What happens if my Mercedes-Benz S450 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 does a puddle underneath my Mercedes-Benz S450 mean?

Don't ignore puddles of fluid under your Mercedes-Benz S450. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.

Are hard starts and stops bad for my Mercedes-Benz S450 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.

Enhance Mercedes-Benz S450 Performance with a Tune-Up

Is your engine overdue for a tune-up? 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, especially if you drive a 2020 Mercedes-Benz S450. Periodic tune-ups can bring more power back to your S450’s engine. Tune-ups give your engine a boost in efficiency, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you follow the guidelines specified by Mercedes-Benz for your vehicle’s tune-up schedule, you invest in your S450's long-term health and engine performance.

Engine Tune-Up for Mercedes-Benz S450

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz S450 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*. A second service option replaces the air and fuel filter in your S450. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your S450'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 S450 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. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Where to Get a Tune-Up for Your Mercedes-Benz S450
