What is the difference between methanol gasoline and ethanol gasoline?
2 Answers
Methanol gasoline and ethanol gasoline differ in the following ways: Methanol gasoline is cheaper, methanol is an alcohol-based fuel with the lowest density and the least stable usage; Ethanol gasoline is regular gasoline blended with 10% modified ethanol, which costs more than regular gasoline. Methanol gasoline provides more power than ethanol gasoline, but ethanol gasoline has higher fuel consumption. Additional information: 1. Methanol gasoline: Methanol gasoline is a low-carbon energy source that can replace regular gasoline and is specifically designed for use in gasoline internal combustion engine vehicles. It is produced by blending industrial methanol or fuel methanol with denatured alcohol additives and existing national standard gasoline in a certain volume ratio. Methanol gasoline is cheaper, and methanol, as an alcohol-based fuel, has the lowest density and the least stable usage. 2. Ethanol gasoline: Ethanol gasoline is a new alternative energy source formed by mixing fuel ethanol processed from grains and various plant fibers with regular gasoline in a certain proportion. Ethanol gasoline is regular gasoline blended with 10% modified ethanol, which costs more than regular gasoline.
To be honest, I have quite some experience with these two fuels. Methanol gasoline is mainly synthesized from coal or natural gas. Compared to ethanol, it's highly corrosive—my old car's fuel lines rotted years ago, costing me a lot in repairs. Ethanol gasoline, made from fermented corn or sugarcane, feels more eco-friendly but has lower calorific value, resulting in slightly weaker power and possibly a few percent higher fuel consumption. Methanol also tends to cause more engine carbon buildup, which is annoying in the long run, while ethanol gasoline's high hygroscopicity can affect starting in rainy seasons or humid areas. Environmentally, ethanol is renewable and better for carbon reduction, whereas methanol, though clean, involves significant pollution during production. Overall, from a safety perspective, I'd recommend new cars prioritize ethanol gasoline and regularly check the fuel system.
