Not sure how or where to get your GMC C1500’s oil changed? Look no further than Firestone Complete Auto Care! We are experts in car care — not just tires. We know the ins and outs of motor oil, too. 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.
GMC recommends having your 1985 GMC C1500’s motor oil changed at regular intervals. See mileage and month specifics in the above table. No matter the mileage, your C1500 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 notice excess vehicle exhaust. You may also need an oil change more frequently than GMC recommends if you haul heavy loads, drive in dusty areas, enjoy off-roading, or drive at low speeds for long distances. In general, being extra-diligent about oil changes won’t damage your GMC C1500. 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 C1500. GMC has specifically identified either synthetic or conventional as the ideal engine oil for your 1985 C1500. Motor oil reduces friction between engine components, maintain proper engine temperature, and prevent harmful substances from accumulating in the engine. During an oil change, one of our techs will change your C1500’s oil, replace and recycle your used oil and oil filter, inspect all of your other filters, top-off important fluids, and perform a free inspection on the rest of your vehicle. You can rest assured knowing that we seek to do what’s best for your C1500 by considering your driving preferences, local climate,
