Those companies that sell various gases in tanks have a bonanza. Oxygen, hydrogen, nitrogen, etc. Just separate it and bottle it under
pressure....


I laughed some time back when my Jeep got new tires. Cute little
green caps on the valve stems denoting they were charged with Nitrogen.


Oh, the majority of our atmosphere is Nitrogen....


The little caps eventually succumbed to UV, I guess. Replaced with proper metal ones...


I've no idea s to what the shop pumped into the tires on my Jaguar???


Priming rebuilt SBC's is a more or less standard practice. A drill and a shaft into the cavity for the distributor.


I just missed a device that primed engines. Swap meet. A guy before got it...

We all know that GM built millions and millions of SBC and BBC engines. Guess how many of them were pre-oiled before first start up?


None.
