Sorry I hit send too soon --
FWIW: Dennis Q. told me ( 6-1-10 ) to not use synthetic oil in the ZF -- he sells and uses ( even in his race cars ) Pennzoil stock #4096 SAE 80W-90 GL-5GEARPLUS Multi-purpose Gear Lubricant.
Bud #3400 ( Drive it like there is no tomorrow -- for there may not be ! )

Mike,
Okay, I just opened the ZF manual for the Dash-2 that I have and it
says "Mild EP gearbox oils of viscosity class SAE 80 should be used.
Mild gear oil types are those EP oil grades which in the presence of
condensation do not cause
corrosion on steel and non-ferrous metal
parts and hardening of gaskets and seals. The oils must meet our
Lubrication Requirements for ZF-Transmission Nr. 13-118. Under these
conditions, EP gear oils SAE 80 corresponding to specification
MIL-L-2105 (A) can be used. In case of doubt, check with the oil
supplier or ask our after sales service for the ZF-Lubrication List for
ZF Synchro Gearboxes".
I didn't see any reference to GL-5 in that but I'm not an expert.
Just food for thought, here's a possibly related discussion that I got
after searching the 'net:
[1]http://www.ratwell.com/technical/GearOil.html
Interesting but part of the webpage contradicts Lloyd's FAQ reasoning
about hyphoid and spiral bevel gears.
Maybe a call to Lloyd B. or Dennis Q. would help here. A friend of
mine likes the Penzoil synthetic GL-4. I have Brad Penn GL-4 in my box
currently. I'm definitely interested if Lloyd or Dennis say otherwise.

with GL4.
Then, and only then, did I RTFM!!! :>)
The Pantera owners manual very, very clearly states that GL5 is the
lube of choice.
I looked at the RBT recommendation for GL4 but I think that is
specifically referencing the new gearboxes he is building now,
rather than our 'classic' gearboxes. The new ones have very little
parts interchange with the old ones, believe it or not, being more
closely related to the BMW M1 version of the ZF. They are a
different animal, with different lube needs.
Or so it seems to me....
