It’s the #1 thing you can do for your car.”
Your 1991 350SDL’s oil should be changed according to Mercedes-Benz’s recommended oil change intervals. Check out mileage and month info for your 350SDL in the above table. Your 350SDL may need an oil change right away if your check engine/oil change light is on, you hear engine knocking, sense an oil smell in the cabin, 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, frequent dusty roads, enjoy off-roading, or go long distances at low speeds. More frequent oil changes generally won't harm your Mercedes-Benz 350SDL. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.
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 recommendations as to whether conventional or synthetic oil is the ideal engine oil for your 1991 350SDL. This oil helps lubricate engine parts, maintain proper engine temperature, and prevent the build-up of harmful substances within the engine.
