Truck Oil & Fluid Services in Vinita, OK

Did you know that the oil and fluids in your heavy-duty vehicle break down over time? Every fluid in your vehicle needs to be changed at some point, it’s just a matter of identifying the service intervals for each fluid. Generally, a good rule of thumb is that the hotter the component’s fluid gets, the sooner it needs to be changed. For example, your heavy-duty engine creates a lot of heat, whereas your differential does not. As such, your engine oil needs to be changed far more frequently than your differential fluid. Here at GKT Truck Repair, we have services for every oil and fluid type. Whether you want to flush the coolant out of your engine or change your transmission fluid, you can count on us to provide the high-quality services you and your truck deserve.

Components That Require Oil or Fluid

Diesel Engine

Your diesel engine has many moving components that must be lubricated at all times. This lubrication allows your components to move against one another without intense friction. If this lubrication fails to eradicate friction, your engine will get hotter than your coolant system can handle. Not to mention you’ll likely start to see metal shavings in your oil, which essentially means your engine’s components are grinding against each other. 

Your engine coolant is another major fluid in your heavy-duty vehicle. Coolant is pushed through your engine block, where it then absorbs your engine’s heat. It then exits your block and enters your radiator, where the heat is dispersed. Like engine oil, your coolant will break down over time and lose its ability to absorb heat. Hence the need for routine coolant changes. 


Your transmission is a series of gears that optimize your engine’s power. These gears need to be lubricated at all times in order to avoid complete transmission failure. Fortunately, your transmission fluid tends to last a lot longer than your engine oil because no internal combustion is happening within the transmission.


Your differential is very similar to your transmission in that it doesn’t need fluid changes very often and is essentially a group of moving gears. Rather than optimizing your engine’s power, your differentials are responsible for moving power from your driveshaft to your drive axles. Be sure to get this fluid change around the same time you change your transmission fluid.
