How Often to Get 2005 Cadillac STS Oil Changes

Not sure how or where to get your Cadillac STS’s oil changed? Look no further than Firestone Complete Auto Care! Our expertise goes beyond tires. We know the ins and outs of motor oil, too. After all, like our maintenance technician Brianna says, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”

Cadillac recommends having your 2005 Cadillac STS’s motor oil changed at regular intervals. Check out mileage and month info for your STS in the above table. No matter the mileage, your STS 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 an unusual amount of exhaust. You may also need an oil change more frequently than Cadillac recommends if you haul heavy loads, frequent dusty roads, enjoy off-roading, or go long distances at low speeds. More frequent oil changes generally won't harm your Cadillac STS. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.

Getting a professional oil change reduces the risk of something going wrong during the service, but also help your car perform down the road.
  • Why is my Cadillac STS exhaust smoke grayish or blue? Your engine could be burning oil due to a leak. Looks like it’s time for a professional to take a look. The leak could be caused by several issues like leaking valve seals, damaged piston rings, or old cylinder walls.
