Increasing the fuel mileage in your diesel vehicle may seem a bit challenging at first, but when you break it down into small, easy steps, the job becomes much simpler. There are quite a few things you can do to get better fuel mileage, and some cost very little money. Check with the car's manufacturer before you install any parts in your car's engine that may void the service warranty.
Purchase and have a mechanic install special diesel performance chips in your engine's computer. These chips help to increase the power and efficiency of your car's engine, which helps the fuel mileage. However, these chips cannot be put into older cars without computers for obvious reasons. Diesel performance chips can be purchased at http://www.parleysdieselperformance.com/site/988369/page/694621 and many retail stores that sell performance automotive parts.
Use fuel additives specifically made for diesel engines. These can make a significant improvement in your car's mileage for very little money. Different fuel additives can be purchased online at http://www.fueladditiveonline.com/ and most retail stores that sell automotive accessories.
Update your exhaust system. A performance exhaust system will reduce the energy needed to expel exhaust from you car, improving your gas mileage. Performance exhaust parts can be found at http://www.dieselperformanceexhaust.com/.
Replace the air filter in your car frequently. Most mechanics and manufacturers recommend replacing the air filter every 15,000 miles for city drivers and more frequently in the country or for drivers who frequently travel over dirt roads. Purchase high-performance air filters if you drive a lot. Buying a better air filter with a longer life can help you get better mileage over a longer period of time. While this is true for all vehicles, it is particularly important in diesel vehicles, as they use unrefined fuel.

Purchase a premium fuel injection pump. If your fuel injection pump is not working well, your fuel will not burn as evenly and efficiently as it should.
Install specially designed plates on the back of a trailer to prevent drag. These plates can help to save between three and five percent on fuel costs. These can be found through Airman Inc. at http://www.dieselboss.com/wedge.htm.
