Premix question

[Coochas]

I am going to pre-mix starting next season as there is doubt about the health of my OMP. Darryl Drummond recommends 1 oz racing 2-stroke oil/gallon gas.

Do most of you just add the necessary amount of oil to the fuel tank before/after filling with gas or do you truly need to premix the oil with the gas before pouring it into the fuel tank?
Thanks

Mix it before you put it in the car

We add 6 OZ per 5 gallons. As SOP we always add the 6 OZ to the fuel jug before filling it.
