When should Mercedes-Benz 300D spark plugs be replaced?

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 should I do if I see leaks under my 300D?

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.

Are hard starts and stops bad for my Mercedes-Benz 300D engine?

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 300D Performance with a Tune-Up

Is it tune-up time? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, especially if you want your 1987 Mercedes-Benz 300D’s engine to last for a long time. Regular engine tune-ups can optimize your 300D’s power on the road. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by Mercedes-Benz, you can rest assured you’re investing in your 300D’s long-term engine performance.

Engine Tune-Up for Mercedes-Benz 300D

The Firestone Complete Auto Care location in your community offers several Mercedes-Benz 300D engine tune-up services. One option is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. The second service focuses on your 300D's filters, specifically replacing the air filter and fuel filter. 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 300D's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your 300D's mileage and maintenance history can uniquely impact its tune-up needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
