Morning guys. im refitting my diff today and wondered what oil i should use for it but im unsure if its a different spec as it has the ford lsd fitted. i could reuse what came out of it put i might not have enought and i dont want to then mix oils (not sure what was in it).

i have some comma 75/90W 5 gearbox oil but i dont want to stuff it in without you comments.

thanks

in my 3.62 LSD I used

Castrol 80w90 GL-5

Was £9 in halfords, £5er on trade.

Use the same as the open diffs. The LSD gubbins is in a sealed unit filled with some clever stuff and does not share the oil you put in the diff.
