You do know the air you breath is 78% nitrogen, right?

Quoted:
In before the "I only inflate my car tires with nitrogen because the bigger molecules don't leak out" foamers.

Quoted:

There is plenty of nitrogen in ammonia (or longer amine molecules) and this is an excellent carbon cleaning agent.



However, you will loose some MPG with this formulation.

Quoted:


Its true, plus the lack of moisture in it keeps the pressure stable on hotter and colder days

Starting today, all Shell gas stations will be pumping a new fuel: Shell's nitrogen-enhanced gasoline.

Before you start speculating about the wonder fuel of tomorrow, understand that this nitrogen-enriched gasoline differs from the gas Shell was pumping yesterday in its engine-cleaning detergents and additives.

Shell claims that its nitrogen-enriched gasoline cleans better than before and protects better against engine buildup. Of note, all three grades of gasoline will contain the nitrogen-enriched detergents, with its V-Power premium grade containing five times the government-mandated amount. The results are fewer intake deposits, cleaner combustion chambers, and less fuel injector fouling and intake valve sticking.

Citing the rising complexity of new direct-injected and hybridized engines, Shell also claims that this new fuel is better suited to the rigors of modern drive trains.

Considering that detergents and additives are federally mandated in the United States, and just about every brand of gasoline being pumped today makes some mention of the power of their detergents, we don't see Shell's gas as being very revolutionary. We're also inclined to believe that the "nitrogen enhanced" title is more of a gimmick than anything else. However, any step toward cleaner, better-running engines is a good one in our book.

Shell stated that it didn't expect this new nitrogen-enhanced gasoline to result in an increase in fuel price. But with gas prices being set by individual stations and changing daily, that will be nearly impossible to measure.

Quoted:

Another gimmick in selling gasoline. Gasolie is gasoline, the US EPA will see to that.

Quoted:


Up to the rack, it is all ASTM standard.  But individual brands CAN ADD detergents, ethanol etc as long as the AKI isn't decreased or other deviation to ASTM specifications.

Quoted:
Okay, since we are at it, how about adding some Trinitrotoluene or Nitromethane to the mix? That will definitely get you "more get up and go."

Quoted:


Nitromethane sure wouldn't hurt.

Quoted:
wifes car says only to inflate tires with Nitrogen.... Havent had to inflate them yet so Im not sure I buy into this.  Its a Saturn Sky...maybe its because of the tires being very low profile I dont know....but there is an air compressor in the trunk with fix a flat since there is no room for a spare... not a nitrogen compressor.

Quoted:









Doesn't nitromethane require cold storage?

Quoted:

Keith_J covered this a few weeks back in his technospeak gibberish. Basically it's a gimmick.





eta As you can already see. Damnit!
