Looking for oil change recommendations for your 1999 Buick Century? Get the advice you need at 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 1999 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. Your Century may need an oil change right away if your check engine/oil change light is on, you hear engine knocking, 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, go off-roading a lot, 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.
Your local Firestone Complete Auto Care has the right 1999 Buick Century motor oil: either synthetic or conventional. Buick has specifically identified either synthetic or conventional as the ideal engine oil for your 1999 Century. Motor oil helps lubricate the engine’s moving parts, keep the engine cool, and prevent the build-up of harmful substances within the engine. During an oil change, one of our techs will change your Century’s oil, replace and recycle your used oil and filter, check all of your other filters, refill vital car fluids, and visually inspect the rest of the vehicle. You can rest assured knowing that we seek to do what’s best for your Century by considering your driving style, and mileage.
Wondering if we carry the right motor oil for your Buick? We stock outstanding motor oils because that's what your engine deserves. Check your owner's manual and talk with a technician to select the right Buick Century oil, whether it's Quaker State® Advanced Durability™ conventional oil, Pennzoil® High Mileage Vehicle® motor oil, Pennzoil Platinum® Full Synthetic motor oil with PurePlus™ Technology, or Shell Rotella® heavy-duty engine oil. There's a reason we carry these motor oil brands. They are proven winners.

Most automobile manufacturers are expected to recommend oils that meet ILSAC GF-5. API SN is the most recent service category issued by API’s Lubricants Group. Oils meeting API SN and the new “Resource Conserving” designation meet all ILSAC GF-5 performance requirements.
