I've got a '94 F150 Lighting (5.8L; E4OD; 8.8/4.10 differential).
The gear lube is 75W-140 with the additional of 5oz. of Friction Modifier.
Is there an off-the-shelf equivalent or alternative to the Motorcraft Friction Modifier that will satisfy this requirement?
Preferably an alternative more readily/easily obtainable (i.e. A trip the parts store as opposed to a trip to the dealer).
