Not sure how or where to get your GMC R1500 Suburban’s oil changed? Get the advice you need at Firestone Complete Auto Care! Our expertise goes beyond tires. We know all about 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 1989 GMC R1500 Suburban’s motor oil changed at regular intervals. Check the interval for your vehicle mileage in the table above. Your R1500 Suburban may need an oil change right away if your check engine/oil change light is on, you hear knock knock knock 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 areas, adventure off-road, or go long distances at low speeds. In general, being extra-diligent about oil changes won’t damage your GMC R1500 Suburban. In fact, more frequent oil changes give our technicians more opportunities to catch and alert you to any issues, like worn brake pads or a weak battery.

During an oil change, a technician will change your R1500 Suburban's oil, replace and recycle your used oil and filter, check all of your other filters, top-off important fluids, and perform a courtesy inspection on your entire 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.
