What type of gasoline should a Mercedes-Benz S350 use?
2 Answers
The Mercedes-Benz S350 should use 95-octane gasoline. Gasoline standard selection: The engine compression ratio is the sole criterion for selecting the appropriate gasoline grade. Vehicles with a compression ratio between 8.0 and 8.5 should use 92 or 95-octane gasoline; those between 8.5 and 9.5 should use 95-octane or higher gasoline; and vehicles with a compression ratio above 9.5 should use 97 or 98-octane gasoline. Introduction to the Mercedes-Benz S-Class: The Mercedes-Benz S-Class is a top-tier luxury vehicle produced by the German Daimler Group under the Mercedes-Benz brand. The S-Class features bi-xenon headlights, with distinctive turn signals that enhance visibility. The uniquely styled taillights add a dynamic touch, and the use of striking LED technology for the turn signals, taillights, and brake lights creates a unique visual signature.
When I drive my Mercedes S350, I usually fill it with 95-octane unleaded gasoline, and the engine runs very smoothly. The Mercedes manual recommends 95 or 98-octane fuel because the engine has a high compression ratio, and higher-octane fuel prevents knocking, which sounds like a tapping noise that can damage the engine. In China, 95-octane is common and practical—don’t try to save money by using 92-octane. Once, I accidentally filled up with the wrong fuel, and the car shook badly. I had to drain the tank and switch back to 95-octane. New car owners should always follow the manufacturer’s recommendations. Using the right fuel long-term protects the engine, avoids repair hassles, and reduces safety risks—all the details are in the manual.
