Notes on Auto-Rx® and rotating seals

Auto-Rx® will clean rotating seals, removing the sludge and varnish that prevent rotating seals from working properly. Auto-Rx® cannot repair damaged rotating seals, such as those which have been torn or ripped. During the Clean Phase, rotating seal leaks may worsen. However, sealing ability should be restored during the Rinse Phase. In some cases, full recovery of rotating seals may not be achieved until several miles following completion of the last Rinse Phase.
