Looking for oil change recommendations for your 1986 GMC K2500? Get the advice you need at Firestone Complete Auto Care! Our expertise goes beyond tires. We know all about motor oil, too. We couldn’t put it better than our technician, Brianna. She likes to explain to customers that, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”
GMC recommends having your 1986 GMC K2500’s motor oil changed at regular intervals. Check out mileage and month info for your K2500 in the above table. 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 excess vehicle exhaust. You might need an oil change more frequently than what’s recommended by GMC if you regularly haul heavy loads, drive in dusty terrain, adventure off-road, or drive at low speeds for long distances. In general, being extra-diligent about oil changes won’t damage 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.
Your local Firestone Complete Auto Care has the right 1986 GMC K2500 motor oil: either synthetic or conventional. GMC has recommendations as to whether conventional or synthetic oil is the best oil for 1986 GMC K2500 vehicles. Motor oil reduces friction between engine components, regulate engine temperature, and prevent harmful substances from accumulating in the engine. During your oil change service, one of our techs will change your K2500’s oil, replace and recycle your used oil and filter, inspect the rest of your car’s filters, refill vital car fluids, and perform a free inspection on the rest of your vehicle. You can drive with confidence knowing that we look out for you and your K2500 by taking into account your driving habits, and odometer.
