I doubt very many people on here would know to tell you that aviation fuel is not the same as 110 vp or any other. 110 is 110. in this situaion, Aviation fuel on the other hand, at least the last time i bought it from GE, mind you was five six years ago, is around 101 102. but I was leaded babY . there is lead in it, at the same time with the intention of lubrication. The idea behind lead is as it passed through,is it was a micro liquid bead that passed through, sealed then passed through as a bead again. hinse acting a pre mix for two stokes that was intended on running in four stroke. most of this fuel has or had added oxegen added to it. the idea was to run at a given altitude. Now you cannot fly a little prop job above a certain altitude so you dont see it sold as much as it used to be. BUT if you know what you are doin for sure as far as tuning, it has the potential to create the same as a higher octane, and not have to tune it as much if you were traviling around the country trying to drag race a shee. pavement or asphalt would be the most benifitial to this......... if you dont understand how a multi dial jet works for people that they know,,,,,,, its the way of the future!!!!!! I cant wait to see someone use this idea on a matoon four case! sorry my spelling is bad.
