When to Change 1991 Pontiac Bonneville Engine Oil

Not sure how or where to get your Pontiac Bonneville’s oil changed? Get the advice you need at Firestone Complete Auto Care! Our expertise goes beyond 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.

Pontiac recommends having your 1991 Pontiac Bonneville’s motor oil changed at regular intervals. Check the interval for your vehicle mileage in the table above. Outside of Pontiac-recommended oil change intervals, your Bonneville may need an oil change if your check engine light is on, you hear knock knock knock coming from the engine, smell oil inside the vehicle, or see an excess amount of vehicle exhaust. You may also need an oil change more frequently than Pontiac recommends if you haul heavy loads, drive in dusty areas, enjoy off-roading, or go at low speeds on long distance trips. In general, being extra-diligent about oil changes won’t damage your Pontiac Bonneville. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.

What’s the Right Type of Oil for 1991 Pontiac Bonneville?

Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your Pontiac Bonneville. Pontiac has most likely outlined either synthetic or conventional as the best oil for 1991 Pontiac Bonneville vehicles. Motor oil reduces friction between engine components, maintain proper engine temperature, and prevent harmful substances from accumulating in the engine. In an oil change service, one of our techs will change your Bonneville’s oil, replace and recycle your used oil and filter, inspect the rest of your car’s filters, top-off important fluids, and perform a free inspection on the rest of your vehicle. You can drive with confidence knowing that we look out for you and your Bonneville by taking into account your driving preferences, and odometer.

Oil Change Q&A for Your 1991 Pontiac Bonneville

  • Why check the motor oil level in my Pontiac Bonneville? Engine oil is a lubricant for the moving parts in your engine. If your oil runs low, these parts can grind together, overheat, and eventually lead to Pontiac Bonneville engine failure. That’s why it’s best to check your oil levels and get your oil changed regularly.
  • Can I change my Pontiac Bonneville oil at home? 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 changed professionally can not only reduce the risk of something going wrong during the service, but also help your car perform down the road.
  • Why is my Pontiac Bonneville spewing blue or gray exhaust smoke? You could have an oil leak and have a case of burning oil. It may be time for a pro to take a look. The leak could be caused by several issues like leaking valve seals, fried piston rings, or old cylinder walls.
