Why check the motor oil level in my Mercedes-Benz 300D?

Engine oil lubricates moving parts in your engine. If you're low or out of oil, engine parts can grind together, generate too much heat, and cause your Mercedes-Benz 300D engine to fail. That’s why you’re better off checking your oil levels and investing in routine lube services.

Can I change my Mercedes-Benz 300D oil at home?

Changing engine oil at home isn’t as simple as it’s made out to be. 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 also with your vehicle down the road.
