Message	I have been using Red line 75w90NS in my r200 differential which has a Quaife LSD installed, and does not require nor is it recommended for use by Quaife. They do recommend a GL5 gear oil which the 75w90NS is. Red line states the NS oil is a GL5 oil designed for transmission and transaxles requiring a GL5 lubricant.Extreme pressure additives allow for use with hypoid gears such as in a differential ring and pinion. Friction modifier can be added or used to customize limited slip diffs.
