Mercedes-Benz recommends having your 1990 Mercedes-Benz 350SDL’s motor oil changed at regular intervals. Check the interval for your vehicle mileage in the table above. Outside of Mercedes-Benz-recommended oil change intervals, your 350SDL may need an oil change if your check engine light is on, you hear knock knock knock coming from the engine, smell oil inside the vehicle, or notice an unusual amount of exhaust. You may also need an oil change more frequently than Mercedes-Benz recommends if you haul heavy loads, drive in dusty areas, go off-roading a lot, or drive at low speeds for long distances. More frequent oil changes generally won't harm your Mercedes-Benz 350SDL. 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 350SDL. Mercedes-Benz has specifically identified either synthetic or conventional as the best oil for 1990 Mercedes-Benz 350SDL vehicles. Motor oil reduces friction between engine components, maintain proper engine temperature, and prevent the build-up of harmful substances within the engine. In an oil change service, an auto technician will change your 350SDL’s oil, replace and recycle the old oil and filter, check all of your other filters, top-off important fluids, and perform a free inspection on the rest of your vehicle. You can drive with confidence knowing that we look out for you and your 350SDL by taking into account your driving habits, local climate,
