I use Lucas Gear Oil with GM Posi additive in my S60. That is what Strange recommended and strictly forbid using synthetics. Since a locker is not a really a posi unit, you may not need the Posi additive.

A quality petroleum/mineral based oil works best in the Detroit Locker units. Do not use synthetic oil. Friction additive/modifier is not required.

Which posi unit is in Your S60? If it is the Truetrac or the S Trac no posi additive is required.
