What kind of fuel should be used for the Mercedes-Benz E300?
2 Answers
Mercedes-Benz E300 manufacturer requires the use of 95-octane or higher gasoline that meets national standards. In fact, the Mercedes-Benz E-Class can use either 92-octane or 98-octane gasoline. From the perspective of fuel economy, there is not much difference between the two. Actually, for a car like the Mercedes-Benz E-Class, there is really no need to use 98-octane gasoline; 95-octane is sufficient, and using a higher octane rating may not be beneficial. Below is the relevant introduction: 1. Octane rating: Although higher octane gasoline has better anti-knock performance, it does not mean that the highest 98-octane gasoline is suitable for all cars. If the engine is designed to use a minimum octane rating of 95, then 98-octane gasoline can also be used. 2. Impact of excessively high octane rating: For example, the Mercedes-Benz E-Class is designed for a minimum of 95-octane. Using 98-octane gasoline may result in incomplete combustion of the fuel, which not only wastes the energy in the fuel but also increases carbon deposits.
After driving the Mercedes-Benz E300 for so many years, I've concluded that fuel quality is truly crucial. This car should be filled with 95 or 98 octane gasoline, and never opt for 92 octane to save money, as it may cause engine knocking, reduced power, and significant long-term damage. I personally tried lower-octane fuel a few times and experienced noticeable acceleration hesitation. Later, I consistently used 95 octane or higher, and the car's performance returned to smooth operation. The Mercedes official manual also emphasizes that higher-octane fuel improves combustion efficiency and reduces carbon buildup. Regularly check the oil pressure after refueling to ensure it's within the normal range, and be extra careful before long trips. Choose reputable gas stations to ensure fuel purity, making your drive both safe and comfortable.
