There is only one appoved set of applications for the use of Auto-Rx. This set of applications is the only one guaranteed to work, or your money will be refunded. The application procedure can be found on http://www.auto_rx.com only. Anyone posting an alternate application is misinformed. We have had several different application ratios tested and the one which I am most comfortable is 4 ounces of Auto-Rx for a "sludge engine" maintainance dose. Please click on the Auto-Rx tech board for cutting edge input. You will find this on the header of the Auto-Rx web site.
