many people say that 50:1 in a banshee is too little
many people say that 50:1 in a banshee is what you should do if it says so on the bottle
many people say that 40:1 in a banshee is the way to go
a lot more say that they run theirs at 32:1
yet many others say that 32:1 was good in the old days,when there were no 100% synthetics (like the amsoil interceptor)
so basically, this question will go on and on, and on...
i live on an island, where you can barely find 100% synthetic 2 stroke oil, so i have to use Yamalube, which is Semi-Synthetic...thus i run my banshee at 32:1
maybe if i get a 100% synthetic ill do 40:1.
However,my boat has a 25hp yamaha 2 stroke engine, i run the premix at 50:1
