Does anyone have a "proven" formula (octane booster) for when you need 93 and all the marina only has is 89 octane? I was face with that this weekend.....I put enough 89 in to make it back to my home marina at slow speed.

If I have to fill up on the lake I put in 3 bottles of 104+ octane boost and have not had any problems. I have my timing locked at 35 degrees.

Here ya go.
