[DeTomaso] ZF oil choice

It seems to me that when you combine a tranny and diff in one unit you're going to have to compromise on the lube.
Another choice would be RedLine MTL, Manual Transmission Lube, which is lower viscosity than the MT-90 and will give better shifting when cold. Unless you drive your car really hard you won't need the extra viscosity.

Redline 75W-90 NS is still a GL-5 gear oil. It does not have limited
slip
additives but it does have the additives that make it a GL-5,
which could
make it potentially corrosive in a ZF. I understand Les
Gray says it's
"great" but what effect would it have if used over a
long period of
time?
The two best GL-4 gear oils that I know of are: Redline Synthetic
MT-90
(75W-90) and Brad Penn (formerly Kendall) "Classic" Gear Oil
(80W-90,
mineral based).
You may notice our Pantera owner's manuals
specify GL-5 gear oil;
however, I've always thought whoever wrote the manual
made a mistake.
It's also possible DeTomaso's oil sponsor, Agip, did not
have a
suitable GL-4 at the time. To this day, Lloyd Butfoy still
recommends
the use of GL-4 gear oil.
