Get the all purpose stuff in the lawnmower area if you are uying you oil at Walmart or K-Mart.
yanno, I have a new bottle of TCW-3 outboard oil.. I don't really remember why I bought it ( couple years old ), havn't had a 2 stroke boat in years.. anyway, it's supertech brand and on the back of it, it says it can be used with lawnmower type air cooled engines which I know is totally bogus as not only do I know better, spec sheets off the internet say diffrently.. doesn't make sense to put a bogus label on the bottle when it could destroy the engine and that company 'could' have to pay for a replacement
