Is China 6 fuel ethanol gasoline?

[OColin]

China 6 gasoline is ethanol fuel. Here is relevant information about ethanol gasoline: 1. Pure gasoline vs ethanol gasoline: The so-called pure gasoline here actually refers to 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, with this proportion being 10%. At gas stations, gasoline grades followed by the letter E indicate ethanol gasoline. 2. From an environmental perspective: Ethanol gasoline is undoubtedly better because the ethanol in it is a renewable resource, and as an automotive energy source, its emissions are cleaner; however, pure gasoline has limited resources and causes greater pollution to the atmosphere, making it less suitable as a strategic energy source in the long run. 3. From the perspective of vehicle driving performance: Pure gasoline is obviously better, as ethanol has a high heat of vaporization, and its evaporation temperature under theoretical air-fuel ratio is higher than that of conventional gasoline. This affects the formation of the mixture and combustion speed, leading to a decrease in vehicle power, fuel economy, and cold start performance, which is detrimental to vehicle acceleration. These are also the reasons why many car owners are not very fond of ethanol gasoline.

I've studied the China VI standard fuel, which doesn't refer specifically to ethanol gasoline but rather the fuel requirements under China's sixth-stage emission control standards. Ethanol gasoline is actually a type of fuel blended with ethanol, such as the common E10 containing 10% ethanol, aimed at reducing carbon emissions and pollution. China VI-compliant fuels can be either regular gasoline or ethanol gasoline, as long as they meet the targets for reducing pollutants like PM2.5 and nitrogen oxides. Many cities promote ethanol gasoline to meet the China VI standards, but the two are not equivalent. I recommend checking the labels at gas stations and choosing genuine China VI fuel to ensure your car remains eco-friendly and hassle-free, while also adapting to future stricter emission regulations.

As a veteran driver with twenty years of experience, I don't think all China VI fuel is ethanol-based. Ethanol gasoline is blended with alcohol, which I often use in Northeast China. It's a bit harder to start in cold winters, but it produces fewer emissions; regular gasoline offers more stable power. The China VI standard requires cleaner fuel, but it doesn't necessarily have to be ethanol-based. Nowadays, most gas stations sell China VI standard fuel, including both ethanol and regular types, at similar prices. From my experience, ethanol gasoline tends to have higher fuel consumption on long trips, but the exhaust is cleaner. I recommend beginners start with regular China VI fuel to get used to it first.

From an environmental perspective, the goal of China VI gasoline is to reduce air pollution, but it is not mandatory to blend ethanol. Ethanol gasoline, which uses biofuels, can indeed reduce carbon emissions and is lower in carbon than pure gasoline, but it has its pros and cons, such as being prone to corroding rubber components. The China VI standard supports various fuel types, including non-ethanol variants. By choosing China VI-certified fuels, we can contribute to blue skies and white clouds while avoiding misunderstandings.

From an economic perspective, China VI fuel is not entirely ethanol gasoline. Ethanol-blended fuel may sometimes be cheaper but slightly increases fuel consumption, resulting in minimal difference in overall expenses. China VI is merely an emission standard that can apply to both regular and ethanol-blended fuels. I've done the math—using China VI fuel saves more on fuel costs compared to older standards and extends engine life. For family car owners, I recommend choosing reputable brands of China VI fuel to balance environmental concerns and budget, without overspending for the ethanol label.
