It will work in gasoline engines but the fuel has dye in it that will stain the hell out of it. The octane boost is great but not really needed for models.
As for putting it in a glow?? It won't run. The alcohol reacts with the platinum in the glow plug which starts the flame front propogation. AVgas will only put out the plug, also it burns very dry and it will remove all oil from your bearings and piston skirt which will ruin your piston and liner.
All it is is 100 octane gasoline with a tiny bit of lead (actually a lead substitute) I've got a John Deer mower with like 900 hrs on it all on avgas. My Pickup too. Basically only because it was there and I used to buy it in bulk of like 3000 gallons a week so it USED to be cheaper for me than auto gas. That's pretty much over. I see no advantage of running it in a gasser. It obviouselly won't run in a glow engine.
You can run it in gas engines. We ran 115 oct in our Giant Sacle racer. It ran well, but can cause early detonation and high engine temps. If you can set the timming correctly and cool the engine well enough, it's a good expensive alternative to regular gas. :roll:
All in all, there is really no good reason to use it, unless your riding in it!!
