Do you mean oil? I just put a Eaton 3.73 posi in my 12 bolt and it recommended 80-90 weight gear oil. It actually said not to use synthetic oils. As for the posi unit itself Randys Ring and Pinion sent me some posi oil in a little bottle. The guy that set mine up recommended the Mystick JT7...in fact he said that is all he would run......
Hope this is what you were looking for.
