For most Eska 7.5 HP 2-stroke outboards, the standard fuel mix is 40:1 ratio. That’s 3.2 ounces of 2-stroke oil per gallon of gasoline.
But if it’s an older model from the '60s or early '70s, some manuals called for 24:1 (5.3 oz/gal). However, most folks today run modern TC-W3 marine oil at 40:1 safely, since newer oils are way better than what they had back then.
