Staubil oil?? Does it say it mixes with alcohol? Not all two stroke oils mix with alcohol. I use Klots blended oil, it's a synthitc blend with 20% Castor. Only time I ever add oil is if it is under 17% oil in the blend. Why do you need it?Store bought fuel usually does not require added oil. When I was using Wild Cat 16% oil I did add two ounces of the Klotz. I like my oil to be at 18% blended oil.
