LSD & gearbox

[blackers999]

Hi there have just installed a Harold hockey plated diff just wondering if anyone knows what sort of oil I should put in the box for the best outputs and life from it?

Forgot to say it is in a fwd corsa f13cr gearbox

Hi,

I have same diff in a Quaife F13/15 box in my rally Nova and have always used Castrol B373. Have had no issues and it's reasonable price and suitable for the LSD.
