1987 Mercedes-Benz 300SDL Engine Tune-Ups & Maintenance

Tune Into Your Mercedes-Benz 300SDL

Is it time for an engine tune-up? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you drive a 1987 Mercedes-Benz 300SDL. Routine engine tune-ups can bring power back to your 300SDL. They're designed to help your engine start easier and run more efficiently, so you can enjoy improved fuel economy and lower emissions. When you follow the guidelines specified by Mercedes-Benz for your vehicle’s tune-up schedule, you can rest assured you’re investing in your 300SDL’s long-term engine performance.

Engine Tune-Up for Mercedes-Benz 300SDL

The Firestone Complete Auto Care location in your community offers several Mercedes-Benz 300SDL engine tune-up services. One option 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 300SDL'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 300SDL. The result? Restored fuel system performance. Keep in mind that your 300SDL'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.

Common Engine Tune-Up Q&A For 1987 Mercedes-Benz 300SDLs

  • Will it hurt my Mercedes-Benz 300SDL to drive with old spark plugs? 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 300SDL? 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 300SDL 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.
