[6pack] GM or Pennzoil synchromesh (Gear Oil)

[Footfrek at aol.com]

I was in the  auto parts  store and saw bottle of Pennzoil for  synchromesh 
GM manual transmissions. I read that  it  was  safe  for  yellow metals. I 
was  wondering if anyone  was  using  this? It seems to be readily  
available at least. Apparently I solves   some  shifting  problems honda owners  
seem to  have.  Although that  may  only  be  the  friction   modified version.
