Should I check my Mercedes-Benz 300SL motor oil level?

Engine oil lubricates moving parts in your engine. If you're low or out of oil, these parts can grind together, generate too much heat, and cause your Mercedes-Benz 300SL engine to fail. That’s why you should check your oil and get it changed regularly.

Can I change my Mercedes-Benz oil on my own?

Changing your own oil isn't as convenient as you might 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 also help your car perform down the road.

Why is my Mercedes-Benz 300SL exhaust smoke grayish or blue?

You could have an oil leak and have a case of burning oil. It may be time for a pro to take a look. The leak could be the result of worn valve seals, blown piston rings, or worn cylinder walls.
