Pump Gas Early in the morning or in cold temperature and Pump slowly
Only buy or fill up your car or truck in the early
morning when the ground temperature is still cold.
Remember that all service stations have their storage
tanks buried below ground. The colder the ground the
more dense the gasoline, when it gets warmer gasoline
expands, so buying in the afternoon or in the
evening....your gallon is not exactly a gallon. In the
petroleum business, the specific gravity and the
temperature of the gasoline, diesel and jet fuel,
ethanol and other petroleum products plays an important
role.
A 1-degree rise in temperature is a big deal for this
business. But the service stations do not have
temperature compensation at the pumps.

Keep Your Engine Properly Tuned
Fixing
a car that is noticeably out of tune or has failed
an emissions test can improve its gas mileage by an
average of 4 percent, though results vary based on
the kind of repair and how well it is done.
Fixing a serious maintenance problem, such as a faulty oxygen sensor, can improve your mileage by as much as 40 percent.

Keep Tires Properly Inflated
You
can improve your gas mileage by up to 3.3 percent by
keeping your tires inflated to the proper pressure.
Under-inflated tires can lower gas mileage by 0.3
percent for every 1 psi drop in pressure of all four
tires. Properly inflated tires are safer and last
longer. I usually add 5 psi more then recommended to
get better mileage.
The proper tire pressure for your vehicle is usually found on a sticker in the driver's side door jamb or the glove box and in your owner's manual. Do not use the maximum pressure printed on the tire's sidewall.

Use the Recommended Grade of Motor Oil
You can improve your gas mileage by 1–2 percent by using the manufacturer's recommended grade of motor oil. For example, using 10W-30 motor oil in an engine designed to use 5W-30 can lower your gas mileage by 1–2 percent. Using 5W-30 in an engine designed for 5W-20 can lower your gas mileage by 1–1.5 percent. Also, look for motor oil that says "Energy Conserving" on the API performance symbol to be sure it contains friction-reducing additives. If you have a new car 0-20 is a great oil for you.

NEW INFORMATION: Replacing a Clogged Air Filter on Modern Cars Improves Performance but Not MPG
A new study
shows that replacing a clogged air filter on cars
with fuel-injected, computer-controlled gasoline
engines does not improve fuel economy but it can
improve acceleration time by around 6 to 11 percent.
This kind of engine is prevalent on most gasoline
cars manufactured from the early 1980s onward.
Tests suggest that replacing a clogged air filter on an older car with a carbureted engine may improve fuel economy 2 to 6 percent under normal replacement conditions or up to 14 percent if the filter is so clogged that it significantly affects drivability.
The effect of a clogged air filter on diesel vehicles will be tested in the near future.
Note: Cost savings are based on an assumed fuel price of $3.87/gallon.
