Diesel Max
93 F-250 4X4 - 7.3
Two questions:
I have a 10.25 limited slip diff with 4:10's. If synthetic oil is used, do you still need to add the friction modifier ? Is 75W-90 the correct oil for this diff ?
I have a ZF5 trans. Is regular Mercon ATF ok for this application or should it be Synthetic Mercon ATF ??
Thanks for the input
