Rear Differential Fluid

Is there any special kind out there that doesn’t cost an arm and a leg? I have to pull my cover off and figured while I am changing fluids I might as well put in some good stuff. Is there a such thing as good diff. fluid? I’m just un aware so I’m looking for advice. Thanks.

redline

just use napa 80-90

mobil 1 and use the gm rear diff additive or a good copy like k&w

no^

Do they sell these at AutoZone or something? I know Napa is probably only sold at Napa

get the napa or gm

cool, thanks. How much does a stock s-10 axle hold?

2 1/2

quarts?

sorry,yes

85w145 with about 8oz of ford friction modifer works like a charm…
