Mix it as directed on the container and you'll be fine. I really like the Opti-2 that comes with the pre-mix option. There is a small vessel on the side with calibrated marks for one or two gallons of gas that you fill with oil and mix that amount with one gallon of gasoline. Perfect mix every time. Opti-2 is thick and so much sticks to the sides that I usually add about 1/8" over the measured mark or prop the container up and let it drain completely into your fuel container. Maybe I'm being anal about my mix but at least I know I'm getting what the manufactuer says to use.
