which diff oil?
 

read that Castrol SAF-XJ is best for the bmw

again for the m3 race car.

I know of something better (IMO) give me a ring tomorrow on 01652 648429. I will tell you the price.....;)

Uh-oh, thats either gonna be very good (cheap) or very bad (expensive):hahaha::hahaha::hahaha:

Hi,

The Castrol is good, many of the E30 M3 guys running
LSD with 30/30 ramp angles and 75% lock
up use it.

I have run the Millers 75-140 fully syn in
my E30 M3 DTM Diff, but its very thick
that you can not use the diff pump when oil is cold.

The Motul 75-140 comp is very good but very
expensive.

Some swear by Royal Purple, both in their
Diffs/Boxes and Engines.

What put 'Oil' into perspective for me a while back
was that when talking to Tractive about what
oil we should use in their 6 speed Sequential G/box
they said '' Use Coma, and change it a little
bit more frequent''.

Regards,

The Gorilla.

It only holds about 1.5 ltrs so cant be that expensive!!! I can supply it if you require.
