What do you come up with?

I don t know how step tracks his fuel. My 150 merc 2 stroke got 2 mpg, so I would use my trip on gps and when I went 40 to 60 miles, I knew I needed 20 or 30 gallons and would add oil per fuel consumption

50 to one is wide open consumption so you don t have to get it exact

I put in a gallon (128) ozs plus 24 ozs. (152) ozs for 56 gallons and it seemed good. Smoke coming from exhaust. Not to much just enought I think .
