If only I could find that earlier thread... Was numerous pages with all sides represented and no point of view was forcefully discounted
Wish I knew more about this stuff...
I don't participate on those discussions any more, have found that most people are set on their way and not willing to even consider trying anything different and OPTI-2 is different, and to a point I understand, jumping from 30 years+ of using 32:1 to using 100:1 will look at first glance that you will be destroying the engine in no time and only an idiot will destroy an engine knowingly so, but, technology keeps advancing and we shouldn't dismiss it from the get go just because we are not familiar with it, heck if my uncle were alive he would have slapped me unconscious if he saw me using less than 8:1 in a 2 cycle because in his day that was already lean on oil, I grew up around 32:1, then went to 50:1 later, and contrary to common sense it is the oil manufacturer that knows best the ideal ratio for their oil, some oils must not be mixed higher than 32:1 or will foul the engine some you can go as fat as 8:1 and it is OK by them but not higher than 50:1, others like Amsoil Saber Pro doesn't like more than 50:1 and as high as 100:1 and here is were OPTI-2 goes weird, it is 100:1 for everything, I have tried 80:1 without any fouling but the engines get heavy, slow to rev, they sound un-happy, IDK how to explain it then I go back to 100:1 and once they burn the excess in the crankcase they come alive again. Another thing will be if I were using a highly strung engine, kart engine for example, then I'll use 12:1 or more oil and it will probably will be de-gummed castor oil since the engine will wear out long before clogging anything.
