Am about to change the oil in the trans of my 89 syncro westy.  My very
trusted mechanic usually uses Valvoline 80-90 wt gear oil that is approved
for GL-4 or GL-5 applications.  Having read your notes (as well as most of
this thread), I know I need GL-4.  So, I guess this stuff is not OK?  I know
it's a hypoid oil though.  Isn't that the point?

Problem is finding Redline MT-90 in Hilo, Hawaii (the Big Island).  Read
"the middle of nowhere."  I know it's available on the mainland (the REALLY
big island, as we call it), but shipping from there will be ridiculous, if
even possible, eh?  A hazardous material I'm sure.

OK... since I wrote the above I have called three auto parts places... NAPA
didn't know what I was talking about.  ASC was helpful and had a straight 90
weight gear oil, but it doesn't say on it whether it's for GL-4, GL-5 or
what.  The local VW dealership on the other side of the island (100 miles
away - there isn't one here) carries only the same Valvoline 80-90 wt gear
oil I mentioned that my mechanic uses.  Now what do I do?
