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.
Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your Mercedes-Benz 300D. Mercedes-Benz has specifically identified either synthetic or conventional as the ideal engine oil for your 1991 300D. Motor oil helps lubricate the engine’s moving parts, keep the engine cool, and keep harmful substances from building up inside the engine. During your oil change service, a technician will change your 300D's oil, replace and recycle the old oil and filter, check all of your other filters, top-off important fluids, and visually inspect the rest of the vehicle. You can rest assured knowing that we seek to do what’s best for your 300D by considering your driving habits, climate,
