What type of fuel should a Mercedes G-Class use?
2 Answers
Mercedes G-Class, commonly referred to as the 'Big G', should use gasoline with an octane rating of 95 or higher. This information is usually indicated on the back of the fuel tank cap and in the vehicle's manual. Below are some relevant details: 1. Engine Specifications: The Mercedes G-Class is equipped with a 4.0-liter twin-turbocharged V8 engine, producing 421 horsepower and a maximum torque of 610 Nm. This engine reaches its maximum power at 5,250 rpm and its peak torque between 2,000 and 4,750 rpm. It features direct fuel injection technology and utilizes an aluminum alloy cylinder head and block. 2. Suspension System: The front suspension of the Mercedes G-Class employs a double-wishbone independent suspension, while the rear uses a solid axle non-independent suspension. Off-road vehicles like this typically use solid axle suspensions due to their simple structure, enhanced reliability, and durability. The use of a solid axle suspension also improves the vehicle's off-road performance.
I know that the G-Class generally requires high-octane gasoline, such as 95 or 98 unleaded. The engine of this car is quite powerful, and higher-octane fuel ensures smoother performance and reduces the risk of knocking. The owner's manual clearly states the recommended standards, and Mercedes-Benz officially advises following them. If you use lower-octane fuel, it may affect performance over time, increase fuel consumption, and lead to costly repairs. Always choose reputable gas stations when refueling—good fuel benefits the engine and makes maintenance much easier. Personally, I always opt for 98-octane when driving my G-Class, as it delivers quicker power response and provides peace of mind on long trips. Don’t forget to check the fuel quality label—don’t compromise on cheap, low-quality fuel to avoid potential breakdowns that could cost you more in the long run.
