1991 Mercedes-Benz 350SDL Oil Change Q&A

  • Should I check my Mercedes-Benz 350SDL motor oil level? Engine oil lubricates moving parts in your engine. If your oil runs low, engine parts can grind together, generate excess heat, and eventually lead to Mercedes-Benz 350SDL engine failure. That’s why it’s best to check your oil levels and get your oil 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 changed professionally can not only reduce the risk of something going wrong during the service, but it’ll also help your car perform smoothly down the road.
  • Why is my Mercedes-Benz 350SDL spewing blue or gray exhaust smoke? There could be an oil leak and your engine is burning oil. It may be time for a pro to take a look. A leak can be caused by a variety of issues including faulty valve seals, damaged piston rings, or old cylinder walls.
