How to Improve Gas Mileage in a Cavalier

by John Smith

The most obvious way to improve gas mileage in a Chevy Cavalier--or any vehicle for that matter--is to improve your driving habits. These include staying within the posted speed limits and combining errands. The next way is to service your Cavalier on a regular basis. Finally, you can add aftermarket parts to your vehicle specifically designed to improve car performance and gas mileage.

1

Install an upgraded and performance-enhanced exhaust system to replace stock equipment. These new systems improve the exhaust flow with pipes that are wider and straighter. Improved exhaust improves gas mileage in a car.

2

Install an upgraded air filter. These air filters improve gas mileage and are designed to last for the lifetime of the car. They are available at auto parts stores and online. They generally are twice as expensive as a standard air filter, usually in the $40 range, but well worth it when you consider most air filters need to be replaced once a year. The frequency with which you replace a standard air filter depends on how many miles you drive and the condition of your car.

3

Install a new and improved air intake kit to replace your old air box and filter. These kits allow air to flow into the engine faster than stock air boxes, which also improves your gas mileage.

4

Buy new tires that have radial designs for improved gas mileage by reducing rolling resistance. Rolling resistance is also reduced by placing larger diameter tires on the rear wheels. Check the tire manufacturer's specifications for maximum tire pressure. Check to make sure your tires have the correct pressure at all times.

5

Tune up your Chevy Cavalier as needed. Tell your mechanic to look for fouled fuel injectors and to check the spark plugs. A Chevy Cavalier should be tuned up every 60,000 to 100,000 miles, depending on the age of the car. Older cars need to be tuned up more often.

6

Take your Chevy Cavalier to a mechanic for a brake inspection. Brakes that bind or stick lower gas mileage.

7

Ensure that the oil is clean and have it changed according to the mileage instructions in the Cavalier's owner's manual. Cavaliers should have an oil change every 3,000 miles.

8

Use the level of fuel octane recommended in the owner's manual. Chevrolet Cavaliers operate well on regular unleaded fuel (87 octane) when they are tuned up and running properly.

Warning

  • Be wary of gas-saving devices, including gas and oil additives, which have received mixed reviews at best.
