What grade of fuel should be used for the Mercedes-Benz CLA45?
2 Answers
All models of the Mercedes-Benz CLA class require a minimum of 95-octane fuel. Function of Engine Oil: Engine oil serves to lubricate and reduce friction in the engine, assist in cooling, provide sealing to prevent leaks, protect against rust and corrosion, and act as a shock absorber. It is often referred to as the 'blood' of the car. Choosing the right engine oil and changing it regularly can maintain the engine in good condition and extend its lifespan. Choosing Engine Oil: When selecting engine oil, the most expensive option isn't necessarily the best. Instead, the right choice should be based on the characteristics of the car's engine and the driver's usual driving habits. Engine oil can be categorized based on its use in winter or summer. For winter, the primary consideration is the low-temperature viscosity grade, while in summer, due to higher temperatures, there's no need to select an oil with an excellent low-temperature viscosity grade.
I'm the owner of a Mercedes-Benz CLA45, and this car has impressive performance, but you have to be particular about the fuel. The manufacturer recommends using 98-octane unleaded gasoline because of its high octane rating, which prevents engine knocking at high RPMs. Knocking might sound scary, but it's essentially premature ignition of the fuel, causing the car to jerk like it's hiccupping, and prolonged knocking can damage the engine. The Mercedes-Benz CLA45 is the AMG version, with highly tuned power, making the engine particularly sensitive to fuel quality. I always refuel at major gas stations like Sinopec or Shell to ensure clean fuel. If you can't find 98-octane in remote areas, 95-octane can work in a pinch, but it's best not to use it long-term, as it can lead to higher fuel consumption, sluggish acceleration, and a soft throttle response. Adding a bottle of fuel system cleaner periodically helps maintain the fuel system and avoids trips to the repair shop—safety first, after all. In short, high-performance cars require high-octane fuel; spending a bit more ensures smooth engine operation and longevity.
