I'm not sure all engine oils can be mixed, well they can be, but I'm not so sure that it's good to mix some engine oils getting into boutique, and specialty oils.. but again heck I dunno.

As far as gaining anything I don't think you will gain anything if your trying to make your own brew so to speak, but if you have left over engine oil for sure clean it up I have run all kinds of mixes, and makes, viscosity etc when doing a clean up of stray oil quarts etc... I just think the oil manufacture is trying to establish a goal when making an engine oil, and when you mix engine oils to make your own you may in fact lower the goal that both engine oils are trying to establish.. if that makes any sense...

Now that said I think in many of the engine oil specifications that must be met with today's oil/oils that one of these is that the engine oils must be compatible with each other, so that is yet surely another way to look at it. Also no problem cleaning up any stray quarts
 
Go ahead and mix these two any way you want to.
Be aware that there are no guarantees that it will end up substantially better.

What can be wrong with that?...It is still Motorcraft...I do that myself sometimes when I use the Blend...It can only make it better!
