Why dye your fuel?
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.
