Re: Bright green gas

Eureka moment. Fresh off the presses. Nearly 8 months later:
I was going up the stairs in the garage and passed by the samples. A lot has changed. We got bright green, but not where I thought it would be. See pix.
It's the ethanol gas with copper tube in it. Somethings happened because the copper is fused together and stuck to the jar.
Looks like water actually inhibits green.
Probably changed the order since I moved to photo.
From the right side to left;
1. free" control - nothing in it.
2. "free" with copper.
3. Ethanol control - nothing in it
4. ethanol with copper - bright green
5. same as 4 except has the water in it.
6. Ethanol with a brass fitting in it.
The "free" non-ethanol samples are much lighter and less evaporation. I'd have to recommend using that over ethanol gas if you're going to store with gas in it for more than a few months.
ps: Suggests a lot of subsequent experimentation, but I think I'll conclude this for now and maybe document. The Cad guys are worried sick about it gelling, but I don't see that happening. It takes years to "tar" up a gas tank. Mine sat over 5 years in a field before it went solid. Have no idea what gas was in it but probably had many contaminates.
