Need more info about 1991 Cadillac DeVille oil changes? Turn to 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.

Your 1991 DeVille’s oil should be changed according to Cadillac’s recommended oil change intervals. Check the interval for your vehicle mileage in the table above. Your DeVille may need an oil change right away if your check engine/oil change light is on, you hear knocking sounds coming from the engine, smell oil inside the car, or see an excess amount of vehicle exhaust.

More frequent oil changes generally won't harm your Cadillac DeVille. In fact, more frequent oil changes give our technicians more opportunities to catch and alert you to any issues, like worn brake pads or a weak battery.
