Not quite sure on the # of gallons but I've ran 20% all year. I bought the engine on 10/22/05 and for some reason it is still tight. I spent a little over gallon on the break in process and after every run, I make sure that the piston sets near bottom dead center. I think I have at least 8-10 gallons through it.
