Not sure how or where to get your Buick Roadmaster’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.
Buick recommends having your 1991 Buick Roadmaster’s motor oil changed at regular intervals. Check out mileage and month info for your Roadmaster in the above table. No matter the mileage, your Roadmaster 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 might need an oil change more frequently than what’s recommended by Buick if you regularly haul heavy loads, frequent dusty roads, go off-roading a lot, or go long distances at low speeds. In general, being extra-diligent about oil changes won’t damage your Buick Roadmaster. 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 Buick Roadmaster. Buick has most likely outlined either synthetic or conventional as the best motor oil for your 1991 Roadmaster. 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 Roadmaster's oil, replace and recycle your used oil and filter, inspect all of your other filters, top-off essential 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 Roadmaster by considering your driving style, and mileage.
