Truck Oil & Fluid Services in Cumming, Georgia

If you want to keep your truck running for as long as possible, you need to ensure your oil and fluids are changed on a regular basis. Over time, your fluids break down and become less effective at lubricating moving parts and absorbing radiant heat. When this breakdown occurs, heat and friction increase and the lifespan of each component with old fluid decreases. The lifespan of each fluid depends on how hot the component it’s within gets. For example, your engine oil needs to be changed at a far quicker rate than that of transmission fluid, for a transmission does not have a combustion chamber.

Components That Require Oil or Fluid

Diesel Engines

Your heavy-duty diesel engines require both engine oil and coolant to function properly. The engine oil lubricates the engine’s inner components, and the coolant absorbs radiant heat. These two fluids allow for your engine’s operating temperature to be controlled. If either of these fluids breaks down, your engine will overheat and may become damaged. Common damage of prolonged overheating includes blown head gaskets and warped pistons. Engine oil should be replaced every 3 to 6 thousand miles, whereas engine coolant needs to be replaced every 30 to 60 thousand miles. 

Transmission and Differentials

Your transmission and differentials are important drivetrain components. They both contain a series of gears that need to be lubricated at all times. Without this lubrication, the gears may erode due to excess friction and heat. Most manufacturers recommend that the fluid in both these components be changed every 30 to 60 thousand miles. 

Steering Fluid

Your steering assembly uses fluid to move your wheels back and forth. This isn’t necessarily true for semi-trucks with electric steering, but most trucks use hydraulic-based assemblies. This steering fluid also needs to be replaced. Symptoms of bad steering fluid include loud noises when steering, overheating steering fluid and loss of power steering.
