Tips for Saving Fuel in Your Diesel Truck

The price of diesel fuel varies across the country and is always changing. But there is one thing that never changes: all diesel truck drivers are looking for tips for saving fuel. Here are some ways you can lower fuel costs for your diesel truck:

Easy on the Accelerator

Among the most impactful fuel-saving tips is to ease up on the lead foot. Saving fuel is all about efficiency and if you tend to travel at a higher speed you are using more fuel in your truck. Being intentional about not speeding with heavy acceleration will help you save money at the pump.

Better Tires = Better Mileage

Having a heavy truck capable of towing and carrying heavy objects is the reason you probably bought it, but more weight can put a drag on your fuel efficiency. There is something you can do to ease resistance, and it has to do with the tire tread.

Tire treads impact your fuel economy because up to 50% of the resistance on the road comes from the tread. Simply put, the more shallow your tread is, the better mileage you’re going to get. That means if you’ve switched out your tires for an aggressive-looking tread that can chew through the toughest terrain, you’ve probably reduced your chance of getting better gas mileage on the road.

Proper Maintenance

There are many reasons why you should be marking your calendar to take your diesel truck in for maintenance, but one of them is related to gas mileage. You can get up to a 4.5% increase in fuel efficiency by using the proper motor oil.

Petroleum-based motor oils break down over time, which means they don’t lubricate like they should. A better product is synthetic oil, which has no change in viscosity over time, which means it will lubricate the internal parts of the engine better than petroleum-based oil, providing less resistance and improved fuel efficiency.

Quick Tips

Looking for some more quick tips on what you can do to save on fuel? Check these out:

  • Don’t idle: Shut down your engine when you’re at a standstill and don’t plan on moving anytime soon. Idling can waste roughly .75 gallons of fuel per hour.
  • Maintain the correct tire pressure.
  • Turn off unused accessories. 
  • Keep your speed low.
  • Use cruise control.
  • Ensure your route is the shortest and most efficient possible.
