Does meth go bad?
Crashly, I didn't call you a dumbass, or put you down at all. I don't know why you're getting so deffensive. I'm guessing you are good at what you do, whatever that is. Chemistry isn't my hobby, or pasttime, or something I dabble with on the weekends, it's my job, my career, my livelihood. I'm not an engine builder, I'm a chemist. The question was asked if the methanol goes bad, and I said no.
Then someone posted that his methanol got cloudy, so it had to have water in it, which is as far from the truth as you can get. You cannot do a visual test to determine water content, period. Cloudy methanol is usually from being mixed with something else that's not readily miscible, and methanol mixes quite well with water. If a water/methanol mixture looks different than the two starting solutions, then you've got contamination in one of them.
Let me ask this, do you measure TOC in the water you use? All DI water is not equal. There's DI water, then there's pure, low TOC water, big difference. We fail our water if it comes back with anything above 8ppb of TOC.

I'm going to end my comments in this thread with this....
1. He's using the water/meth as a secondary source of fueling, and primarily as a charge cooler to cool the air going into the motor while supplying some extra octane, that's a big difference to using it as your primary fuel source.
2. I'd be much more concerned about the gas sitting in his gas tank over the course of the winter/summer months as gasoline breaks down after about 30 days and starts dropping octane points quite quickly after that time frame. When I worked at Sunoco, we did quality control tests and saw quite a significant drop off in octane from 30-45 days.

I know what a hydrometer is I have a 175 gallon saltwater reef tank. I know all about using SG hydrometers (I'm guessing you mean the one with a swing needle in it) yea those are way innacurate. Although if the whole barrel has water in it it doesn't take a chemist(sorry alchemist no pun or harm intended) to know that the SG will be way low due to fresh water contamination.
A refractometer will tell you the SG down to .000 at least on the one I use for my reef tank.

I can see both sides to this arguement and it kinda started I think when I said the comment about it being water/meth injection as a joke.
If it's 10 bucks worth of gas throw it out. If it's a 50 gallon barrel I can see how you'd want a professional opinion on whether it's bad or not.
If it just has pure water mixed in with pure meth it will be fine, but if it's cloudy its contaminated from something other than water. I think this is the point Alchemist is trying to make.
