Didn't you mean caustic?
Yes in chemistry there are many oxygen adders...the trick is cost availability, cost, easily mixed with alcohols and mineral, plant, or synthetic lubricants, and COST
FOR many modelers they are oblivious to health hazards of some of the exotic oxidisers/reagents available
IF there is any more available, or lower cost oxidiser---- the model fuel industry would most assuredly be blending with it
Maybe some member with a chemistry or fuel engineering degree can enlighten me and you....
.I have previously read many recipes for exotic fuel blends....always seemed to get back to Methanol, Nitromethane, and pure castor, or pure synthetic, or various ratios of each lubricant.
BTW most additives like propoleine are not sold by hobby shops any more but a crafty google can find many technical chemicals sold to university for research....I even have a link to small qtys of radioactive materials for sale

Also...I have no clue what you engine is but many many engines can be deliberately built for or adapted to FAI fuels...no Nitro..various ratios of Methanol and lubricants...international competition FAI is generaly 80/20 blends

I have glow engines ranging in size from a .28 up to a 1.08. What mods would I have to do in order to run FAI fuel? The price of glow is getting a little silly. I remember when it was $5.00/gallon and that was 10% nitro.

Generally you just need a good hot long reach plug and adjust the needles a little bit. If you have idling trouble, add 1-2% acetone to a jug of FAI fuel. My European engines ran superbly on it albeit at a 400-800rpm loss over using 5-10% nitro. The magic CR for FAI fuel is around 13.5:1, but even without a head shim, you’ll probably still be under that number. The engine won’t care. It’ll run good provided it’s in good mechanical order.
