I have a 46 J-3C65 - and I use auto gas - 87 octane and add 4oz mystery oil per 5 gal of gas - -- 87 octane has .50 ml of lead per gallon which isn't enough and 100 LL has 2.0 ml of lead per gallon which is too much - does anyone know the ideal lead content of what the fuel should be for the J-3C-65 ???
