Is this much tire air loss normal?

Yeah I am too obsessed with it right now, just like I am with having my first new car in 20 years....
My car was built on 8/25/08, had 25 miles on it for the year it sat at the dealer before I test drove it on 7/31/09. It had the low tire indicator on when I test drove it complaining about one of the rear tires. Dealer put some air in it since it was off when I drove the car home 5 hours later (what a long day that was....). On 8/2 the first Onstar diags were run, it said 3 were low 3-4 lbs, one was low 5 lbs. I filled them all to 36 later that day. I use a old fashioned stick type gauge (have had the same one for 20+ years) to re-check the pressure (don't trust gas station built in gauge). For the next few weeks the pressure really stayed consistant, till we took that trip. It had been many years since I had been through wine country etc, between those roads and the ones near Rio Vista, really crappy examples of our tax $ at work...

If the atmosphere is 78.0% Nitrogen, 21% Oxygen and 1% Neon, Helium, Methane, Krypton, Hydrogen, Nitrous Oxide, Xenon, Ozone, Nitrogen Dioxide, Iodine, Carbon Monoxide, Ammonia, when you have a 22% loss off tire pressure, is all the oxygen gone?

I know better than to get in that with you!
I know what I'm told by the tire manufacturers and thats it. As to as to the actual size of the molecular structure; beats me. Maybe you as a superior mind would have a better explanation than myself or even Chevymgr's response. Anxiously waiting your response.
