What type of gasoline should the C200 use?
2 Answers
The Mercedes-Benz C200 should use 95-octane gasoline. The reasons are as follows: 1. The primary criterion for selecting gasoline octane rating is the engine's compression ratio, which is also a core energy-saving indicator in modern vehicles. Engine operation consists of a cyclical process of "intake-compression-combustion-exhaust-intake" in the cylinders. The compression ratio is the ratio of the cylinder volume when the piston is at its farthest and closest points in the stroke. 2. The best way to reduce fuel consumption costs is to increase the engine's compression ratio. Increasing the compression ratio only changes the piston stroke—the more the air-fuel mixture is compressed, the greater the combustion reaction, leading to more complete combustion. However, a higher compression ratio requires gasoline with higher anti-knock properties, meaning a higher octane rating. The Mercedes-Benz C200 has a high engine compression ratio, so it must use 95-octane gasoline to avoid damaging the engine.
As a Mercedes-Benz C200 owner, I always insist on using 95-octane gasoline. Its engine has a relatively high compression ratio, and while 92-octane can be used, it may lead to knocking and carbon deposits over time, affecting engine longevity. I pay attention to the quality of gas stations, choosing well-known brands to avoid issues caused by inferior fuel. Higher-octane fuel not only improves throttle response but also ensures more stable fuel consumption and a smoother driving experience. I recommend new owners develop the habit of checking the fuel cap advice and avoid opting for lower-octane fuel to save money. Using additives during regular maintenance can also help prolong engine health. These small details contribute significantly to the car's overall performance and safety.
