Need more info about 1985 Mercedes-Benz 300SD oil changes? Look no further than Firestone Complete Auto Care! We are experts in car care — not just tires. We know all about motor oil, too. After all, like our maintenance technician Brianna says, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”
Mercedes-Benz recommends having your 1985 Mercedes-Benz 300SD’s motor oil changed at regular intervals. Check the interval for your vehicle mileage in the table above. No matter the mileage, your 300SD may need its oil changed ASAP if your check engine light is on, you hear knocking sounds coming from the engine, sense an oil smell in the cabin, or notice excess vehicle exhaust. You might need an oil change more frequently than what’s recommended by Mercedes-Benz if you regularly haul heavy loads, frequent dusty roads, adventure off-road, or go long distances at low speeds. Generally, getting more frequent oil changes won’t hurt your Mercedes-Benz 300SD. In fact, every oil change is an opportunity to diagnose and treat any other issues, such as bad brakes or a failing battery.
Your local Firestone Complete Auto Care has the right 1985 Mercedes-Benz 300SD motor oil: either synthetic or conventional. Mercedes-Benz has specifically identified either synthetic or conventional as the ideal engine oil for your 1985 300SD. This oil helps lubricate engine parts, keep the engine cool, and prevent the build-up of harmful substances within the engine. During your oil change service, a technician will change your 300SD's oil, replace and recycle your used oil and filter, inspect the rest of your car’s filters, top-off essential fluids, and perform a free inspection on the rest of your vehicle. You can rest assured knowing that we seek to do what’s best for your 300SD by considering your driving style, local climate,
