What happens if my Mercedes-Benz SL550 spark plugs fail?

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 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.

What do hard starts and stops do to my 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 often do Mercedes-Benz SL550 fuel injectors need to be cleaned?

There is no hard and fast rule on how often fuel injectors should be cleaned, and it can vary based on driving habits and fuel type. Some manufacturers may suggest including a fuel system cleaning in your regular maintenance schedule. Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Tune Into Your Mercedes-Benz SL550

Is it tune-up time? If you're the type of driver who waits for something to go wrong with your vehicle, it might be time to change your ways, particularly if you want to keep your 2012 Mercedes-Benz SL550 in tip-top shape. Routine engine tune-ups can bring power back to your SL550. Tune-ups give your engine a boost in efficiency, 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 SL550’s engine running smoother, longer.

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. The first is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. A second service option replaces the air and fuel filter in your SL550. 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 can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your SL550's mileage and maintenance history can uniquely impact its tune-up needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.
