I filled up at the above fuel station this week. While the fuel was dispensing, I was reading the crap on the pump. In my area, Citgo diesel can be anywhere from 5-20%bio!!! :wow :wow :wow How in the heck are we supposed to formulate our 2 stroke under variations like that?????? Because they don't tell you the "ACTUAL" %.........they don't have to!!!! Either way, I'm still getting good mileage.........and that's using 1/2oz 2 stroke per 1 gallon of fuel......... or about 16oz per fill up!!!

Well hell that like the gasoline pump out here it could be up to 10% ethanol... (Up to... Meaning it might contain it it might not...)I would still hold to it who know if Bio is actually in it and how much...
