Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, particularly if you want to keep your 2015 Mercedes-Benz SL550 in tip-top shape. Routine engine tune-ups can bring power back to your SL550. Tune-ups help your engine start smoothly and run efficiently, so you can enjoy improved fuel economy and lower emissions.

Routine Engine Tune-Up Service for Your Mercedes-Benz SL550

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz SL550 engine tune-up services. One option is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. Another service option pays special attention to the filters in your SL550. Specifically, we replace the fuel filter and air filter. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your SL550. This goes a long way in boosting your fuel system’s overall performance. Here’s something to remember when choosing services: the mileage and service history of your SL550 can determine what kind of service it 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.
