What happens if my Mercedes-Benz S450 spark plugs fail?

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 S450?

Don't ignore puddles of fluid under your Mercedes-Benz S450. 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.

Are hard starts and stops bad for my Mercedes-Benz S450 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.
