How Often to Get 1991 Pontiac Grand Prix Oil Changes

Not sure how or where to get your Pontiac Grand Prix’s oil changed? Look no further than Firestone Complete Auto Care! We are experts in car care — not just 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.

Your 1991 Grand Prix’s oil should be changed according to Pontiac’s recommended oil change intervals. See mileage and month specifics in the above table. Outside of Pontiac-recommended oil change intervals, your Grand Prix may need an oil change if your check engine light is on, you hear engine knocking, smell oil inside the car, 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, go off-roading a lot, or go at low speeds on long distance trips. In general, being extra-diligent about oil changes won’t damage your Pontiac Grand Prix. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.

1991 Pontiac Grand Prix Oil Change Q&A

  • Should I check my Pontiac Grand Prix motor oil level? Engine oil lubricates moving parts in your engine. If your oil reservoir is low or empty, engine parts can grind together, generate excess heat, and cause your Pontiac Grand Prix engine to fail. That’s why you should check your oil and get it changed regularly.
  • Can I change my Pontiac oil on my own? First off, changing your own oil isn’t as easy as you’d think. 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 Grand Prix exhaust smoke grayish or blue? Your engine could be burning oil due to a leak. It may be time for a pro to take a look. The leak could be the result of worn valve seals, fried piston rings, or old cylinder walls.
