Aggressive driving (speeding, rapid acceleration and
braking) (jack-rabbit starts) wastes gas. It can lower your gas mileage by 40
percent at highway speeds and by 5 percent around town. Sensible driving is
also safer for you and others, so you may save more than gas money. Tests show that
"jackrabbit" starts and hard breaking reduces travel time by only
four percent, while toxic emissions were more than five times higher. The
proper way is to accelerate slowly and smoothly, then get into high gear as
quickly as possible. Along with that, you should not rest your foot on the
clutch or brake pedal as it will cause overheating and fuel wastage. In city
driving, nearly 50% of the energy needed to power your car goes to
acceleration.
Idling gets 0 miles per gallon. Cars with
larger engines typically waste more gas at idle than do cars with smaller
engines. Avoid
idling your vehicle, in both summer and winter. Idling wastes fuel,
gets you nowhere and produces unnecessary greenhouse gases. If you're going
to be stopped for more than 10 seconds, except in traffic, turn off the
engine. In winter, don't idle a cold engine for more than 30 seconds before
driving away. Make
sure your tires are properly inflated Make sure your tires are properly
inflated to prevent increased
rolling resistance. Check tire
pressure at least once a month, when the tires are 'cold' (i.e. when the
vehicle has not been driven for at least three hours or for more than 2km).
Start by checking tire pressures in your driveway. Note any tire that is
underinflated, and then drive to the nearest gas station to add air. Check
tire pressures again at the station, and inflate the low tires to the same
level as the others (these will likely have higher pressure than they did in
the driveway, since the tires have heated up.) Radial tires can be under
inflated yet still look normal. Always use your own tire gauge for consistent
results. On average, tires lose about 1 psi per month and 1 psi for every 10
degree drop in temperature. Under-inflated tires can cause fuel consumption
to increase by as much as 6%.
Using cruise control on the highway
helps you maintain a constant speed and, in most cases, will save gas.
Change up through
the gears and into top gear as soon as possible without accelerating harder
than necessary. Driving in a gear lower than you need wastes fuel; so does
letting the engine labor in top gear on hills and corners. Automatic
transmissions will shift up more quickly and smoothly if you ease back
slightly on the accelerator once the car gathers momentum. When you
use overdrive gearing, your car's engine speed goes down. This saves gas and
reduces engine wear. |
Service your vehicle regularly, according to the
manufacturer's instructions. A poorly tuned engine can use up to 50% more fuel
and produces up to 50% more emissions than one that is running properly.

Air filters: Dirty air filters
can also cause your engine to run at less than peak efficiency Regular visual
checks of the air filter will tell you if it needs replacing and your owner's
manual will also recommend appropriate replacement intervals. Clogged filters
can cause up to a 10% increase in fuel consumption. |
Monitor power accessories.
Be sure to
shut off all power-consuming accessories before turning off the ignition. That
way, you decrease engine load the next time you start up. Items that plug into
your vehicle's cigarette lighter, such as TV consoles for mini-vans and SUVs,
can cause the alternator to work harder to provide electrical current. This
adds a load to the engine and added load increases fuel use, decreasing your
gas mileage.
Think "aerodynamic" and
"lightweight".
Reduce
drag. Out on the open highway, keep windows rolled up to reduce drag. Remove
bicycle and ski racks when not in use. Excess weight also uses more fuel.
Remove unnecessary items from inside the vehicle, trunk or truck bed. An extra 100lbs (48 kg) of weight can
increase your fuel bill by 2%.
Cold weather driving?
Use a block
heater when the
winter temperature drops to -20°C or below. A block heater keeps your engine
oil and coolant warm, which makes the vehicle easier to start and can increase
winter fuel consumption by as much as 10 percent. Use a timer to switch on the
block heater one or two hours before you plan to drive.
Plan your trip
whether you are going across town or across the country. Try to combine several errands in one outing, and plan your route to avoid heavy traffic areas, road construction, hilly trerrain, etc. With a little organization, you can group your "town tasks" into fewer trips, saving you time and fuel expense.
by walking to some nearby destinations. It's good for your health and the environment. Approximately 50% of car use is for trips within 3 miles of the home. This distance is within the range for easy biking, so it makes sense to try to use your bike for some of these short hops. You'll be saving fuel and reducing pollution, and you can also save on trips to the gym with this added exercise.
Combining errands into one trip saves you
time and money. Several short trips taken from a cold start can use twice as
much fuel as a longer multipurpose trip covering the same distance when the
engine is warm. Trip planning ensures that traveling is done when the engine is
warmed-up and efficient.
With a little planning, you can avoid
retracing your route and reduce the distance you travel as well. You'll not
only save fuel, but also reduce wear and tear on your car.
Commuting |
|
If you can stagger your work hours to avoid
peak rush hours, you'll spend less time sitting in traffic and consume less
fuel.
If you own more than one vehicle, drive the
one that gets the best gas mileage whenever possible.
Consider telecommuting (working from home)
if your employer permits it.
If possible,
take advantage of carpools and ride-share programs. You can cut your weekly
fuel costs in half and save wear on your car if you take turns driving with
other commuters. Many urban areas allow vehicles with multiple passengers to
use special High Occupancy Vehicle (HOV) lanes.
Consider using public transit if it is
available and convenient for you. The American Public Transit Transportation
Association has links to information about public transportation in your
state.
Traveling |
|
A roof rack or carrier provides additional cargo
space and may allow you to meet your needs with a smaller car. However, a
loaded roof rack can decrease your fuel economy by 5 percent. Reduce
aerodynamic drag and improve your fuel economy by placing items inside the trunk
whenever possible.
Avoid carrying unneeded items, especially
heavy ones. An extra 100 lbs in the trunk reduces a typical car's fuel economy
by 1-2 percent.
