New homebrewer here - Just ran my first gallon of 0% through my Moki today.
Engine is on a profile plane, with an externally mounted tank. (Low fly-bys to check fuel level in flight)
Problem is this mix is completely clear. I need to dye this concoction like commercial fuel.

What is a good over-the-counter source of alcohol-soluble dye which won't hone/goop up my motor?

Why dye your fuel? I recall using clear fuel with undyed synthetic oil with no problems. If you add castor it will be slightly gold in color.

he wants to see the fuel level in flight...read his post!

i use klotz benol, nice red color but it's castor.

for epoxy/polyester work i use a VERY strong dye in various colors. one tiny drop would be enough to turn a whole gallon bright red, orange, green....i can't imagine such a small amount having any adverse affect on the engine but i also don't know if it's compatible with meth.

I use good ol' liquid food coloring. It only takes about six (6) drops per gallon. I call my fuel "blue goo".

Mr Ed

MartyG, I am wanting to brew my own 0% fuel and I was wondering what your recipe was. Could you tell me?
