Check this out.  I just got off the phone with Amsoil.  The GL-4 vs. GL-5 debate is officially over.  The problem has been rectified.  As long as the oil has been tested for MT-1 compatibility, it will work fine with "yellow metals" like brass/bronze synchros.  So, you may all rest assured that it's OK to put GL-5 in your tranny as long as it's MT-1 tested and approved.  Yay!  3 more bottles of Amsoil Series 2000 75W90 to go with my new B&M shifter please!!  <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt='
