To mix the fuel,use a one gallon gas can .Use it specifically for your premixed gas .At wal-mart ,you can buy 2 cycle oil in the auto section that has a seperate compartment at the top with different premix ratios labeled on it .All you do is squeeze the bottle and the oil will travel up to the seperate compartment.It's really easy,no skill needed.The ratio for the 780r is 32:1 It's labeled on the compartment on the oil you buy.Just squeeze enough oil till it reached the 32:1 line and pour that into 1 gallon of gas .Mix it around a bit,then you have a gallon of premixed 32:1 gas .
Just make sure and label the gas can somehow so you dont put premixed gas in your lawn mower!
