The FBO didn't completely fill up the tank (1700 psi) before I left

I take it you can tell beforehand from the pressure gauge? Why wouldn't
they fill it completely?

I have frequently run into FBOs that can't supply a full 2000 psi of
pressure. Why this is, I don't know (I mean, I understand the mechanics of
it, but why they maintain their oxygen supply at such a low state, I can't
say). But it's actually unusual for me to get my tank actually filled with
a "fill-up".

By the way, the range of prices I've seen only has a passing relation to the
amount of oxygen I get. Of course, I don't pay full price if I don't get a
full tank, but sometimes I can get a full tank (starting from nearly empty)
for a low price.

Pelican's Perch #13:
Getting High on Welder's Oxygen

Having problems finding Aviator's Breathing Oxygen to refill your bottle?
Upset about the rip-off prices some FBOs charge for an O2 fill? Don't put up
with it, says AVweb's John Deakin, who explains why it's perfectly safe -
and perfectly legal - to use cheap welder's oxygen, and tells you exactly
what you need to know to buy it in bulk and do your own refills.

They were getting ready to close and would have had to retrieve a fresh
tank. 1700 was fine this time.

Mine is rated for 3000, but I can only rarely get that. It is a
fiberglass wrapped bottle.

Typically they are 1800 to 2400 depending on temp and cylinder construction.

The MH is very deluxe. You feel great on about 1/4 the oxygen
that would usually be required.

Probably not for the casual user tho... It would take a lot of fills
to justify the price.

The reason why it is popuar among glider pilots is not economics, but
convenience and safety.

Convenience: Put the cannula and turn the system on before you start and
forget it for the rest of the day.

Safety: Because it uses very little oxygen, we can use it at lower
altitudes without the risk of running out of oxygene. Many of us set the
threshold as low as 6000 ft. Believe it or not, but we think we feel the
difference. (Less fatigue, no headache the day after, generally better
flying.) Of course, glider flights differ a lot from powered ones: the
duration of glider flights is typically somewhere between 6 to 8 hours
and at very varying altitudes.

Another question that hit me (without getting into the whole aviation 02 vs
medical 02 vs welding 02 debate)

What is the average cost for your refills with aviation 02?

By the way, all the vendors will top off your bottles for free at
Oshkosh (and probably the other major shows). Handy thing to remember.

Because they either don't have a cascade or don't know how to use it
properly. They probably stopped at 1700 because that was all that was
left in their single bottle.

I wonder how much was paid out in that law suit?
