Hey all, just drove up to Lansing, MI and picked up a 4.10 LSD from an iX from AWDE30. I will be installing it in my 88 325i cabby. I know people have used 80W90 in these, but I have also heard that BMW is now recommending 75W140??? Should I also add some limited slip additive?
Thanks in advance for your help!
Brian
