That is a GL5 oil. The Minor differential uses a GL4 oil.

GL5 oils should be assumed to be unsafe with the "yellow metals" that are found in the Minor differential unless the manufacturer specifically states that the oil is "yellow metal safe". The wrong oil can destroy the differential.

Millers Classic Differential oil EP90 GL5 specifically states that the oil is safe with brass and bronze.

Thank you will see if can get millers local.
Postage to n.i is a disaster. Also some confusion as to how much the diff holds , any idea , it’s a late model .
