What is the Difference Between 92 Octane Gasoline and 92 Octane Ethanol Gasoline?
2 Answers
Here are the differences between 92 octane ethanol gasoline and 92 octane gasoline: 1. The isooctane ratio in 92 octane gasoline accounts for about 92%. The higher the octane number, the better the gasoline's anti-knock performance. 2. 92 octane ethanol gasoline is a new alternative energy source formed by mixing fuel ethanol processed from grains and various plant fibers with ordinary gasoline in a certain proportion. Ethanol gasoline is produced by adding a certain proportion of fuel ethanol to regular unleaded gasoline, which has good cleaning effects. 3. 92 octane ethanol gasoline is cheaper, but this type of gasoline also burns faster. 4. Ethanol has a certain unclogging and cleaning effect on impurities in the car's fuel tank or fuel lines. 5. When refueling, car owners should use the fuel grade specified by the vehicle.
Although 92-octane gasoline and 92-octane ethanol gasoline share the same octane rating, there are noticeable differences in actual usage. Regular 92 gasoline is purely refined from petroleum, while ethanol gasoline contains about 10% bioethanol. The most obvious difference is fuel consumption – a full tank of ethanol gasoline will typically provide 30-40 kilometers less range due to ethanol's lower heat value. There's also a slight reduction in power, with less crisp engine response during rapid acceleration. However, ethanol gasoline has its advantages: it's more environmentally friendly with cleaner exhaust emissions and slightly cheaper. One important note is that older vehicle models may have rubber fuel lines susceptible to ethanol corrosion, so it's advisable to check the manual before refueling. Additionally, cold starts can be more challenging in low temperatures, especially during northern winters, so pay attention to these details to avoid morning no-start situations.
