How to Increase Diesel Fuel Mileage

In the past, diesel fuel was the least expensive gas choice for many vehicles. Nowadays, however, diesel fuel prices have been steadily on the rise. You are looking for ways to improve the number of miles you can get from your diesel fill-ups. You can make several enhancements to your vehicle to increase diesel fuel mileage when driving. This can save you money, especially if you drive a diesel truck that is expensive to fill.

Instructions

1. Update your exhaust system. With a newer or performance exhaust system, your engine will not have to work so hard to blow exhaust from the vehicle. This, in turn, will help improve your diesel fuel mileage.

2. Consider installing a performance filter for your diesel vehicle. A performance filter can help your vehicle respond quicker to the throttle, which can help improve the vehicle's mileage.

3. Try a diesel fuel additive. Diesel fuel additives have multiple purposes, including the ability to clean your engine as well as eliminate moisture that affects lubrication of the fuel as it passes through. Fuel additives have shown to improve diesel gas mileage as high as 10 percent.

4. Adjust your driving speed. Another way to increase diesel fuel mileage is to drive at a steady speed, typically between 50 to 60 miles per hour. This allows your engine not to work as hard to maintain your driving speed.

5. Turn off the air conditioning in your diesel vehicle. Air conditioning units are known culprits for using up automobile fuel. If possible, keep it turned off as often as possible to improve diesel fuel mileage.

6. Reduce the vehicle's excess weight. The more weight you tow, the more diesel fuel you will burn. Carrying excessive weight in the cab as well can affect fuel mileage as well.
