Hello all off road & vintage vehicle owners.
I have a question for all those using vintage / veteran jeeps like the Willys or Ford
altered differentials & gear boxes.
What gear oil do you guys use in your tranny & differentials & have you ever had any problems with it ?
The reason to ask you all is that I cannot find a straight mineral gear oil that is required for older vehicles, as some components are made of bronze & copper in the tranny and diffs & the EP oils available in the market have sulphur that attacks these yellow metals and eats them away.
