Is it time for an engine tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, now is the time to work on that habit, especially if you drive a 1991 Mercedes-Benz 420SEL. Regular engine tune-ups can optimize your 420SEL’s power on the road. Tune-ups help your engine start smoothly and run efficiently, so you can enjoy improved fuel economy and lower emissions. When you take your car for regular engine tune-ups as recommended by Mercedes-Benz, you’re taking vital steps toward keeping your 420SEL’s engine running smoother, longer.
Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1991 Mercedes-Benz 420SEL. The first is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. A second service option replaces the air and fuel filter in your 420SEL. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your 420SEL's fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your 420SEL's mileage and maintenance history can uniquely impact its tune-up needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
If you’re looking for 1991 420SEL engine tune-up services, head to Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Mercedes-Benz, or make a service appointment if you notice any of these symptoms from your engine: decreased gas mileage, "rough" idling or stalling when stopped, knocking noises in the engine, or a lit up check engine light on your dashboard.
