In other words, if you live in the north, you get a better deal, year-round. If you live in the warmer south, you don't do as well. But there's probably little actual difference from month to month in the same area... at least not as much as that article leads you to believe. And especially not day to day, as the earth many feet down from the surface simply can't react that fast.
Hi,

Yes, but the Tanks are Vented and so pull in Ambient Temperature Air to offset the Gas which is pumped out. How much difference this makes probably depends on the Air Temp, how full the Tank is, etc...

Happy Motoring!... Jim'99
