I am an Amsoil Dealer. I live in the Mansfield/Burleson area. I can be e-mailed with any questions. It is usually cheaper to become a dealer or preferred customer than it is to buy from a dealer. A dealer will have to sign you up... no big deal. I do not sell much of it at all... . just to a few people. I use it in everything with an engine around here. Most of my employees run it in their trucks with excellent results... . they are also dealers... CJ
