RE: Four Stroke vs Two Stroke Fuel Differences
I use Omega 15% Synthetic/castor blend . I have Saito and Magnum 4 strokes and OS, Supertigre and Evo 2 strokes and all run fine on it.
I think full synthetic is O.K but Magnum recommends a castor blend with thiers. So I can cover all bases with the Omega.
