YIKES!!!!! Also, if you must make your own substitute, can mix one gallon of gas with 1/2 gal of 30-wt. oil. It also appears in many original owner's manuals. Roomie, who grew up with the "ugly boxy practical cars" overseas, decided she had to love my "taxi" when doing hurricane evacuation preparation a few years ago. When she found out the alternatives for fuel (including a couple gals of Wesson Oil) in a pinch to get out of Florida/path of a hurricane, she became very impressed.

Also, for good upper cylinder lubrication, use Lucas or 2-stroke outboard motor oil (same thing as lucas sans the injector cleaner).
