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.
  • Where can I get Mercedes-Benz 350SDL oil changes? Turn to Firestone Complete Auto Care for Mercedes-Benz 350SDL oil changes. In addition to changing your oil, our experienced technicians also perform oil filter replacements, troubleshoot oil leaks, and suggest the correct oil to help keep your engine performing its best.
  • What does it mean if my Mercedes-Benz 350SDL oil light comes on? Your Mercedes-Benz 350SDL oil change reminder light might illuminate if it’s been too long since your last oil change. On the other hand, the oil pressure light might illuminate due to a clogged oil filter, a faulty oil pressure sensor, low engine oil levels, or a malfunctioning oil pump.
  • Should the oil filter be replaced when getting an oil change for my Mercedes-Benz 350SDL? You should replace your Mercedes-Benz 350SDL during each oil change. The filter captures debris and contaminants to help keep your oil clean, which means the filter gets dirty. If you skip replacing the filter, you’ll contaminate your new oil with the dirty filter.
