Default Does 50/50 Meth 'Go bad'?

I have a roughly 50% mix in a AEM 1 gallon sitting in my trunk, been there for about a month and half, the container was about half full. I literally didnt drive the car for a month and half.

Ive read that it can go bad and that it also cannot go bad.

IIRC the lid of the AEM 1 gallon has a tiny hole (I am guessing a breather)

Did my 50% mix dilute itself from absorbing moisture when it was sitting at the shop garage?

I have a 5 gallon drum of 100% pure Methanol, sealed and everything, good idea to just pour in straight meth into whatever mixture I have?

You can snatch a hydrometer for like $10 online. It's a super simple test for the future.

I highly doubt it's bad. Considering it's 50% water anyway. It won't be looking for extra water quite as aggressively as straight Meth.

I'm sure there technically would be some change if it was measured.

I have twin one gallon tanks, 50/50, and don't normally refill very often-couple months?

I've never seen a big enough change in my AFR's to suspect anything with the fluid...

I noticed my STFT (WRX 15) being positive, when they are normally negative when I have meth running

It only has half a gallon left, Ill pour in like 36 oz of pure meth and see what happens....
