I use to only use Byron 10% but can't really get it here anymore in the Chicagoland area so I switched to Wildcat Premium Extra 10%. I liked the Byrons, was very high quality. I think they have a high level of quality. Course I like to add extra castor and few drops of Armour All, but thats just something left over from my controline days. It's good fuel. Good flying to you.
