Greetings All:
I recall adding a foul smelling, small bottle of "whale oil" or "sperm oil" (seriously...!) into the rear differential in the late 70's the was purported to reduce build-up on posi clutches and generally quiet the rear end, keeping it well lubricated.
Does anyone remember/know if this or was I the youthful victim of the proverbial "snake-oil" salesman (even though I was a cop!)
If valid, anyone know where it's sold ??
Thanks-

It's sold at any GM dealer, tell them you need a bottle of positraction additive. If I can find the part number I'll post it.
Just bought some last month......

I remember it being called 'sperm whale oil' at one time also, but think the latest stuff is synthetic.

...so if whale oil comes from whales, then does that mean that synthetic whale oil comes from those inflatable pool toys? (hehe)

Whale oil was a particularly important part of auto transmission oil in the past. I quess it was important for the disc clutch packs, as posi's have. Now that whale products are not obtainable, I'm sure someone sythesiized an oil that does the same thing.
