Hi all
What is the best grade of oil to use when changing the oil in the diff? Is it something like Penrite Hypoid 80W-90?
Cheers

Salisbury reccomended that I use EP140
Apparently it works better with the tooth profile and sticks to the teeth longer. They told me that the biggest problem with these diffs is condensation rusting away at the of teeth that are not submerged in the oil.
I got mine mail order from FROST.
