How much diff fluid does the Moser 12 need? I just had to pull the cover off my Moser 12 bolt after whacking it one to many times on the underbody which caused it to leak. I laid down some red RTV and torqued it all back down. It took 2 quarts of 80w90 plus the posi additive and still wasnt full filling it from the front. Does it need more than that? Thanks in advance for the help.
I think it was somewhere in the 140 range though. And yes, I am using Mobil 1 synthetic...

Thanks. I put in 2 bottles so I guess I should be alright. Also I got an email back from Bruce Wood over at Moser who said the proper oil weight to use is 80W90 non-synthetic. I asked him if using thicker will quiet it up a bit and Im waiting to hear back.
