What Maintenance Does a Diesel Truck Need?

Diesel trucks aren’t the same as your typical gas truck. Diesel engines are made to last longer and run a little differently than gas engines. That’s why it’s important to take care of your diesel truck and make sure it’s getting the proper maintenance.

What sets diesel engine service apart from gas truck maintenance?

Oil

For starters, diesel trucks need to have their oil changed more frequently. Depending on how often you use your truck, you may need to change the oil every 3,000 to 5,000 miles. You should also use a higher-quality oil designed for diesel engines.

Fuel Filters

Diesel trucks also need to have their fuel filters changed more frequently than gas trucks.Fuel filters help remove contaminants from the fuel, and over time they can become clogged. This can lead to poor engine performance, so it’s important to change the fuel filter according to the manufacturer’s recommendations.

Exhaust Systems

Finally, diesel trucks need to have their exhaust systems cleaned more often than gas trucks. This is because diesel engines tend to produce more soot and other contaminants than gasoline engines. If these contaminants build up in the exhaust system, they can cause damage to the engine. So it’s important to have the exhaust system cleaned every few months to prevent problems.

By following these tips, you can keep your diesel vehicle in good shape and avoid costly repairs. Be sure to talk to a diesel mechanic if you have any questions about maintaining your truck.

Other Diesel Truck Maintenance

Diesel trucks may be built differently than regular gas trucks, but they still by and large need all of the same maintenance as any other vehicle.

Besides more frequent oil and fuel filter changes, along with more frequent exhaust system cleanings, your diesel truck needs all of the same maintenance as a regular vehicle, like:

  • Tires — rotated and inflated to the correct PSI; check for tread wear and uneven wear.
  • Brakes — check for wear and tear, and replace as needed.
  • Windshield wipers — make sure they’re in good condition and replaced as needed.
  • Lights — check all bulbs and replace as needed.
  • Fluids — check all fluids (oil, coolant, power steering, etc.) and top off or replace as needed.
  • Transmission — if you notice any issues with shifting, have your truck’s transmission checked out by a professional.

Overall, just be sure to keep up with the regular maintenance for your diesel truck and it will serve you well for years to come.
