With all the talk about mixing oil and gas, and the recurring delima of Mobil 2-stroke oil, did I add oil or not, does anyone know if adding a little food coloring to the mixed gas will harm your engine?? A guy could have designer colors even.. Just think of the possibilities.
I use a dye at work that would do the trick but I wouldn't add it to my fuel. It's a powder that disolves. IMO, kind of like adding sugar in your gas tank.
