[DeTomaso] ZF gear oil

[Corey Price]

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:
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.

   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:

   Interesting but part of the webpage contradicts Lloyd's FAQ reasoning
   about hyphoid and spiral bevel gears.

     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....
