When should Mercedes-Benz S550 spark plugs be replaced?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

What should I do if I see leaks under my S550?

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 S550 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.

Tune-Ups to Help Your Mercedes-Benz S550 Run Better

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, especially if you drive a 2008 Mercedes-Benz S550. Routine engine tune-ups can bring power back to your S550. Tune-ups help your engine start smoothly and run efficiently, so you can enjoy improved fuel economy and lower emissions.

Mercedes-Benz S550 Engine Tune-Up Services

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2008 Mercedes-Benz S550. The standard Firestone Tune-Up is one service option. 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 S550. 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 S550’s fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your S550: your vehicle’s maintenance record and mileage can determine which service is best. If you’re not sure what services are the best fit for your car, let us help! Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
