Eaton H052 Differential Oil?
'67 Chevy C20, Eaton H052, 4.11 gears. Trying to get this right:
* Correct capacity of oil? & ** Do I need a friction additive/modifier like LS additive? Factory manuals were written before synthetics and now also list with friction additive. I grabbed Mobile 1 Synthetic Gear Lube, LS 75W-90 before I realized what "LS" meant.

Re: Eaton H052 Differential Oil?
You don't mention a posi, so you probably don't need a friction modifier.
It's been long time since I had a HO52, so I don't remember the capacity. |

Re: Eaton H052 Differential Oil?
Mine took exactly 3 quarts, and I used the same stuff you bought. "LS" works just fine in an open diff, btw.
fwiw, use Permatex 81182 with a gasket to seal it all up. It's made specifically to work with gear oil.

Re: Eaton H052 Differential Oil?
Just make sure it's GL-5 rated oil.
