Will it hurt my Mercedes-Benz G550 to drive with old spark plugs?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

What does a puddle underneath my Mercedes-Benz G550 mean?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

Are some driving habits better for my Mercedes-Benz G550 engine than others?

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.

Enhance Mercedes-Benz G550 Performance with a Tune-Up

Is your engine overdue for a tune-up? 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 2014 Mercedes-Benz G550’s engine to last for a long time. Periodic tune-ups can bring more power back to your G550’s engine. Tune-ups give your engine a boost in efficiency, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you follow the guidelines specified by Mercedes-Benz for your vehicle’s tune-up schedule, you’re taking vital steps toward keeping your G550’s engine running smoother, longer.

Engine Tune-Up for Mercedes-Benz G550

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2014 Mercedes-Benz G550. The first 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*. Another service option pays special attention to the filters in your G550. Specifically, we replace the fuel filter and air filter. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your G550’s fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your G550: 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. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Where Should I Go for My Mercedes-Benz G550 Tune-Up?

Come to Firestone Complete Auto Care for your next 2014 G550 engine tune-up. Follow Mercedes-Benz's recommended maintenance schedule or book an appointment as soon as you notice one of the following: decreased gas mileage, "rough" idling or stalling when stopped, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.
