Will it hurt my Mercedes-Benz 300SEL to drive with old spark plugs?

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 300SEL?

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 some driving habits better for my Mercedes-Benz 300SEL engine than others?

Hard starts and stops put extra wear and tear on engine components. Smooth, gradual starts and stops, on the other hand, are a great way to help your engine run better. They can also help maximize your fuel economy.

Enhance Mercedes-Benz 300SEL Performance with a Tune-Up

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, especially if you drive a 1990 Mercedes-Benz 300SEL. Periodic tune-ups can bring more power back to your 300SEL’s engine. They're designed to help your engine start easier and run more efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you get routine engine tune-ups based on Mercedes-Benz's recommendations, you’re taking vital steps toward keeping your 300SEL’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Mercedes-Benz 300SEL

The Firestone Complete Auto Care location in your community offers several Mercedes-Benz 300SEL engine tune-up services. The first is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. The second service focuses on your 300SEL's filters, specifically replacing the air filter and fuel 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 300SEL. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your 300SEL: 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.
