How to Increase the MPG in a Chevy K2500

by Mark Nero

The Chevy K2500 is a truck that was first introduced by Chevrolet in 1988 and was produced for 12 years, until being replaced by a heavy-duty version of the Chevy Silverado in 2000. Without modifications to the vehicle, the K3500's fuel economy can range from 11 miles per gallon to about 22, depending on a handful of factors, including the model year and whether or not it has a stick shift or automatic transmission. There are numerous ways to increase a K2500's gas mileage without resorting to mechanical work.

Step 1

Drive more sensibly. Avoid aggressive maneuvers in traffic like speeding, quick braking and rapid acceleration, all of which suck up gas and hurt the truck's gas mileage. Also, watch your speed, since the gas mileage in Chevy trucks usually decreases rapidly at speeds over 60 MPH.

Step 2

Remove excess weight from the vehicle. Since the older model Chevy K2500s are heavy duty pickup trucks, some owners use them to haul large, heavy objects. But when the truck's not hauling anything, all heavy items should be removed. The lighter the vehicle is, the less the drive resistance and the better the gas mileage.

Step 3

Monitor and adjust the truck's tire pressure as needed. Under-inflated tires can increase the amount of work the engine has to put in, which results in more fuel being burned. The maximum recommended pressure for each tire should be printed on the tires' sidewalls.

Step 4

Change your car's oil regularly. Pollutants in dirty oil can affect the truck's engine, causing it to work harder and burn more fuel in the process.

Replace dirty air filters as needed. A dirty air filter can reduce the air flow in a Chevy K2500, thereby wasting energy and affecting fuel performance.
