The U.S. is 16 fluid ounces for a 6-gallon fuel container. (One pint equals 16 ozs. or 2 cups) In the U.K. it would be 20 fluid ounces.

I run em 2 oz per gallon on 100:1 Amsoil pre mix. Make sure you NEVER use ethanol "infected" fuel. I have never had a failure with Amsoil 2 stroke oil in my outboards or saws. Have 200 of them. And I DO run 'em constantly.
