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

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What should I do if I see leaks under my 300TD?

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 300TD 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.
