Not sure how or where to get your Oldsmobile Cutlass Supreme’s oil changed? Turn to Firestone Complete Auto Care! We are experts in car care — not just 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.
Oldsmobile recommends changing your 1985 Cutlass Supreme’s oil at regular intervals. Check the interval for your vehicle mileage in the table above. Your Cutlass Supreme may need an oil change right away if your check engine/oil change light is on, you hear knocking sounds coming from the engine, sense an oil smell in the cabin, or notice an unusual amount of exhaust. You might need an oil change more frequently than what’s recommended by Oldsmobile if you regularly 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 Oldsmobile Cutlass Supreme. 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 1985 Oldsmobile Cutlass Supreme motor oil: either synthetic or conventional. Oldsmobile has specifically identified either synthetic or conventional as the best motor oil for your 1985 Cutlass Supreme. Motor oil reduces friction between engine components, maintain proper engine temperature, and prevent the build-up of harmful substances within the engine. During your oil change service, a technician will change your Cutlass Supreme's oil, replace and recycle your used oil and oil filter, inspect the rest of your car’s 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 Cutlass Supreme by considering your driving habits, and the number of miles on your odometer.
Wondering if we carry the right motor oil for your Oldsmobile? We stock outstanding motor oils because that's what your engine deserves.
