Yea the local places that do fills usually charge an arm for what you get and its never pure enough nitrogen. There is always moisture in there

Unless the gas got contaminated, there shouldn’t be any moisture, as in dewpoints below -50*F. Granted the quicky lube’s evacuating/purging/filling procedures might not be the greatest…
But not having any moisture is the whole benefit. Who cares if you have 78% nitrogen (air) or 99% nitrogen, right? It’s the water vapor that’s doing most of the expanding.
