Mixing E92 and 92 gasoline won't have a significant impact. E92 simply contains 10% alcohol. If you usually use 92 gasoline, mixing in E92 might only result in a slight decrease in power and a shorter driving range per tank. Conversely, if you typically use E92, mixing in 92 gasoline might make the car feel more powerful and increase the driving range per tank. Ethanol gasoline for cars, as a clean engine fuel, offers the following advantages: 1. High octane number and excellent anti-knock properties. 2. Ethanol has a high oxygen content of 34.7%. Adding 10% ethanol to gasoline increases the oxygen content to 3.5%. 3. Using ethanol gasoline can effectively reduce vehicle emissions and improve the energy structure. Domestic studies show that E15 ethanol gasoline (with 15% ethanol content) reduces hydrocarbon emissions by 16.2% and carbon monoxide emissions by 30% compared to pure unleaded gasoline. 4. The production of fuel ethanol is resource-rich and technologically mature. When blending less than 10% ethanol into gasoline, no major modifications are needed for existing car engines, allowing direct use of ethanol gasoline.

After years of driving, I once experimented with mixing 92-octane gasoline and high-ethanol fuels like E85 – that was a mistake. After blending, the engine suffered from unstable idling and weak acceleration, and I ended up spending money to repair the fuel system. 92 is regular gasoline, while E92 likely refers to high-ethanol blends like E85. Mixing them causes a sudden change in ethanol concentration, which can corrode metal components, absorb moisture leading to fuel freezing, and even damage fuel injectors. Most vehicles aren’t designed for high-ethanol fuels, increasing the risk of engine knocking or stalling. I recommend sticking to the manufacturer’s recommended fuel grade, such as pure 92 or small amounts of E10 blends. Don’t take risks to save money – safe driving comes first. Now I understand that cars are like friends: they need the right fuel to stay reliable long-term, and professional repairs are the smarter choice when issues arise.

From a cost-saving perspective, blending 92 and e92 sounds appealing, assuming e92 is a cheap fuel like E85. However, in practice, the mixture reduces heat value, increases fuel consumption, and decreases mileage, ultimately costing more. If the vehicle isn't designed for flexible fuel, it may cause engine shaking, power loss, and corrosion of rubber seals, leading to expensive repairs. Using pure 92 is much more stable, occasionally adding proper additives without mixing different types. Saving money shouldn't compromise the car's health. In the long run, regular maintenance is more economical. Consult gas station staff or the manual if in doubt, ensuring you don't lose more than you gain.

Regarding mixing 92 and E92, the key lies in fuel compatibility. 92 octane is standard, while E92 like E85 has high ethanol content, with significant differences in combustion temperatures. Mixing them can easily cause knocking or incomplete combustion, reducing performance. Ethanol's strong water-absorbing properties can accumulate moisture, corroding the system and harming long-term reliability. Standard vehicles can only handle low-ethanol fuels like E10, while flex-fuel vehicles are designed for E85. I recommend avoiding regular mixing and opting for a single fuel type to ensure engine efficiency and smooth driving.
