Hi again Volks,
    I have been learning a little about rear end and manual transmission
lubricants. It seems there should be a difference between api gl4 and gl5
and how some companies label a products with both is beyond me.  Here is a
note from the mobil web site on the subject.  If I read the following
correctly mobil gl5 is ok to use in a rear axle but not a transmission that
requires gl4. Since our vanagons use a transaxle where  the rear end and
gears use the same lubricant we best use an api  GL4  rated lubricant as
Todd Hill seems to be trying to beat into our thick heads. Thanks Todd.
Hope this help clear this up for others.

Application
Mobil 1 Synthetic Gear Lubricant is suitable for all automotive applications
where lubricants meeting MIL-PRF-2105E, API Service GL-5, are recommended.
It can also be used in rear axles where an API Service GL-4 lubricant is
recommended. It should not be used in transmissions requiring an engine oil
or automatic transmission fluid, or GL-4 performance level.
