Should i add lucas to my differential ?

I know this might sound like a "fishing story", but it's true.

Anyway... I had a 72 1/2 ton 2wd that had been run really, really low on rear diff oil - sounded like a jet at full throttle going down the road. I drained it & filled it will Lucas Oil Stabilizer & within a few miles it was almost totally silent. I ran it several years that way (prob 6 or 8k miles) - towing, scrapping, yanking, etc. It finally died when I got stuck during an ice storm & decided I'd get it out or break something. Ended up being the latter - came apart so hard that gear pieces dimpled the housing & it wouldn't hold fluid anymore.

I'm not 100% convinced that Lucas will do much more for your motor than slow oil consumption, but it was amazing what it did in that rear end.
