The Importance of Engine Oil

Engine oil maintenance is an often overlooked and underestimated preventative maintenance care service for trucks. Not only does engine oil lubricates the moving parts of a diesel engine, but also helps to reduce wear from friction, regulate engine temperature, and prevent corrosion. In all classes of diesel trucks, engine oil has to withstand extreme conditions, high temperatures, and often heavy loads. That’s a lot of responsibility, which is why regular oil changes, and using the proper oil are key to maintaining the health of your engine.

Our certified team of technicians specializes in mobile express oil and lube service to keep your diesel truck lubricated and road-ready. When you stay on top of your truck’s lube and oil changes, your vehicle will last longer, drive smoother, have better fuel economy and save you money down the road in extensive repairs.

  • Differential oil: This oil lubricates and cools the differential, which is responsible for transmitting power from the transmission to the wheels.
  • Transmission fluid: This fluid performs several tasks, including lubrication, cooling, cleaning, and protection of the transmission components from wear and tear. It also helps transmit power from the engine to the wheels.
  • Coolant: The coolant helps regulate engine temperature and prevent overheating. It should be checked and changed periodically to maintain its efficiency.
  • Power steering fluid: This fluid facilitates smoother and easier steering and should be checked regularly.
  • Brake fluid: Brake fluid transfers force from the brake pedal to the brake pads, bringing the vehicle to a stop. It is important to use the correct type of brake fluid for your vehicle.
