Royal Purple Diff Fluid
Anybody use RP diff fluid. It supposed to have the friction modifier already in it. Only found two threads mentioning it. Just wondering if there is chatter with just RP and no additional friction modifier. Or should I just use the Motorcraft stuff? Manual says 2.7 liters, does that include the friction modifier or is it 2.7 liters plus 4oz of friction modifier.
