Now that fuel for glow engines has gone ballistic, I am tinkering with mixing my own fuel. I have a couple gallons of methanol which is absolutely clear. If I mix castor oil with it, it will still be almost clear. I don't know what color nitro is because I have not found any yet, but I do not want clear colored fuel. So my question is: can I put a little food coloring in the fuel? If n not, what can I color it with so that it will be readily visible in the lines?

Why not simply use a small amount of synthetic oil (AeroSave or Klotz, for instance)?

The nitro I have is coloured. I've had it for years, intending to mix my own fuel, but so far I've been too lazy to actually mix any. To my recollection, it's yellowish. If it changes colour, it has become chemically unstable and should not be used; at least, that's what it says on the 1-litre bottles I have.

A couple drops of green loctite will work...... Seriously, I don't know what type of colorant is used in glow fuel but since you are mixing it yourself you really don't need to color code it, you know what the mix ratio is.

Color coding it was never the object. I simply wanted to color it so it would be readily visible in the fuel lines in order to see if there was a solid stream of fuel being delivered to the engine or if there were bubbles in it. If that were possible without coloring it, I would not worry about coloring it.

Info on fuel colorant/dye

I would contact Wildcat or any other glow fuel provider. You could also talk to your local fuel distributor, they should have dye on hand for off road diesel.

Nitromethane is available from Torco on Amazon and eBay...

Are you sure you won't be able to see the bubbles even if the fuel is colourless?

I know I could.

perreback, I don't know if I could see the bubbles if the fuel were colorless. If I could, then there is no problem. Maybe I should just draw some methanol through a line and see how visible it is.

The problem with artificial coloring is that eventually it will stain the inside of your tank and fuel lines, making the initial intent useless. Instead of castor oil, use synthetic oils that already are colorful. I believe this option was posted above already.

I would imagine that the methanol will be pretty much invisible in the absence of bubbles, but I'm fairly sure you will see the bubbles if there are any. Think soda pop (e.g. Sprite) in a glass --- bubbles clearly visible. The same, I should think, will be true of bubbles in a fuel line.
