Isn't that misleading? After all, if you fill up with the free stuff - air - it's 78% nitrogen anyway, so are they saying it's the ~21% oxygen that actually escapes? Sounds like marketing hype to me!
Simple answer, whenever you fill up ya tank, check ya tyres - simples. If you can't remember to check your tyre pressures, you probably shouldn't be in charge of a car...!
