Can 92 Ethanol Gasoline and 92 Gasoline Be Mixed?

92 ethanol gasoline and 92 gasoline can be mixed. Here are the detailed explanations: 92 Ethanol Gasoline: 92 ethanol gasoline does not affect the driving performance of the car and also reduces the emission of harmful gases. As a new type of clean fuel, ethanol gasoline is currently the focus of renewable energy development in the world, in line with the national energy substitution strategy and the development direction of renewable energy. It is technically mature, safe, and reliable, fully applicable in the country, and has good economic and social benefits. Ethanol gasoline is a mixture rather than a new compound. Adding an appropriate amount of ethanol to gasoline as a vehicle fuel can save petroleum resources, reduce air pollution from vehicle exhaust, and also promote agricultural production. 92 Gasoline: 92 gasoline is gasoline with an octane number of 92, suitable for mid-range cars. Considering the current situation of the production, storage, transportation, and use of automotive gasoline products, as well as the demand for technological transformation of oil product manufacturers and vehicle emission control technology, the main indicators are equivalent to the current European standard levels, meeting the requirements of the domestic fifth-stage gasoline vehicle pollutant emission standards. It helps reduce vehicle pollutant emissions, which is of great significance for protecting the environment and improving air quality.

I've been driving for over a decade and encountered this issue many times. Mixing 92-octane ethanol gasoline with 92-octane regular gasoline is fine. Once when my fuel tank was nearly empty on the highway, the service area only had ethanol gasoline, so I mixed a whole tank. The driving performance felt the same as regular fuel, and there was no change in fuel consumption. However, I should remind you that ethanol gasoline can dissolve impurities in the fuel tank, and mixing might clog the filter. After driving about 3,000 kilometers that time, I replaced the filter. If your car is over ten years old, it's better not to mix fuels long-term because the fuel system seals in older cars are more susceptible to ethanol corrosion. In short, mixing in an emergency is okay, but for long-term use, it's best to stick with one type of fuel.

I usually pay great attention to vehicle maintenance and have researched extensively. Although mixing 92-octane fuels won't immediately damage the car, it carries many hidden risks. Ethanol gasoline has high water content, and mixing fuels can increase moisture in the fuel tank, leading to rust and corrosion in fuel lines over time. This is especially problematic for those who frequently drive short distances, as the water doesn't have a chance to evaporate. Additionally, ethanol's strong cleaning properties can dislodge old deposits and flush them into the fuel system. My neighbor experienced clogged fuel injectors after mixing fuels, costing hundreds in repairs. If you must mix fuels, it's advisable to clean the fuel system and tank during your next maintenance. My principle is to visit a few more gas stations rather than mix fuel types.

This issue isn't that complicated. As the manual states, E10 gasoline (92 octane) is essentially still gasoline, just blended with 10% ethanol, so mixing it with regular gasoline won't affect combustion at all. Once when I returned from a business trip with only half a tank of ethanol-blended fuel left, I directly topped up with regular gasoline and drove without any abnormal engine noises or vibrations. Remember, matching the octane rating is key – mixing 95 with 92 octane might actually harm your vehicle. However, ethanol-blended gasoline has a shorter shelf life, so avoid letting the mixed fuel sit unused for too long to prevent water sedimentation from potentially affecting startup. My advice: burn through this mixed tank promptly and refill with pure gasoline afterward to avoid complications.
