On a serious note, the one that I use Star Tron Enzyme Fuel Treatment says it uses Kerosene. I use it really because it makes me feel better like I am doing something to help. Your favorite motors 496HO's 0W681083 and 0W681088 gen III cool fuel. I only fill up with 89 ethanol free. Only use 89 becasue I can get it without ethanol. Am I doing good / bad or no harm no foul?
