Nitrogen Promotes Better Gas Mileage

This NYT Article talks about things we can do to improve gas mileage, especially as we see gas moving toward $4 per gallon.  As mentioned in the blog before about tire pressure, "maintaining the proper pressure at recommended levels can really have an impact on mileage."  Since a nitrogen inflated tire mainains its pressure longer, improving tire life and maximizing fuel efficiency, this article specifically mentions nitrogen inflation as a "trick of the trade."
