When should Mercedes-Benz SL550 spark plugs be replaced?

Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on Mercedes-Benz’s recommendations.

What does a puddle underneath my Mercedes-Benz SL550 mean?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

Are hard starts and stops bad for my Mercedes-Benz SL550 engine?

You can make your driving habits more engine-friendly. Hard starts and stops can increase the stress on engine parts, especially over many years. Boost your fuel economy and care for your engine by using gradual, smooth starts and stops instead.

Enhance Mercedes-Benz SL550 Performance with a Tune-Up

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 2019 Mercedes-Benz SL550. Periodic tune-ups can bring more power back to your SL550’s engine. Tune-ups give your engine a boost in efficiency, so you can enjoy improved fuel economy and lower emissions. When you get routine engine tune-ups based on Mercedes-Benz's recommendations, you can rest assured you’re investing in your SL550’s long-term engine performance.

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. The result? Restored fuel system performance. Consider this when choosing a tune-up service for your SL550: your vehicle’s maintenance record and mileage can determine which service is best. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
