Running on diesel doesn't mean you can't save on your fuel costs. It may seem like most fuel-saving tips are aimed at those driving gasoline-powered cars, but there are some ways you can burn less diesel. The following tips can help you get the most of your next fill-up.

Tip #1: Don't Be Idle

Idleness is no good whether you are a person or a vehicle. Not only does sitting idle burn fuel, it can also cause wet stacking. This is when diesel gets into the oil via the crankcase. Idle the vehicle to warm it up for no more than 5 to 7 minutes when temperatures are below freezing, or up to 3 minutes when temperatures are above freezing. Cut the engine if you will be waiting to drive for more than a few minutes, instead of letting it idle as you wait.

Tip #2: Skip the AC – Sometimes

Running the air conditioner uses fuel, which means that cold air climate control is eating into your gas mileage. When driving in the city, drop a window instead when you want to cool off. The only exception is when you are driving for an extended distance on the highway. The drag of having a window down may actually lead to more fuel consumption, so it's better to run the AC sparingly.

Tip #3: Watch Your Speed

Speed is a major reason for excess fuel use, whether you are driving a diesel or gasoline powered vehicle. Most vehicles are tuned to deliver the best fuel economy somewhere near average highway speeds of 65 miles per hour. You can quickly find out what the "sweet spot" for fuel consumption is for your vehicle by searching the make, model and year online. As a general rule, though, don't speed and choose routes with the least stop-and-go driving if you want to conserve fuel.

Tip #4: Keep It Maintained

Finally, make sure the other parts of your diesel vehicle are in top condition. Get regular oil and filter changes at the manufacturer recommended intervals. You also need to replace the air filter at the recommended intervals, but it's a good idea to check it every few months to make sure it is still clean and whole. Make sure your tires are properly aired up to the PSI specified on the sidewall of the tire. Sometimes, fuel injectors can become covered in residue from impurities in the diesel, so having these inspected and cleaned during your annual tuneup may also help fuel mileage.
