What Octane Gasoline Should a Mercedes-Benz Use?

Mercedes-Benz vehicles require a minimum of 95 octane gasoline, while high-performance AMG models need 98 octane gasoline. Different octane ratings indicate varying levels of octane numbers, with higher ratings corresponding to better stability. Most cars equipped with turbocharged engines require high-octane gasoline. The Mercedes-Benz aerotrailer, for example, features a significantly different design compared to traditional trailers. It incorporates a front air dam, side skirts, and a rear trapezoidal spoiler for aerodynamic efficiency, along with a tapered rear compartment design aimed at reducing wind resistance.

Mercedes owners all know that my car requires 91 octane or higher fuel, as clearly stated in the manual. Mercedes engines are precision-designed, and higher octane fuel prevents knocking, improves combustion efficiency, and protects the engine. For my C-Class, I always use Premium fuel. While you can occasionally save money by using lower 89 octane, it's not good for the engine long-term. Last time I tried regular fuel, I immediately noticed sluggish acceleration and faint abnormal noises, so I switched back promptly. Always check your fuel cap or owner's manual - requirements may vary by model year, and high-performance AMG models may need 95 octane or higher. Don't cut corners on fuel quality for daily maintenance. Regular fuel system checks will save you headaches and money in the long run.

As an enthusiast who frequently interacts with various cars, I recommend Mercedes-Benz owners to consistently use high-octane gasoline, such as 91 or 93 octane. The reason is simple: Mercedes-Benz engines are designed with a high compression ratio, and low-octane fuel is prone to pre-ignition, leading to knocking and reduced power output. I've seen cases where long-term use of low-octane fuel increased carbon deposits in the engine, resulting in higher repair costs. Different models have varying requirements: basic models usually only need 91 octane, while S-Class or AMG versions may require 95 octane. There is usually a label inside the fuel tank cap as a reminder, so make it a habit to check before each refueling. A fuel-saving tip is to regularly maintain the air filter to keep the engine running more efficiently.

My Mercedes-Benz GLC uses 91-octane gasoline, and the manual recommends Premium grade. Engine performance relies on high-quality fuel, and lower-octane gasoline may cause minor issues such as shaking and slow acceleration. When refueling, I choose reputable gas stations to ensure fuel purity. In daily use, I avoid randomly switching gasoline grades to maintain consistency, which is better for the car.

Years of driving Mercedes-Benz have taught me that using fuel with an octane rating of 91 or above is essential, with Premium being the standard. While lower-grade fuel may save money in the short term, the high compression ratio of the engine makes it prone to knocking, which can shorten its lifespan. Always check the fuel cap instructions before refueling; developing good habits like regular maintenance can help prevent malfunctions.
