Need more info about 1991 Buick Century oil changes? Turn to Firestone Complete Auto Care! We're experts in more than tires. We know the ins and outs of motor oil, too. We couldn’t put it better than our technician, Brianna. She likes to explain to customers that, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”
Your 1991 Century’s oil should be changed according to Buick’s recommended oil change intervals. Check out mileage and month info for your Century in the above table. Outside of Buick-recommended oil change intervals, your Century may need an oil change if your check engine 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 may also need an oil change more frequently than Buick recommends if you haul heavy loads, frequent dusty roads, enjoy off-roading, or go long distances at low speeds. More frequent oil changes generally won't harm your Buick Century. 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 Century. Buick has specifically identified either synthetic or conventional as the ideal engine oil for your 1991 Century. Motor oil helps lubricate the engine’s moving parts, keep the engine cool, and keep harmful substances from building up inside the engine. In an oil change service, a technician will change your Century's oil, replace and recycle the old oil and filter, check all of your other filters, refill vital car fluids, and perform a courtesy inspection on your entire vehicle. You can drive with confidence knowing that we look out for you and your Century by taking into account your driving style, and odometer.
Wondering if we carry the right motor oil for your Buick? We stock outstanding motor oils because that's what your engine deserves. Consult Buick's recommendations to select the right 1991 Century oil and talk with a teammate to learn more about our oil options: Quaker State® Advanced Durability™ conventional oil, Pennzoil® High Mileage Vehicle® motor oil, Pennzoil Platinum® Full Synthetic motor oil with PurePlus™ Technology, and Shell Rotella® heavy-duty engine oil. There are plenty of motor oils on the market today, so why do we prefer these brands? They are tested and trusted. For instance, when tested in taxi fleets across North America, Quaker State was shown to provide 2x more protection than the industry standard.  And Pennzoil? Unlike traditional synthetic motor oils, the Pennzoil Platinum® Full Synthetic line of motor oils with PurePlus® Technology is formulated from pure natural gas, which helps lead to better performance. But don't forget about Shell Rotella for heavy-duty engines. It's made for gasoline and diesel engines that need to withstand rugged conditions, and is uniquely strengthened to deliver heightened performance in extreme temperatures, increased wear protection, and better oxidation resistance. Always refer to Buick's recommendations before going with a new or different motor oil for your 1991 Buick Century.
