I have a Ford 9" shortened can some one tell me how much fluid it takes? This has the big fill hole near the top. Also what do you recomend. This is a Strange center section with a Detroit Locker?

Also what do you guys use for engine oil? Its going in a pro street with a 502

thanks

I run 2 bottles of Kendall 75/140 oil in my 9" and 20/50 would be fine in the 502.

a quality 85-140 multi viscosity, mineral based, non synthetic would be good on a new assembly for a few hundred miles.. change it...after that , some folks use a synthetic, or just go back to a fresh charge of what you used before.

pour it in the top filler untill it either runs out the side filler port ( if so equipped) or untill it just starts down the axle tube ( requires one axle to be removed )
