<x-flowed>>Started checking around and there is a 'new' standard for GL5 >which is GL5 - MT1. Penerite here in Oz has a 80 w 90 GL5 - MT1 >available and the manufacturer swore that it was suitable for >(in fact developed for) trannies with copper/brass/bronze components >(Copper alloys). >Even says so on the back of the bottle! If I remember our recent discussion correctly, copper is not the issue, as bronze and brass both have copper. The issue is the percentage of *aluminum* and *zinc* used in the VW brass alloy, and that conventional GL-5 lubricants seem to have adverse effects on the Al and Zi. The question that remains unanswered (I think) is the compatibility with the synthetic GL-5 lubricants. -Mark Fuhriman _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp. ------------------------------------------------------------------- List info at http://www.vwtype3.org/list or mailto:help@vwtype3.org </x-flowed>
