So you are using 100% nitrogen where there is substantial benefit, just like aircraft use nitrogen in their tires where there is substantial benefit.

My issue is the practice has spilled over to car tires where resellers knowingly or unknowingly "put their blinders on", and peddle the stuff. In other words it's an upsell item with no value to the end user. At least if Domino's upsells by asking "Would you like breadsticks with your order?" you get to eat the breadsticks!

And BTW I'm not just bashing nitrogen in tires. With few exceptions I have the same opinion of any oil, transmission, coolant and gas tank additive on the market.

I have extensive experience using nitrogen inflated tires. The whole point, in my own use in tires on a road racing car, the point is to minimize the tire pressure increase as tires get warmed (hot) on a racetrack during the first few laps of a race...According to my notes, my rather large (12.5" of tread width, slick and soft) gained close to 5psi when filled with compressed air...When filled with nitrogen, the pressure gain was only 2psi...allowing me to start races closer to the proper tire pressure and hence NOT lose positions or crash during the first few laps as my tires warmed up to racing temp... The 'science' behind this is said to be mainly because bottled nitrogen is almost 'dry' while atmosphere from a compressor contains ambient humidity...and the internal water vapor turns to steam as the tire gets hot...causing a rather substantial pressure increase.... Dunno about the 'science' but I do know the numbers that I have recorded are quite valid...having kept a close record over about 6yrs of track time and many different tracks. I was using large cylinders like welding tanks....refillable at welding supply houses for about $25 each and they would last me about 20 races.....You can also use the compressed gas to power air tools when away from a plug in.... For a Vanagon?....no reason to use it...
