Looking for oil change recommendations for your 1991 Mercedes-Benz 300D? Turn to Firestone Complete Auto Care! Our expertise goes beyond tires. Oil and lube services are also our specialties. We couldn’t put it better than our technician, Brianna. She likes to explain to customers that, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”

Mercedes-Benz recommends changing your 1991 300D’s oil at regular intervals. Check the interval for your vehicle mileage in the table above. No matter the mileage, your 300D may need its oil changed ASAP if your check engine light is on, you hear engine knocking, sense an oil smell in the cabin, or notice excess vehicle exhaust. You may also need an oil change more frequently than Mercedes-Benz recommends if you haul heavy loads, drive in dusty areas, enjoy off-roading, or drive at low speeds for long distances. In general, being extra-diligent about oil changes won’t damage your Mercedes-Benz 300D. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.

Oil Change Q&A for Your 1991 Mercedes-Benz 300D

  • 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.
  • Why is my Mercedes-Benz exhaust smoke gray or blue? Your engine could be burning oil due to a leak. Looks like it’s time for a professional to take a look. The leak could be the result of worn valve seals, damaged piston rings, or worn cylinder walls.
  • Who can change the oil on my Mercedes-Benz 300D? You can count on Firestone Complete Auto Care for your Mercedes-Benz 300D oil change, oil filter replacement, oil leak diagnostics, and more! Our expert technicians will even advise the right oil for your vehicle.
  • What can cause the oil light on my Mercedes-Benz 300D to illuminate? Your Mercedes-Benz 300D oil change reminder light may come on if you're overdue for an oil change. The oil pressure light will typically come on if the oil level in the engine is too low, the oil pump is failing, you have a clogged oil filter, or there's a faulty oil pressure sensor.
  • Do I need to change my 300D's oil filter when I get an oil change? It's recommended that you replace your Mercedes-Benz 300D oil filter with every oil change. Otherwise, you send fresh, clean motor oil through a dirty filter. That's like putting on muddy socks after a shower.
