If anyone is ever in Chico, Ca be sure to stop in their HobbyTown USA there. They have some local guys making fuel & they sell it at that store. When I saw the prices From $9 fo 10% to $12 for 15% I had to ask the guy at the shop if this stuff was any good. He told yes it's great fuel, it's the only fuel the local club there uses. So I bought a couple gallons of 15% for $12 a piece and it was excellent fuel!
