: avoid wheel spin on ice/snow

    If you drive in ice/snow, avoid wheelspin when traction is low.
    Changing to dedicated snow/ice tires that offer better traction may
    save fuel.

    Wheelspin is especially inefficient if your vehicle is equipped
    with brake assisted traction control.



    80) Follow the leader in rain or snow

    In weather conditions that leave a lot of precipitation on the
    road - heavy rain or snow - drive in the tiretracks of the vehicle in
    front to reduce rolling resistance.

    An exception to this tip may be on "rutted" surfaces where water
    tends to pool in the ruts. In that case, driving on the ridges between
    the ruts offers less resistance.



    81) Winter: clean off snow & ice

    Completely clear snow & ice off your vehicle before driving. It
    will minimize your use of energy hungry accessories (defrosters),
    remove an aerodynamic penalty (increased frontal area), and reduce
    weight (a layer of ice and snow over an entire vehicle can weigh a
    surprising amount).



    82) Winter parking: clean out the garage

    If you have one, clean out your garage so you can park your car
    inside during the cold months of the year. The faster warm up will
    return better fuel economy.



    83) Winter: use heated parking

    If you've got the choice, heated parking will improve fuel
    economy. The potential downside is that it may increase the rate of
    corrosion if you drive where roads are salted.



    84) Avoid heater use until the engine has reached operating temperature

    Engines runs rich until a minimum temperature threshold is
    reached. Running the heater blower before that has happened will
    slightly increase warm-up time and increase fuel consumption.



    85) Avoid 'warm up' idling

    Don't idle your engine to warm it on a cold day. An idling engine
    gets zero miles per gallon.

    Start to drive - under light loads - as soon as the engine is
    running smoothly (usually immediately). It's a more efficient way to
    warm the engine and entire drivetrain, including tires.




    Hot weather ...

    86) Cycle the A/C if you have to use it

    If you have to use the air conditioner, set the air flow to
    recirculate and manually turn the A/C on and off as needed. For
    greater efficiency, switch it on when under light engine loads or
    deceleration fuel cut off and off when under moderate/heavy loads.
    (Note: some newer vehicles do this automatically.)



    87) Summer: park in the shade

    Parking in the shade will keep the inside of your vehicle cooler,
    which can help you minimize use of air conditioning.



    88) Use a beaded seat cover

    They work surprisingly well as an alternative to (or defer the use
    of) air conditioning, by letting air flow behind & beneath you. They
    keep you from sticking to your seat, and your clothes from sticking to
    you.

    Other non-A/C options include ice vests and DIY ice water A/C units.



    89) Minimize air conditioning use

    Air conditioning requires a lot of power. Use it sparingly.

    Driving at city speeds, you'll save fuel by using your flow
    through vents and opening windows.

    At highway speeds, whether A/C is more or less efficient than
    opening windows will depend on the speed, your vehicle's aerodynamics
    and A/C design.



    90) Trip timing: avoid the hottest times of day to reduce A/C use

    If you live where the weather is very hot, avoid driving if
    possible during the peak temperatures of the day when use of the air
    conditioner is "required."




    Just generally good driving tips ...

    91) Maintain a space cushion

    When driving on a multi-lane roadway, try to maintain a "space
    cushion" around you.

    IE. avoid driving for any length of time beside a vehicle in the
    next lane. The more options you leave open for making a prompt lane
    change if one is needed, the safer and more efficient you'll be (if it
    means avoiding an unnecessary slowdown).



    92) Maintain appropriate following distance

    Avoid driving so close behind another vehicle that you are forced
    to *immediately* brake if it begins slowing down. Important at all
    times, but particularly in sub/urban driving where traffic changes
    speed more often.

    Leave enough space that you have time to choose other options
    (perhaps a lane change).

    In addition, the greater your following distance, the better your
    forward visibility will be, which enables you to look well ahead and
    anticipate changes in the driving environment.



    93) Be smooth

    Smooth use of the accelerator, steering, transmission and brakes
    is not only more comfortable for you and your passengers, it's also a
    little more efficient (less scrubbing of tires, energy lost through
    suspension movement). It's also better for the longevity of the
    vehicle and in general a sign of a skilled driver.



    94) Use your horn defensively

    Defensive drivers will tap their horns to ensure they have the
    attention of other motorists or pedestrians in close quarters and
    potentially risky situations.

    Being proactive will save fuel if it means you can avoid having to
    brake or stop unnecessarily.



    95) Look well ahead & anticipate

    Your ability to drive efficiently depends on being able to
    anticipate changes in the driving environment. The way to do this is
    by constantly scanning well ahead in your intended path.

    In city driving you should know what's happening at least 10-15
    seconds ahead. On the freeway, at least 30 seconds visual lead time is
    appropriate.



    96) Drive the posted speed

    Drive the posted speed limit or the minimum allowed, when safe to
    do so.




    Miscellaneous ...

    97) Don't keep up with the Joneses

    It easy to be competitive when driving. Resist knee-jerk
    retaliation to other drivers' aggressive actions. Don't let other
    drivers lead you astray from your driving style.



    98) Minimize use of low range

    Many 4 wheel drive / AWD vehicles also come with high and low
    transmission ranges. Low range increases engine RPM and fuel
    consumption for a given gear/road speed combination compared to high.



    99) Minimize use of 4 wheel drive

    The added friction of drive components in four wheel drive mode
    increases fuel consumption, especially when the center differential is
    locked and the vehicle is turning.



    100) If you have to carry items outside the vehicle...

    Carry them on the back of the vehicle, instead of on the roof.
    Long, skinny items can even be carried beneath some vehicles (with
    ample ground clearance).

    This is more important the faster and further you intend to go.



    101) Minimize accessory loads

    Minimize use of electrical and mechanical accessory loads when
    safe and/or practical (lights, defrost, blower, electric heated seats,
    dvd players/screens, heated mirrors, etc).



    102) Use a block heater

    Pre-warm your engine with an electric block heater. Engines are
    most efficient at full operating temperature, and the block heater
    helps it get there sooner. About 2 hours is the maximum time needed to
    pre-warm a small engine.



    103) Drive like you ride a bike

    For you cyclists looking for a way to wrap your head around the
    subject of efficient motoring: drive like you bike.

    Meaning, if you think about spending energy as wisely in your car
    as you do when you ride, you should automatically become aware of
    several of the major tips on this list, such as:

    a) Ensuring your tires are properly inflated & vehicle is in good
    mechanical condition, for reduced rolling & mechanical resistance.

    b) Smart braking: you'll spend more distance coasting up to stops
    (you don't pedal madly towards stop signs and then jam on the binders,
    do you?)

    c) You'll "drive with load" on hills (you don't usually power up
    hills trying to maintain your previous cruising speed, do you?)

    d) You'll reduce speed (because cyclists are highly attuned to the
    relationship between aerodynamic drag and the energy consumed to
    travel at high speed).



    104) Avoid towing

    Trailer towing delivers the triple whammy of increased weight,
    higher aerodynamic drag, and a third (or fourth) set of tires for more
    rolling resistance.

    Carry loads in the vehicle if possible.

    If not, minimize towing speeds and adjust your technique to
    account for the extra momentum the trailer and its load will add.



    105) Listen to slower music

    Leave the speed metal at home. Fast paced music can make a driver
    more impatient, more agressive and likely to speed. At the same time,
    slower paced music is more relaxing and tends to promote a more
    sensible driving style while also reducing stress.
