If you have a car or truck with a diesel engine you already know that you must treat your engine in a different manner than a gasoline engine.

Since diesel engines have no electrical ignition parts, they depend on higher compression to ignite the fuel, with almost three times the pressure of a gas engine. To keep your diesel running in top condition, the following tips should be followed:

Caring for your diesel engine

If you have a car or truck with a diesel engine you already know that you must treat your engine in a different manner than a gasoline engine.

Since diesel engines have no electrical ignition parts, they depend on higher compression to ignite the fuel, with almost three times the pressure of a gas engine. To keep your diesel running in top condition, the following tips should be followed:

  • Oil Changes: Given the high compression and heat of a diesel engine, regularly changing your oil and oil filter is critical. Corrosive particles, dirt and other materials can easily enter your oil system.
  • Air Filter: Diesel engines need to breathe. Be sure to check your air filtration system on a regular basis.
  • Cooling System: With more heat generated, the cooling system is under heavier stress. Studies have indicated that overheating is to blame for approximately 50% of engine failures.
  • Engine vibration: Diesel engines work hard. Be sure to have your engine mounts and coolant hoses checked regularly to be sure they are secure. It’s not unusual to need your engine mounting bolts re-torqued at intervals.
  • Gaskets: Gaskets should be checked regularly to be sure they are not leaking. Normally, if one gasket is found to leak the others may be close to failure as well.
