Looking for oil change recommendations for your 1991 Buick Park Avenue? Look no further than Firestone Complete Auto Care! We are experts in car care — not just tires. Oil and lube services are also our specialties. After all, like our maintenance technician Brianna says, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”
Buick recommends having your 1991 Buick Park Avenue’s motor oil changed at regular intervals. Check the interval for your vehicle mileage in the table above. Outside of Buick-recommended oil change intervals, your Park Avenue may need an oil change if your check engine 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 may also need an oil change more frequently than Buick recommends if you haul heavy loads, frequent dusty roads, adventure off-road, or drive at low speeds for long distances. In general, being extra-diligent about oil changes won’t damage your Buick Park Avenue. 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 1991 Buick Park Avenue motor oil: either synthetic or conventional. Buick has most likely outlined either synthetic or conventional as the best oil for 1991 Buick Park Avenue vehicles. Motor oil reduces friction between engine components, regulate engine temperature, and keep harmful substances from building up inside the engine. During an oil change, an auto technician will change your Park Avenue’s oil, replace and recycle your used oil and oil filter, check all of your other filters, refill vital car fluids, and visually inspect the rest of the vehicle. You can drive with confidence knowing that we look out for you and your Park Avenue by taking into account your driving habits, weather and road conditions,
