Whats a good Mixture ratio???? im using the bottle they give me and I usually fill it up to the 25-30-1 line and to the bottle of the neck of the white bottle with 2 stroke motor. IS this accurate???

Depending on the oil I use I pre-mix at 40:1 or 50:1. Our gas jug in the shop currently has premium unleaded, 91 octane, mixed 50:1 with Bel Ray MC-1.

Yup, thats good.

I use 40:1 for everyday and 50:1 for race day.
