I have a barrel of methanol in the shop that I bought in late 2015. It has had 5 gallons pulled from it but been capped tightly ever since.
Would it still be good?

and just how do you think its transported??? Yes sir nice big tanker trucks in any weather at any time. Then delivered to the bulk plant and the tanks there are never kept full...........starting to see the flaw in the advice you gave yet?Darin, assuming your drum has not leaked at all since you dumped 5 gallons of methanol you replaced it with 5 gallons of air.
Say it was a really hot humid day, if so that air could contain from 1-1.25 ounces of water. Since methanol is very hygroscopic almost all of that water is now part of the alcohol.
How much water is required to degrade methanol I am sure but you for sure have some in the alcohol now.
Most everyone knows you should only use brake fluid from a sealed bottle, yet these same guys will dump fuel from a 55 gallon drum on a 85% humidity day and not worry about it.
I have always been surprised that no one makes a kit to either add inert gas to the drum as you use the alcohol, or a kit to insert a bladder/balloon into the large bung that would be sealed to the cap opening to allow air to replace the missing volume of methanol yet not contaminate the methanol with atmosphere.
Sure an uncapped or loosely capped drum is much worse since it (the drum) continues to breath as it heats and cools but why add any air/moisture to the methanol to begin with?
Not at all, just because something is treated poorly during delivery is no reason to continue the trend.and just how do you think its transported???

could a person hook a vacuum pump and pull a vacuum on he drumDarin, assuming your drum has not leaked at all since you dumped 5 gallons of methanol you replaced it with 5 gallons of air.
