A Stihl chain saw is a 2 cycle in which you have to mix the gas, I don't think the Honda is a 2 cycle is it. There are two types of 2 cycle oil, one for water cooled outboards and one for air cooled 2 cycle engines. Never use the one for the water cooled in an air cooled engine or you will burn it up.
