Diff oil for 93 Def

[Lost Landy]

Hi all jsut ask what the best oil for the diffs in my 1993 Defender as it looks like the pervious owner used a red coloured oil and I think the grade is far to light??????

any 80/90wt gear oil is on the money.

avoid the kmart stuff but even that wont hurt anything.
