Re: Differential oil used
I did my own research, looking on the Mobile site, found 600W, saw that it's uses are for steam cyls, and worm gear drives, then I found the 600 series of gear oils, they are listed for spur, and bevel gears, bI bouight a bucket of 636, it looks, feels and smells just like what I found in old untouched trans, and rears, and I have taken apart many bad engines that were full of STP, but I have never found it in good engines.
An old time used car guy told me his "secret" mix ---banana peels and sawdust!!
