What type of fuel should a Mercedes-Benz GLA200 use?
2 Answers
Mercedes-Benz GLA200 cars should use 95-octane gasoline. Here is the relevant introduction: Generally, high-performance vehicles like the Mercedes-Benz GLA200 coupe use 95-octane gasoline. The engines of the Mercedes-Benz GLA that use 92-octane and 95-octane fuels have different compression ratios. Additionally, the two types of fuel have different octane ratings and combustion speeds. The higher the fuel grade, the slower the combustion speed and the lower the combustion knock, requiring a higher engine compression ratio. Conversely, lower-grade fuel burns faster with higher combustion knock, requiring a lower engine compression ratio. Lower-grade gasoline burns faster, requiring a delayed ignition angle, while higher-grade fuel burns slower, requiring an advanced ignition angle.
This Mercedes-Benz GLA200 is best fueled with 95-octane gasoline due to its high engine compression ratio. Using 92-octane fuel can easily cause knocking and damage the engine—I personally experienced the consequences of using the wrong fuel, which resulted in severe engine shaking and costly repairs. Always check the fuel cap or manual for the recommended octane rating, which specifies 95 or higher. If you're traveling and can't find 95-octane fuel, you can add some fuel additives as a temporary measure, but don't compromise long-term, as it will lead to increased fuel consumption and reduced performance. From the very beginning, develop good habits with your new car—don't risk damaging its heart just to save a few cents.
