How Can You Increase Fuel Economy on a Diesel Pickup?

by | Aug 3, 2023

With today’s high diesel prices, learning how to increase fuel economy on your diesel pickup can offer you significant savings. And, while the measures required to do so aren’t necessarily free, the end result will be worth it. That’s because you’ll enjoy improved engine performance and lower overall fuel costs.

Let’s take a closer look at some simple ways you can increase fuel mileage on your diesel truck so you can start saving money right away.

5 Ways to Increase Fuel Economy on a Diesel Pickup

1. Follow a regular preventative maintenance schedule.

At the risk of sounding like a broken record, we’ll repeat one of the most important aspects of automotive care. Preventative maintenance is essential for EVERY vehicle!

To increase fuel economy on a diesel pickup, there are certain maintenance items that are especially important. These include:

  • Routine oil changes
  • Regular air and fuel filter changes
  • Periodic engine tune-ups
  • Routine replacement of transmission oil, transfer case oil, and differential oil

By following these diesel maintenance tips, you can keep your truck’s engine running smoothly and efficiently. The end result will be improved fuel economy and increased power.

2. Practice proper tire maintenance.

While this IS one way to increase fuel economy on a diesel pickup, it’s also true for every vehicle. When you drive on underinflated or misaligned tires, there’s more rolling resistance. This decreases fuel economy and leaves you paying more at the pump.

Make a habit of regularly checking your truck’s tire pressures, especially before hauling heavy loads. It’s also a good idea to check the pressure when there are significant weather changes as outdoor temperature variations can affect tire pressure. While you’re at it, visually inspect your tires for cracks, bulges, or other signs of abnormal wear. While these may not directly affect your fuel mileage, they could affect your driving safety.

3. Use low rolling resistance tires.

While we’re on the subject of tires, it’s important to note that the type of tires you have on your truck matters. According to research done by the U.S. Department of Energy, using low rolling resistance tires can translate to as much as a 10% savings in fuel economy. Since these tires are often more expensive, you’ll need to evaluate whether or not the extra cost is worth the potential fuel savings.

4. Increase fuel economy with aerodynamic accessories on your diesel pickup.

There are a wide variety of truck accessories on the market today. While some have more to do with appearance than function, others can have a positive impact on your fuel mileage. Aerodynamic accessories like tonneau covers, for example, can improve fuel economy by reducing drag. They’re also handy for protecting items stored in the truck bed during travel or while parked.

5. Adopt fuel-efficient driving habits.

This is one way to increase fuel economy on your diesel pickup without having to spend a dime. Avoid rapid acceleration and sudden stops, use cruise control on highways, and reduce idling time. These are all healthy driving habits that can improve fuel mileage and save you money.
