Will it hurt my Mercedes-Benz 300SD 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 does a puddle underneath my Mercedes-Benz 300SD mean?

Don't ignore puddles of fluid under your Mercedes-Benz 300SD. 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.

What do hard starts and stops do to my 300SD 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.

Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

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

Is it tune-up time? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you drive a 1984 Mercedes-Benz 300SD. Routine engine tune-ups can bring power back to your 300SD. Tune-ups help your engine start smoothly and run 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 300SD’s engine running smoother, longer.

Engine Tune-Up for Mercedes-Benz 300SD

The Firestone Complete Auto Care location in your community offers several Mercedes-Benz 300SD engine tune-up services. The first 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*. The second service focuses on your 300SD'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 300SD. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your 300SD: your vehicle’s maintenance record and mileage can determine which service is best. 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.
