Title: Differential Oil Post by: KFH on June 07, 2010, 10:12:45 PM Is it ok to use a 90 grade LS oil in the differential of an FC? I have 4 ltrs of it in the shed and would like to use it if possible. I spoke to the tech service manager of a dealership for a different brand and he said they use 85/145 LS oil in all the diffs, limited slip or not without any trouble. I know not to use ordinary diff oil in an LS diff.

The standard diff oil that was originally put in the early holdens was 80/90. I would think that the 90 weight LS oil would be fine to use in the early diff.
