When should Mercedes-Benz SL550 spark plugs be replaced?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What do I do if I see a pool of liquid under my Mercedes-Benz SL550?

Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.

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

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.

How frequently do I need to get my Mercedes-Benz SL550 fuel injectors cleaned?

The frequency at which car fuel injectors should be cleaned can vary depending on several factors, including the type of fuel used and the driving conditions. Some manufacturers generally recommend a fuel system cleaning as part of your general car maintenance, or as needed based on symptoms of poor fuel system performance.

Enhance Mercedes-Benz SL550 Performance with a Tune-Up

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it could be time for a new way of doing things, especially if you want your 2018 Mercedes-Benz SL550’s engine to last for a long time. Regular engine tune-ups can optimize your SL550’s power on the road. They're designed to help your engine start easier and run more efficiently, so you can enjoy improved fuel economy and lower emissions. When you follow the guidelines specified by Mercedes-Benz for your vehicle’s tune-up schedule, you’re taking vital steps toward keeping your SL550’s engine running smoother, longer.

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

The Firestone Complete Auto Care location in your community offers several Mercedes-Benz SL550 engine tune-up services. The standard Firestone Tune-Up is one service option. 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. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your SL550’s fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s 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.

Where Should I Go for My Mercedes-Benz SL550 Tune-Up?
