Gear Oil and Additives

[USNENFTS]

Time as come to pull my diff cover, she be leakin! Just wondering what some of you use for oil and if it requires any additives. If I recall its 80W-90?

75/80W-140 for the Sterling. I'm using Lucas synthetic gear oil. No need for limited slip additives with a synthetic or blend gear oil. Turns out I didn't even have a LS (rusty cover tag).
