How Often to Get 2021 Mercedes-Benz CLS450 Oil Changes

Looking for oil change recommendations for your 2021 Mercedes-Benz CLS450? Turn to 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.

Mercedes-Benz recommends having your 2021 Mercedes-Benz CLS450’s motor oil changed at regular intervals. Check the interval for your vehicle mileage in the table above. Outside of Mercedes-Benz-recommended oil change intervals, your CLS450 may need an oil change if your check engine light is on, you hear knocking sounds coming from the engine, smell oil inside the car, or notice an unusual amount of exhaust. You might need an oil change more frequently than what’s recommended by Mercedes-Benz if you regularly haul heavy loads, drive in dusty areas, enjoy off-roading, or go long distances at low speeds. Generally, getting more frequent oil changes won’t hurt your Mercedes-Benz CLS450. 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.

What Type of Oil Does My Mercedes-Benz CLS450 Need?

Your local Firestone Complete Auto Care has the right 2021 Mercedes-Benz CLS450 motor oil: either synthetic or conventional. Mercedes-Benz has specifically identified either synthetic or conventional as the ideal engine oil for your 2021 CLS450. Motor oil reduces friction between engine components, maintain proper engine temperature, and keep harmful substances from building up inside the engine. During an oil change, one of our techs will change your CLS450’s oil, replace and recycle the old oil and filter, inspect the rest of your car’s filters, top-off essential 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 CLS450 by considering your driving habits, and mileage.

2021 Mercedes-Benz CLS450 Oil Change Q&A

  • What can low oil do to my Mercedes-Benz CLS450 engine? Motor oil lubricates important engine parts.

That’s why it’s best to check your oil levels and get your oil changed regularly.
  • How hard is it to change Mercedes-Benz CLS450 oil at home? 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 also with your vehicle down the road.
  • Why is my Mercedes-Benz exhaust smoke gray or blue? Your engine could be burning oil due to a leak. Time to have a qualified technician check things out. The leak could be the result of worn valve seals, blown piston rings, or worn cylinder walls.
