I went ahead and bought the walmart super tech oil to mix in my outboards but i got a question. On the bottle of my evinrude it says 50:1 is 3 oz to 1 gallon. On the super tech oil it says 2.6oz to 1 gallon? Do i mix it to 2.6 or to 3oz? I bought a measuring jug down there also that has different oil ratios and gallons of gas but on it, it measure little less than 16 oz oil for 6 gallons of gas. How do you guys measure out your oil? should i just mix it 3oz to 1 gallon? i have been using that jug to measure my oil out i just fill it up to however high it says for what gallon of gas at 50:1. not exactly 16oz to 6 gallons of gas but its close(little less). should i just mix a little more from now on to be safe?
