Not sure how i missed this earlier....Alt.ImaCoupe wrote:
Actually it does make sense, the two nitrogren atoms in N2 are triple bonded whereas the two oxygen atoms in O2 are essentially double bonded because of the number of electrons in the outer orbits of the atoms. That makes nitrogen more stable.
Oxygen cause thing to oxidize, one form of which it rust, and therefore the issue with the rims. The science is solid on this one, whether it makes enough of a difference to justify the money is another question.
ALUMINUM does NOT rust. All metals oxidize, but only iron and steel oxidize to the point where the metal changes color and "flakes" off - which is what we know as rust. When alumiunm corrodes, it turns into alumiunm oxide, which is a very hard compound that protect the alumium from corroding further. You probably won't even notice this occuring as well, since it still retains the same general color of aluminum...
SBD - keep us updated on your mpg gains. It still blows my mind that this is going to increase your gas mileage, but I'd like to see what happens.
