You maybe right...
But it also says in the manual to always use the recommended ratio and that was written as 32:1.
Even Lawnboy ashless says 32:1
So do you still go with Brison's recommendation or the recommendation on the oil bottle ?
BTW: Wouldn't I see a lot of white smoke if there is too much oil in the fuel ?

37:1 mix? I am reading my manual and it says to go 64:1 for petroleum based and 80/100:1 for synthetic. That seems like way more oil than is necessary and they even say that it could damage the engine voiding the warranty. FWIW I am running Klotz in my new Brison 3.2 at 80:1. It runs great. I know this doesn't have anything to do with your question, but I do know that my Ryobi weed wacker runs terrible if I get too much oil in the fuel. I haven't run my Brison with too much oil so I don't know if it would have the same effect. That might be something to look at.
