Quote: Local news article claimed 1-1.5 mpg improvement. Anyone here tried it ?
No, but I do religiously change the air in my tires every 3,000 miles.
do you use NOS air or reproduction ?
Reproduction. I pulled the original air out of the tires and store it in baloons in my garage. It's too valuable to use every day! I put it back in sometime for shows though--you know how those judges can be.
