Hi,

Halfords gear oil EP 75W/80 GL4 okay for 1968 Morris minor Diff??
I know it says to use EP 90 but cannot find that locally, does it make make difference?

Halfords do an 80W/90 GL-4 that would be better than the lighter weight 75W/80. They do either their own brand or Comma.

EP90 freely available around here. Do you live even more out in the sticks than us?

[SteveClem]

Mind you,l get it from the local agricultural engineers. Guess it's used in lots of older tractors etc.

A straight EP90 is also fine - just make sure that whatever you get is GL-4, not -5. The -5 version is reputed to 'eat' yellow metal very quickly - there are bronze thrust washers behind the diff planet wheels.
