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.”
Your 1985 C1500 Suburban’s oil should be changed according to GMC’s recommended oil change intervals. Check out mileage and month info for your C1500 Suburban in the above table. No matter the mileage, your C1500 Suburban may need its oil changed ASAP if your check engine light is on, you hear knocking sounds coming from the engine, smell oil inside the car, or notice an unusual amount of exhaust. You may also need an oil change more frequently than GMC recommends if you haul heavy loads, frequent dusty roads, adventure off-road, or go at low speeds on long distance trips. More frequent oil changes generally won't harm your GMC C1500 Suburban. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.
Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your GMC C1500 Suburban. GMC has recommendations as to whether conventional or synthetic oil is the ideal engine oil for your 1985 C1500 Suburban. This oil helps lubricate engine parts, maintain proper engine temperature, and prevent harmful substances from accumulating in the engine. In an oil change service, a technician will change your C1500 Suburban's oil, replace and recycle the old oil and filter, check all of your other filters, top-off important 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 C1500 Suburban by considering your driving style, and odometer.
