Oil Changes for 1986 Cadillac DeVille

Not sure how or where to get your Cadillac DeVille’s oil changed? Turn to Firestone Complete Auto Care! We are experts in car care — not just 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.

Cadillac recommends changing your 1986 DeVille’s oil at regular intervals. See mileage and month specifics in the above table. Outside of Cadillac-recommended oil change intervals, your DeVille may need an oil change if your check engine light is on, you hear knock knock knock coming from the engine, sense an oil smell in the cabin, or notice excess vehicle exhaust. You might need an oil change more frequently than what’s recommended by Cadillac if you regularly haul heavy loads, drive in dusty terrain, enjoy off-roading, or drive at low speeds for long distances. 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.

Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your Cadillac DeVille. Cadillac has specifically identified either synthetic or conventional as the best motor oil for your 1986 DeVille. This oil helps lubricate engine parts, maintain proper engine temperature, and keep harmful substances from building up inside the engine. In an oil change service, an auto technician will change your DeVille’s oil, replace and recycle the old oil and filter, inspect all of your other filters, top-off important fluids, and perform a courtesy inspection on your entire vehicle. You can rest assured knowing that we seek to do what’s best for your DeVille by considering your driving habits, and mileage.
