It all depends on how hot and humid it is where you are.
I'm still running in the only motor that is together at the moment, and 50 to 1 synthetic would be fine down south, but up here in summer a little more oil don't hurt.
I'm using Penrite MT 25T synthetic which I belive is designed to run 50 to 1.
If your oil is designed for 100 to 1 then fair enough.
I just got 5 litres of Valvoline 2 Stroke Racing oil for $20 on special, I'd probably run it 33 to 1in summer and 40 to 1 in winter (still mid to high 20 C here).
But each to there own.
