What are the effects of filling a Mercedes-Benz with 92 octane gasoline?
2 Answers
Mercedes-Benz vehicles generally have strong power performance, and using 92 octane gasoline may lead to insufficient combustion. Below is an introduction to related Mercedes-Benz content: 1. Mercedes-Benz SAM: The control unit, known as the Signal Acquisition and Actuation Module. If the SAM malfunctions, components such as headlights, turn signals, and wipers cannot be controlled while driving, posing safety hazards. 2. Mercedes-Benz: A German automobile brand, considered one of the most successful premium car brands in the world. It is renowned for its perfect technical level, stringent quality standards, innovative capabilities, and a series of classic coupe models. The Mercedes three-pointed star has become one of the most famous automobile and brand logos globally. Mercedes-Benz not only offers unparalleled quality but also a comprehensive range of models, currently producing mainly A-Class (compact cars), C-Class (mid-range sedans and coupes), E-Class (high-end sedans and coupes), S-Class (luxury sedans and coupes), and G-Class (SUV off-road vehicles).
I've been driving a Mercedes for a while, and sometimes when in a hurry, I filled up with 92-octane fuel, immediately noticing the difference. After starting the car, the engine noise had some irregularities, like small stones knocking, and acceleration felt sluggish during driving, making overtaking less smooth than before. This is mainly because Mercedes engines have a high compression ratio, designed to work optimally with 95 or 98-octane gasoline. The lower octane rating of 92 fuel leads to improper combustion speed, easily causing knocking. Knocking might sound like a minor issue, but long-term use can damage internal components like pistons and valves, accelerate carbon buildup, and increase fuel consumption. Later, when I took it to the repair shop for inspection, the mechanic said the spark plugs had turned black, and cleaning and repairs cost me several hundred. It's really not worth saving a bit on fuel costs—sticking to higher-octane fuel ensures stable, safe driving and peace of mind.
