Need more info about 1989 Mercedes-Benz 420SEL oil changes? Turn to Firestone Complete Auto Care! Our expertise goes beyond 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 1989 Mercedes-Benz 420SEL’s motor oil changed at regular intervals. See mileage and month specifics in the above table. No matter the mileage, your 420SEL 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 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, go off-roading a lot, or drive at low speeds for long distances. Generally, getting more frequent oil changes won’t hurt your Mercedes-Benz 420SEL. In fact, more frequent oil changes give our technicians more opportunities to catch and alert you to any issues, like worn brake pads or a weak battery.
Your local Firestone Complete Auto Care has the right 1989 Mercedes-Benz 420SEL motor oil: either synthetic or conventional. Mercedes-Benz has recommendations as to whether conventional or synthetic oil is the best motor oil for your 1989 420SEL. Motor oil helps lubricate the engine’s moving parts, keep the engine cool, and prevent the build-up of harmful substances within the engine. In an oil change service, a technician will change your 420SEL's oil, replace and recycle your used oil and oil filter, inspect all of your other filters, refill vital car 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 420SEL by considering your driving preferences, and mileage.
