For you mechanics

Costco uses only Nitrogen for their fills and refills.
They have a machine that strips out the oxygen.
It's almost identical to the gadget that people use at home to concentrate oxygen.
However, in this case the oxygen is discarded instead of the nitrogen.

I used to work on the machines that separate the oxygen and nitrogen and then purge the oxygen and store the nitro in large cylinders. the nitrogen molecule is larger, the difference is very small, like one atom difference small. the nitrogen tire will still loose air but at a much slower rate. I think its 1/3rd slower then air so while its false that it never needs to be topped up but true that it will last longer and fluctuate less.

Get this my sister in law took her 2016 Rogue to a reputable tire shop because the indicator showed a low tire . The tire was 2lbs low so before the mechanic put air in the tire he asked " do you want regular air which is free or oxygenated air at $5 @ lb". What the crap, is this correct or a scam, can someone explain?

Unless their "nitrogen process" is
absolutely totally free...
Tell your sister to save her money,
and just check the tires' pressures
on a regular basis---(that's where
you can help her out a little bit).

Just put plain ol' air in it.

Put the "free" air in and check it more often.

I opted to use hydrogen... I just have to avoid pot-holes.

No one caught my feeble attempt at levity??? :-)

I think we just assumed it was a hyper-miling technique.

[MattPersman]

Agree unless it's free and doesn't take any extra time pass it. Regular air is 79% nitrogen approximately anyways. Usually other sources of leaks before air molecules are a factor.

I have a nitro machine and don't even use it in our personal cars.

If you were doing the salt flats at 200 maybe it would be more stable or something but daily driver pointless just another $ making selling tool.
