how do these oils perform in 3000 mile OCI's compared to Motorcraft blend? Have been a big fan of Valvoline for a long time.
thanks

For 3000 OCI it won't matter. Why not go 5000? Motorcraft is highly regarded, but so is Pennzoil YB. I have nver used Valvoline, but I am sure it is just as good.

Exactly my thoughts.
Any of these oils should be good for 5K/5months in a good running vehicle. If I had to rank them it would be 1)PYB 2)MC 3)Valvoline...but that's just my opinion.
I also believe that for a 5K OCI these will serve you just as well as a full synthetic oil.

I dont think anyone is putting these UOA on a spreadsheet - so no aggregate data on which to perform analysis. So, run what you want.
At least in the cars in your signature, any of these will dominate a 3000 mile OCI.
5w-20 is a very stable oil v. 5w-30. No need for 3k OCI unless short tripper in cold climate with low annual miles/kM driven. Because of it high VI, I suspect 5w-30 to be more unstable than 10w-40.
I'd prefer the PYB, but both are good oils, and can be run to at least 5k. Also consider Havoline, good stuff as well!
I would run the MC especially in your Ford, you can see by my sig I like Valvoline but when it comes to 5w20 I like an oil "made" to Ford specs rather than "meeting" the specs.
cant go wrong with any of them though.

For WSS IIR the oil has to meet certain specific wear areas for certain ford engines and sludge and deposit requirements and provide photographs as incidental proof. I dont think oils are "MADE" to ford spec - but if formulated well it will be built to "MEET" them. It highly likely that high performance synthetic oils may far exceed the C-P oils that "barely" meet a specific WSS criterion.
example:
3.2 PERFORMANCE
Shall meet all the requirements of the “ILSAC GF-4 Minimum Performance Standard for
Passenger Car Engine Oils" plus the following:
3.2.1 ASTM Sequence VG Test
Follower Pin Wear, average 30 mm, max.
(Cyl #8 intake and exhaust)
Ring Gap Increase, average 225 mm, max
(Cyl #1 and #8)
The following photographs of the VG test engine are required:
· Rocker arm cover and camshaft baffle
· Oil pan and baffle
· Oil pick-up screen
· Cylinder block underside
· Cylinder head valve decks
· Cylinder block front
· Timing chain cover
· Average and worst piston skirts, thrust sides
· Rear seal housing
