92 ethanol gasoline and 92 gasoline mainly have the following differences: Different raw materials: 92 ethanol gasoline is a fuel processed from grains and various plant fibers, forming a new alternative energy source by mixing ethanol and regular gasoline in a certain proportion. The isooctane ratio in 92 gasoline accounts for about 92%, so the higher the octane number, the better the gasoline's anti-knock performance. Different lead content: The commonly referred to gasoline is unleaded gasoline (containing trace amounts of lead), while ethanol gasoline refers to adding a certain proportion of fuel ethanol (commonly known as alcohol) to ordinary unleaded gasoline.

I've been driving for fifteen years and have used both types of 92-octane fuel. The most obvious difference is that ethanol-blended gasoline contains 10% alcohol, while regular gasoline is pure. The alcohol blend makes the exhaust cleaner, but it slightly reduces power, especially noticeable when climbing hills with the AC on. The key point is that fuel consumption increases—I've tested it and found it burns an extra half-liter per 100 kilometers. Older cars need special attention, as alcohol can corrode rubber fuel lines. My 2008 car had to have its fuel line seals replaced. However, newer cars are generally compatible with ethanol-blended fuel, and you can safely use it if the fuel filler has an E10 label.

As a mom who drives my kids to and from school every day, I always do the math before refueling. Ethanol-blended gasoline is a few cents cheaper per liter, which seems like a good deal at first glance. But in reality, I've noticed a shorter driving range—my car used to go 550 km on a full tank, but now it's only about 510 km. A mechanic explained to me that this is because alcohol has a lower heat value than gasoline, essentially like diluting the fuel with water. Plus, water tends to accumulate in the fuel tank, especially if you frequently drive short distances. Eventually, I switched back to regular 92-octane gasoline. Although it's a bit more expensive per liter, it turns out to be more cost-effective and hassle-free overall.

With ten years of experience in auto repair, I've disassembled countless fuel systems. The biggest issue with ethanol gasoline is its corrosiveness: rubber oil seals tend to swell and deform, while metal parts are prone to rust. The most extreme case I've seen was an old Mercedes with its fuel injectors completely clogged by alcohol residue. I recommend avoiding long-term use of ethanol gasoline for cars manufactured before 2008. New car owners should also be cautious: don't mix two types of fuel, as it may cause separation. If you must switch fuel types, it's best to wait until the tank is nearly empty before refueling to minimize the mixing ratio. It's advisable to add a bottle of fuel system cleaner every 5,000 kilometers to remove gum deposits.
