Not sure how or where to get your Chevrolet C20 Suburban’s oil changed? Get the advice you need at 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.
Your 1985 C20 Suburban’s oil should be changed according to Chevrolet’s recommended oil change intervals. See mileage and month specifics in the above table. Outside of Chevrolet-recommended oil change intervals, your C20 Suburban may need an oil change if your check engine light is on, you hear engine knocking, smell oil inside the vehicle, or notice an unusual amount of exhaust. You might need an oil change more frequently than what’s recommended by Chevrolet if you regularly haul heavy loads, frequent dusty roads, go off-roading a lot, or drive at low speeds for long distances. Generally, getting more frequent oil changes won’t hurt your Chevrolet C20 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.
Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your Chevrolet C20 Suburban. Chevrolet has specifically identified either synthetic or conventional as the best motor oil for your 1985 C20 Suburban. This oil helps lubricate engine parts, regulate engine temperature, and keep harmful substances from building up inside the engine. During your oil change service, one of our techs will change your C20 Suburban’s oil, replace and recycle your used oil and oil filter, check all of your other filters, top-off essential fluids, and perform a free inspection on the rest of your vehicle. You can drive easy knowing that we strive to do what's best for your vehicle and take into account your driving style, weather and road conditions,
