Nitrogen tires

I have seen claims that filling your tires with nitrogen will net you up to +20% MPG and some how the pressure doesn't change with temperature and it some how doesn't leak down like air (ha!). As if nitrogen is some how exempt from Boyle's law.

Back in 2006 I tested it and saw no improvements in fuel economy and charted pressure and temperature changes on par with air. Who would have thought since nitrogen only makes up 78% of air?

"Nitrogen filled tires" deserves the place of shame at the bottom of the wiki mod list page.
