Oreillys carries Mobil 1 and friction mod.

The synthetic gear oil usually has friction modifier in it already.

SOME, i would not say usually. That sets the op up for another repair

If you can't find it locally, it's every where online. Motorcraft LS additive is cheap online. http://www.summitracing.com/parts/FM...6-A1/?rtype=10

Motorcraft 75w140 isn't necessarily cheap, but that's the way I would go.

RP, valvoline, most of the synthetics I've seen/used have had it. Of course, don't be a dumbass and not check.
