Need more info about 1985 GMC K2500 oil changes? Look no further than Firestone Complete Auto Care! We're experts in more than tires. We know all about motor oil, too. After all, like our maintenance technician Brianna says, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”
GMC recommends changing your 1985 K2500’s oil at regular intervals. Check the interval for your vehicle mileage in the table above. Outside of GMC-recommended oil change intervals, your K2500 may need an oil change if your check engine light is on, you hear knocking sounds coming from the engine, sense an oil smell in the cabin, or notice an unusual amount of exhaust. You may also need an oil change more frequently than GMC recommends if you haul heavy loads, drive in dusty areas, go off-roading a lot, or go long distances at low speeds. Generally, getting more frequent oil changes won’t hurt your GMC K2500. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.
Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your GMC K2500. GMC has specifically identified either synthetic or conventional as the best oil for 1985 GMC K2500 vehicles. Motor oil reduces friction between engine components, regulate engine temperature, and prevent harmful substances from accumulating in the engine. During an oil change, one of our techs will change your K2500’s oil, replace and recycle your used oil and filter, check all of your other filters, refill vital car fluids, and perform a free inspection on the rest of your vehicle. You can drive easy knowing that we strive to do what's best for your vehicle and take into account your driving style, and the number of miles on your odometer.
