Tips
to Save Gas
(Information from the University of North Texas - Miguel
Garcia-Rubio, Associate Dean of the College of Engineering)
1. Plan ahead and combine as many errands into one
trip as possible.
2. Inflate your tires to the proper setting.
3. Don't speed, and avoid quick acceleration.
4. Avoid excessive idling.
5. Change air and fuel filters periodically.
6. Buy your gas during the coolest part of the day.
7. Tune up your engine.
8. Use the right engine oil.
Green Driving Tips
(Information from American Council for an Energy-Efficient
Economy)
Buying green is just the first step in reducing the environmental
impacts of automobile use. Your choice of vehicle is most important, but how
you drive and how well you maintain your car, van, or light truck will also
make a difference. Consider the following:
•Avoid "jack rabbit" starts and aggressive driving. Flooring
the gas pedal not only wastes gas, it leads to drastically higher pollution
rates. One second of high-powered driving can produce nearly the same volume
of carbon monoxide emissions as a half hour of normal driving.
•Think ahead. Try to anticipate stops and let your vehicle coast down as much
as possible. Avoid the increased pollution, wasted gas, and wear on your brakes
created by accelerating hard and braking hard.
•Follow the speed limit! Driving 75 mph instead of 65 mph will lower your
fuel economy by about 10 percent, and can dramatically increase tailpipe pollution
in many vehicles.
•When possible, plan your trips to avoid rush hour. Stop-and-go driving burns
gas and increases emissions of smog-forming pollutants.
•Combine trips. Warmed-up engines and catalysts generate much less air pollution,
so combining several short trips into one can make a big difference.
•Take a load off. Carrying around an extra 100 pounds reduces fuel economy
by about 1 percent. Take a few moments to unload your cargo area.
•If your vehicle has it, use overdrive gear at cruising speeds. When driving
a manual transmission, shift up as soon as possible. Running in a higher gear
decreases the rpm and will decrease fuel use and engine wear.
•Try using the vents and opening windows to cool off before you turn on the
air conditioner. Air conditioner use increases fuel consumption, increases
NOx emissions in some vehicles, and involves environmentally damaging fluids.
•Unlike many older cars and trucks, modern vehicles don't need to warm up
and they have automatic chokes, so you don't need to step on the gas pedal
before starting the engine.
Maintenance Tips
•Keep your tires properly inflated. Tires should be inflated to the pressure
recommended for your vehicle; this information is often printed inside the
door frame or in your owner's manual. For every 3 pounds below recommended
pressure, fuel economy goes down by about 1 percent. Tires can lose about 1
pound of pressure in a month, so check the air pressure regularly and always
before going on a long trip or carrying heavy loads. Underinflated tires can
also detract from handling, safety, and how long the tires will last.
•Buy low-rolling-resistance (LRR) replacement tires. Switching to a typical
set of replacement tires lowers a vehicle's fuel economy as much as 4 percent.
LRR tires, on the other hand, are specially designed to improve a vehicle's
fuel economy. Most major tire manufacturers now produce LRR models, so when
it comes time to replace your tires, seek out a set of LRRs.
•Check your own fuel economy every few weeks. If you notice it slipping, that
could mean you have a minor problem with the engine or your brakes. Using this
advance warning, you can fix problems before you have a breakdown on the road.
•Get a tune-up. Whether you do it yourself or go to a mechanic, a tune-up
can increase your fuel economy. Follow owner's manual guidelines. Be sure to
check for worn spark plugs, dragging brakes, and low transmission fluid; have
your wheels aligned and tires rotated; and replace the air filter if needed.
Make sure all used vehicle fluids are recycled or disposed of safely.
•Change the oil. In addition to making your car or truck last longer, replacing
the oil and oil filter regularly will also help fuel economy. Check your owner's
manual for specific recommendations about how often to change. Ask the service
station if they recycle used oil, or if you do it yourself, take your old oil
to someplace that does recycle. Ask for recycled oil as a replacement.
•Have your vehicle's emission control system checked periodically. Take it
in for service if an instrument panel warning light comes on.
Careful Fill-Ups
•Use regular gasoline unless your owner's manual says otherwise. Unless
your car requires premium, high-octane fuels improve neither fuel economy nor
performance and will just waste your money.
•Don't overfill the gas tank or try to top it off beyond where the automatic
nozzle clicks off. Spilled gasoline evaporates to aggravate smog formation
and can leak into groundwater.
•Patronize gas stations that have vapor-recovery nozzles (those black, accordion-looking
plastic devices attached to the nozzle) whenever you can.
Prudent Parking
•Park in the shade in summer to keep your car cool and minimize evaporation
of fuel.
•If you have a garage, use it as much as possible to keep your car warm in
winter and cool in summer.
•If you have to park outdoors, windshield shades can cut down on summer heat
and help keep the frost off in the winter.
