Hello!
Anyone have any experiences with 100 octane low lead Aviation gas?
Thanks!
Godspeed,

yes i have. I use it in just about everything. mowers, quad, Sled. IT works well, a little expensive and its a dryer fuel.

It works alright but because its a drier fuel some applications run into lubrication problems. I use it in my sled whenever I know it will be a long time between rides (like summer) because it is a very stable fuel.

Yes I have used it. But what are you using it in?

My starting intention was a 50-50 mix with 92 in a B/M Mod 2003 F5 and a 2004 Mod 440 for Hill Cross and see if I can realize any significant difference.....i.e...Easier tune, cleaner burn & more power. I want all the horses I can corral in them small blocks.

depending on what is done to the motors you can actually see a loss in power even with a 50 50 blend you would want to advance the timing I would think. More octane does not mean more power it just means you can run more compression or timing ect without it detonating, Watch your jetting then jet down and play with timing while watching ets in a controled test, I would think unless your running alot of compression you would want to start with about 20% 100LL to 80% pump gas and bump your timing a few degrees at a time, and if that doesent help lean it out to get some heat back in the pipe.
