When to Change 1991 Oldsmobile 98 Engine Oil

Need more info about 1991 Oldsmobile 98 oil changes? Look no further than Firestone Complete Auto Care! Our expertise goes beyond tires. We know all about 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.

Oldsmobile recommends having your 1991 Oldsmobile 98’s motor oil changed at regular intervals. See mileage and month specifics in the above table. Outside of Oldsmobile-recommended oil change intervals, your 98 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 car, or notice excess vehicle exhaust. You might need an oil change more frequently than what’s recommended by Oldsmobile if you regularly haul heavy loads, frequent dusty roads, go off-roading a lot, or go long distances at low speeds. In general, being extra-diligent about oil changes won’t damage your Oldsmobile 98. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.

1991 Oldsmobile 98 Oil Change Q&A

  • What can low oil do to my Oldsmobile 98 engine? Engine oil lubricates moving parts in your engine. If your oil reservoir is low or empty, these parts can grind together, generate excess heat, and eventually lead to Oldsmobile 98 engine failure. That’s why it’s best to check your oil levels and get your oil changed regularly.
  • Can I change my Oldsmobile 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. Getting a professional oil change reduces the risk of something going wrong during the service, but it’ll also help your car perform smoothly down the road.
  • Why is my Oldsmobile 98 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, fried piston rings, or old cylinder walls.
