I just buy the packets that are premeasured for 70:1 (1.8oz packet for 1 gal of gas) my ratio is not exact, I just put 2 packets =3.6oz Opti 2 in my gas jug and then put 2 1/2 gals in it. not sure what this figures out too exactly I'm just guessing at close to 80:1.

Mix it at 100 to 1 just like Interlube recommends.
I have ridden 2 of Baird's 100 to 1 66 cc two stroke bikes and they are
some of the fastest and cleanest bike ever. Lots of miles on them too.
GPSed one at 54 mph with a 28 tooth rear sprocket!
Opti 2 really works and the next 2 stroke I build is getting 100 to 1 Opti
from mile one. It will be broken in using their recommended technique.
It was going to be my secret weapon with the 4 strokes too but seeing
that Opti-4 is sponsoring the race at Willow Springs the secret is no more!
