Some like 50:1 IMO I like 40:1 or 3 1/2 oz of 2 cycle oil to a gallon of super unleaded motor gasoline..

128/desired mix ratio = ounces per gal

Performance outboard = 128/40 = 3.2 ounces per gal.

2.6 is 50:1 and most of us just run 3.0 ounces per gal and call it good, (43:1). On a drag motor with short hard hard bursts of accelleration you probably want to be closer to 35:1.

Jay Smith, Eagle One, Chris Carson etc, can give you those numbers more accurately if you need.
