I have always used the little small containers of 2 cycle oil to mix with 1 gallon of gas, however I have been hearing good things about Opti-2 2 cycle mix. Problem is the bottle of Opti-2 I have says it will mix 10 gallons of gas, but that only equals out to about .8 fluid oz. per gallon. This don't seem to be enough just by going by the amount I pour in from the small 1 gallon mix oil. How do you guys mix this oil mix for your equipment? Note I am only running a Husquvarna weed eater and blower with this mix. Any help will be grateful.
