Oldsmobile recommends having your 1991 Oldsmobile Delta 88’s motor oil changed at regular intervals. Check out mileage and month info for your Delta 88 in the above table. No matter the mileage, your Delta 88 may need its oil changed ASAP if your check engine light is on, you hear knock knock knock coming from the engine, smell oil inside the vehicle, 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, enjoy off-roading, or go at low speeds on long distance trips. In general, being extra-diligent about oil changes won’t damage your Oldsmobile Delta 88. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.

1991 Oldsmobile Delta 88 Oil Change Questions

  • Why check the motor oil level in my Oldsmobile Delta 88? Engine oil is a lubricant for the moving parts in your engine. If your oil runs low, engine parts can grind together, generate excess heat, and cause your Delta 88’s engine to fail. That’s why you should check your oil and get it changed regularly.
  • Can I change my Oldsmobile oil on my own? Changing your own oil isn't as convenient as you might think. You’ll have to figure out how to properly dispose of the oil and buy special tools. 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 Oldsmobile Delta 88 exhaust smoke grayish or blue? There could be an oil leak and your engine is burning oil. It may be time for a pro to take a look. The leak could be the result of worn valve seals, damaged piston rings, or damaged cylinder walls.
