I was wondering if anyone has used alcohol in their two stroke engines, if so did you just mix the oil in like you would gas please let me know, at over 50 cents a gallon price difference I would like to know if it could be done.
I doubt it would work. In a 2-stroke, the oil and gas mix is both the lubricant and the fuel. It might be difficult to get the right combination of lubricity and octane. The oil would probably need to be custom made.
2 stroke with Alcohol can be done. All r/c cars and planes use this. There are many problems with it. Alcohol will attract water like a magnet causing water in your fuel to be a problem and cause corrosion of steel parts, inside tank etc. It will also tend to eat some plastics. The biggest problem is rejetting the carb. Fuel and alcohol have different densities so they behave differently. You would have to increase your jet to allow more alcohol so it won't lean your motor out and cause a seizure. So yes it can be done but sounds like more hassle than it is worth.
