What is e92 fuel?
2 Answers
92-octane gasoline is regular unleaded gasoline that does not contain alcohol. E92 gasoline is based on 92-octane gasoline with the addition of a certain proportion of ethanol and additives. Understanding gasoline grades: Gasoline grades are marked according to the octane rating. The higher the gasoline grade, the higher the proportion of isooctane. For example, 93-octane gasoline has a higher proportion of isooctane than 92-octane gasoline. The choice of gasoline grade mainly depends on the engine compression ratio. The higher the compression ratio, the higher the fuel grade should be. E92 contains only 10% alcohol. If you usually use 92-octane gasoline, mixing it with e92 will only result in reduced power and shorter driving range. If you usually use e92, mixing it with 92-octane gasoline may improve power and increase driving range. Precautions for refueling: Cars should not change fuel grades arbitrarily. If a lower grade fuel is used, it may cause premature combustion, leading to engine knocking. Incomplete combustion of gasoline will also increase carbon deposits, which can clog pipes and nozzles, resulting in reduced vehicle power and increased fuel consumption.
I just drove an E92 BMW, that 2007 3 Series coupe with the chassis code E92, and it definitely doesn't run on just any fuel. My car requires high-quality unleaded gasoline, recommending fuel with an octane rating of 92 or above, otherwise the engine is prone to knocking, affecting acceleration performance. Engine oil is also crucial—I regularly change to full synthetic oil, like the BMW-specific 5W-30 viscosity, to ensure smooth lubrication and extend engine life. During routine maintenance, fuel choice is key, as low-quality oil accelerates carbon buildup. If you're confused about fuel types, check the manual or consult an expert immediately.
