Can someone tell me if this is anything other than a white elephant? Snake oil, perhaps? Can this really save you gas over just monitoring your tire pressures? Is it actually safer than that incredibly flammable and explosive air that I'm currently filling my tires with? I mean, if Nascar is whoring it, it must be the real deal, but still, I'm skeptical. What do you all think, any legitimacy here?

It's a more pure nitrogen blend than air for your tires. Its benefit would be that it does not expand as much as air due to much less water that can come from regular compressors. I run a similar product, Nitrofill, in my tires because I have it available @ work and other than my recent episodes with fluctuating tire pressures, due to a faulty valve, it tends to keep a more stable pressure, which is a benefit to those of us that run higher than rated psi's. Just try not to pay to much for it, or befriend a tech and pay them on the side.

Alot of times that comes with some kind of roadside assistance plan or something, just be wary of that.
