What can low oil do to my Mercedes-Benz S420 engine?

Engine oil is a lubricant for the moving parts in your engine. If your oil reservoir is low or empty, these parts can grind together, generate too much heat, and cause your Mercedes-Benz S420 engine to fail. That’s why it’s best to check your oil levels and get your oil changed regularly.

Can I change my Mercedes-Benz S420 oil at home?

First off, changing your own oil isn’t as easy as you’d think. It requires special tools and old oil must be disposed of properly. Having your oil professionally changed reduces the chances of something going wrong with the oil change, but it’ll also help your car perform smoothly down the road.

Does my S420's oil filter need to be changed during my oil change?

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.”

Mercedes-Benz recommends changing your 1999 S420’s oil at regular intervals. See mileage and month specifics in the above table. No matter the mileage, your S420 may need its oil changed ASAP if your check engine light is on, you hear engine knocking, smell oil inside the car, or see an excess amount of vehicle exhaust.

In general, being extra-diligent about oil changes won’t damage your Mercedes-Benz S420. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.
