How Often to Get 1991 Buick Century Oil Changes

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.

What Type of Oil Does My Buick Century Need?

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.

1991 Buick Century Oil Change Q&A

  • Should I check my Buick Century motor oil level? Engine oil is a lubricant for the moving parts in your engine. If your oil runs low, these components can grind against each other, overheat, and eventually lead to Buick Century engine failure. That’s why it’s best to check your oil levels and get your oil changed regularly.
  • Can I change my Buick oil on my own? Changing engine oil at home isn’t as simple as it’s made out to be. You’ll have to buy special tools and figure out a way to recycle the old oil properly. Having your oil professionally changed reduces the chances of something going wrong with the oil change, but also with your vehicle down the road.
  • Why is my Buick Century exhaust smoke grayish or blue? There could be an oil leak and your engine is burning oil. Looks like it’s time for a professional to take a look. The leak could be the result of worn valve seals, blown piston rings, or worn cylinder walls.
