Not sure how or where to get your GMC K3500’s oil changed? Get the advice you need at Firestone Complete Auto Care! We are experts in car care — not just tires. Oil and lube services are also our specialties. After all, "Oil is the blood of the engine. It's the #1 thing you can do for your car," says our maintenance technician, Brianna.
Your 1986 K3500’s oil should be changed according to GMC’s recommended oil change intervals. See mileage and month specifics in the above table. No matter the mileage, your K3500 may need its oil changed ASAP if your check engine light is on, you hear engine knocking, sense an oil smell in the cabin, or see an excess amount of vehicle exhaust. You may also need an oil change more frequently than GMC recommends if you haul heavy loads, drive in dusty terrain, adventure off-road, or go long distances at low speeds. More frequent oil changes generally won't harm your GMC K3500. 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 K3500 motor oil: either synthetic or conventional. GMC has recommendations as to whether conventional or synthetic oil is the best oil for 1986 GMC K3500 vehicles. This oil helps lubricate engine parts, regulate engine temperature, and prevent the build-up of harmful substances within the engine. In an oil change service, one of our techs will change your K3500’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 courtesy inspection on your entire vehicle. You can rest assured knowing that we seek to do what’s best for your K3500 by considering your driving preferences, weather and road conditions,
