Why does my car have green topped valve covers?

In fact nissan made a big deal when the GT-R came out about how they filled the tires with pure nitrogen because normal air was too "unstable". It would probably only ever make a difference in that situation because they are constantly recording data on the nurburgring trying to aim for consistency with variables and such.

Many places made a big deal about it at one time but it has sort of dropped off the map since several government studies showed it is meaningless in a normal car. I am not going to bother to link any because I am perfectly aware there are probably an equal number saying that it is god's gift to tires.
What it is good for is a cheap and easy upsale for dealers and tire places or else it would be gone by now.

Thanks!

PV=NRT
all these gasses act the same in regard to expansion by temperature
the only advantage is that water that has condensed inside the tire may change to vapor at a rate of 22.4 to 1

Bah screw that I'm not paying to fill up on nitrogen. Two tires dont even have caps. They probably all have air anyway

DO NOT use aluminum valve stem caps unless you want to Dremel them off when they seize up on you!

Then the individual 0 and H molecules take up more space than they did before.

Me too.......

YIKES, does that mean that the old air in my tires contains free hydrogen ... ??

What if it ignites, will my tires blow up .....

When I let air out of my tires, should I not have an open flame in the area ... ??

Should I put fresh air in my tires every now & then .. ??

We could fill the tires with water and run the engine with the hydrogen and oxygen.

YES!

All we need is a heat source to start the thermal decomposition of the water molecules. Let's see, I wonder if the heat off of a turbocharger would reach up to 1,000 degrees C to get it started .....

We just may be onto something BIG here ......

No no no.... youre doing that wrong. You need to use power from the alternator to dissociate water into H & O2, then feed that into the engine , recombust it, and make more power.
No really it works...... saw it on an info-mercial - they cant lie....

And as for the Air vs Pure nitrogen:
The ONLY benefit it gives you is lack of moisture.

The difference between pure Nitrogen and and a Blend of Nitrogen 78% and Oxygen 21% (Air) is in the noise.
Nitrogen & Oxygen are right next to each other on the periodic table.
(Atomic Mass only differs by ~10%)

Not to worry, they don't know about our secret catalyst

Well, justatroll, electrolysis of water would produce hydrogen ....... but that's soooo old school (must have been an old info-mercial).

We are waaaaay far advanced from that .....

Oh, BTW, we can't discover any more elements ...... because the bottom row of the periodic table is all filled up .........

Nitrogen is the only thing filled in commercial aircraft tires for a reason......yes its better i.e.......less effected by heat and cold cycling pressure changes....less abnormal tire wear....yes its the only thing I would put in my tires if I had the choice.....thats the catch though.....1...im not going to be seeking a dealership anytime I want tires serviced....2 Im not going to buy/rent bottles.....so pure air it is....
