What type of fuel should be used for the Mercedes-Benz CLA?
2 Answers
Mercedes-Benz CLA should use 98 octane fuel. Introduction to the Mercedes-Benz CLA-Class AMG: The Mercedes-Benz CLA AMG is the latest member of the AMG family, also known as the "most powerful mass-produced 2.0T four-cylinder car in history." Its large multi-spoke wheels and rear aerodynamic kit make this car look extremely dynamic. Introduction to Mercedes-AMG: Mercedes-AMG is a high-performance sub-brand of Mercedes-Benz, specializing in the development of high-performance vehicles. In the 1990s, AMG introduced classic models including the C36 AMG, E50 AMG, C43 AMG, and various versions of the "55" series after 1997.
The Mercedes-Benz CLA features a relatively advanced engine design with a high compression ratio, requiring fuel with good anti-knock properties. I've driven several Mercedes models, including the CLA, and always use 95-octane unleaded gasoline as it ensures smooth engine operation and prevents knocking issues. Occasionally using 92-octane is acceptable, but prolonged use may affect performance, such as sluggish acceleration or increased carbon buildup. The manual explicitly recommends 95-octane or higher, and you can confirm this by checking the label on the fuel filler cap. As a side note, higher octane gasoline has a higher octane rating and better anti-knock properties, making it suitable for high-compression engines. If you accidentally use the wrong fuel and the engine light comes on, drive to a service center immediately for inspection—don’t delay. Choosing reputable gas stations is also crucial, as low-quality fuel can cause even more damage.
