The Owner's Manual states that the Rear Axel capacity is 1.69 qts of lubricant and 4 ounces of Limited Slip Additive.

Didn't anyone on this Forum get an Owner's Manual besides me??? :confused:

I get exactly 2qt's in my diff but I have a diff cooler with lines and pump which needs some extra oil. I have used RedLine 75W90 since day one which have limited slip addetive on recommendation from DRM.

:cheers:

Second differential lasted only 5 years, first one nearly 15. Has a cooler,and change every 3 track days. Maybe overkill, but now have a hellacious whine. always put in early 2 qts and the LSD additive, unless the lube I bought already had it in it. anybody else tracktheir cars and have short differential life?

No wonder you're having issues. NEVER give your diff LSD!!!! It'll take a trip, and never leave the farm!!!!!! I'm joking, obviously! Sorry, couldn't resist!!!!
