Will it hurt my Mercedes-Benz SL43 AMG 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 should I do if I see leaks under my SL43 AMG?

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 SL43 AMG 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.

There is no hard and fast rule on how often fuel injectors should be cleaned, and it can vary based on driving habits and fuel type. Some manufacturers may suggest including a fuel system cleaning in your regular maintenance schedule. Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Tune-Ups to Help Your Mercedes-Benz SL43 AMG Run Better

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, now is the time to work on that habit, especially if you want your 2024 Mercedes-Benz SL43 AMG’s engine to last for a long time. Routine engine tune-ups can bring power back to your SL43 AMG. 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 invest in your SL43 AMG's long-term health and engine performance.

Routine Engine Tune-Up Service for Your Mercedes-Benz SL43 AMG

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercedes-Benz SL43 AMG engine tune-up services. The standard Firestone Tune-Up is one service option. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. Another service option pays special attention to the filters in your SL43 AMG. Specifically, we replace the fuel filter and air 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 SL43 AMG. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your SL43 AMG: your vehicle’s maintenance record and mileage can determine which service is best. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

Where to Get a Tune-Up for Your Mercedes-Benz SL43 AMG

If you’re looking for 2024 SL43 AMG engine tune-up services, head to Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Mercedes-Benz, or make a service appointment if you notice any of these symptoms from your engine: shaking while the engine is idling, poor fuel economy, engine knocking, or an illuminated check engine light.
