What is the Difference Between 92 Octane Gasoline and 92 Octane Ethanol Gasoline?
4 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.
From an environmental perspective, 92# ethanol gasoline does have advantages over regular 92# gasoline. It contains about 10% plant-based ethanol, which significantly reduces carbon dioxide and particulate emissions after combustion. However, fuel consumption increases by approximately 5%-10%, effectively raising vehicle operating costs. For engines, ethanol gasoline offers better cleaning properties that can automatically remove carbon deposits in fuel systems, but its strong moisture absorption tendency may lead to water accumulation and tank rust. Many northern regions now mandate ethanol gasoline use, while southern gas stations still offer both options. Special note: motorcycles using ethanol gasoline require pre-warming to avoid fuel cutoff issues - a particularly common problem with scooters.
After getting used to regular 92-octane gasoline, I'm really not accustomed to ethanol-blended fuel for the first time. The most noticeable difference is the dull power response when stepping on the accelerator, especially when climbing hills with AC on - you can clearly feel the engine struggling. The gas station attendant said it's because ethanol burns at a different rate. Also, you need to clean the fuel tank more frequently since ethanol absorbs moisture; leaving the car unused for six months might result in water accumulation at the bottom. However, it affects new cars less as modern engines have auto-correction functions - the ECU automatically adjusts ignition timing when detecting ethanol. Calculating practically, though it's 0.3 yuan cheaper per liter, you'll burn one more liter per 100km, making it less cost-effective for long trips. Our fleet's real-world tests show that using pure 92-octane gives better highway range and is more economical.
