This may sound silly, but it is an honest question. Do you think it would be OK to run Motorcraft Oil in a GM V6 engine? The Motorcraft brochure states that it is targeted for Ford/Lincoln products, but does that mean that one should NOT run it in a GM engine? To me, a Ford engine and a GM engine would require a similar method of lubrication. Also, if you can run Quaker State in a GM and a Ford, why not Motorcraft oil in another mfgr's engines?
