I have a 1960s US military stove. It calls for white gas. I am curious, what was white gas in that era? Is it the same as ethanol free 93 octane now? I read a website that said white gas is additive free unleaded gasoline. Is ethanol free fuel in the US additive free? I know that Coleman fuel is commonly referred to as white gas. Is this actually the 1960's version of white gas?
