Lucas oil treatment - 100% in differentials?

[Curtis]

I was reading a bottle of Lucas oil treatment the other day.
- I use it in my 72 Buick

Anyway, it says on it that you can fill a differential with 100% Lucas

Anyone do this or hear of such thing? I would imagine the slimy stuff would protect very good.

No way would I do that. From what I have seen with the Lucas additive, It would just ball up like a big chunk of honey around the ring gear and pull it away from the axle bearings and pinion bearings.

yeah, by the way that it clings to the gears on the display in I can imagine the same thing happening....

I did just check the website for Lucas, and it stats 50% in differentials
