I just wish they would link to my site. It is prety much a given that your FE will increase 10% (which even on a guzzler would be > 1mpg).
No, this isn't an ad. I just hate it when people talk about such a paultry number like 1mpg. I beg any of you that have settled for what you get in FE to read the posts on GreenHybrid and to do a google search on improving your FE. And of course visiting
www.cleanmpg.com wouldn't hurt either ;0)
