They say you get out of life what you put into it. This is also true of a powerful, luxurious new Mercedes-Benz. For the best performance and reliability, be sure you're using the right fuel for your car! When you put the right fuel inside, you'll enjoy the exciting driving experience Mercedes-Benz is known for. Over time, using low-quality fuels or the incorrect grade can cause damage to the vehicle's fuel delivery system. Find out more in the details below.
Because of their high compression ratios to achieve the most enthusiastic acceleration and performance, the engines in Mercedes-Benz vehicles typically require premium gas. But what is premium gas? With its higher octane rating, premium fuels are more stable. They resist early combustion, detonating in a single flame front at the moment the spark plug ignites a spark inside the engine's cylinders. Were you to use regular unleaded fuel, the fuel can begin to combust too early from sheer compression. These early combustion events can make knocking or pinging noises from the engine. Over time, this engine knock can do damage to the engine. Worse, you're likely to get less power and poor fuel economy.
In addition to choosing the right grade of fuel for your car, it's important to avoid contaminated gasoline. While most any gasoline that's legal to sell in the United States is of a sufficient quality for your Mercedes-Benz, the most common problem with gasoline is water contamination. Fuel is stored in underground tanks beneath the gas station. If they're not properly maintained, rain water could potentially leach into the tanks. If a particular filling station is looking run down and lacking in upkeep, you may want to drive on to a different one. For the best quality gasoline, look for Top Tier Gas, available from most major filling station brands in Southern California.
In general, as long as you're using the right fuel, your fuel system won't need much if any maintenance. As part of your scheduled Mercedes-Benz maintenance, a technician will inspect your vehicle to ensure the continued performance and efficiency you expect. Most modern Mercedes-Benz vehicles also have a fuel filter that will need to be replaced at 150,000 miles. If you experience poor fuel economy or sluggish performance, we may also recommend a deep-clean of the fuel system, including the fuel injectors, to remove any build-up that can disrupt flow in the system.
Perhaps the trouble you're having isn't related to the fuel system itself, but a related component? For example, even something like a clogged engine air filter can affect fuel efficiency and performance. The right ratio of air to fuel keeps your engine running its best, but if you have a bad air filter, bad mass airflow sensor or bad throttle body, too much or too little air might be making it to the engine. Or, you might have leaking fuel lines or fuel injectors. No matter what the case may be, the place to go in Southern California to get your Mercedes-Benz fixed is our state-of-the-art service center.
