using Star Tron
 

I started using star tron in my small gas engines and decided to use it in my glow engines.

Its cleaning the fuel tanks out along with the engines, they seem to run better after a couple or three tanks of the stuff. I had one tank that had been in an old plane for 30 years, I took it out and it had green slime in the bottom. I put some of my glow fuel with star tron in it and the next day it looked new again.

Its good for two or four cycle and does not attack plastic or rubber.
