Smart Ways to Save Gasoline
Observe the speed limit. You decrease mileage about 4 percent for every five miles an hour faster you drive on the highway.
Accelerate smoothly. Drive at a steady pace.
Decelerate early for stops. Braking hard wastes gas and wears tires and brakes out faster.
If your car has a manual transmission, shift to the top gear as soon as practical.
Don't let your engine idle for more than a minute. It's more efficient (and less polluting) to turn it off and start up again.
Use gasoline octane and oil viscosity recommended by the car manufacturer.
Check tire pressure regularly. You use about 2 percent more fuel for every pound per square inch of underinflation.
Follow you car's maintenance schedule faithfully, especially with respect to oil changes.
