Common sense tells you shenanigans are occurring when one engine specs 5w-20 and the exact same engine in a very similar application spec 5w-50. Track pact sports an oil cooler which should make the need for heavier oil even less likely.
I'll take the education, training and experience of the people who actually built and tested the engine over "common sense" offered by some anonymous user name on the internet.

While within the warranty period (and if you care) of course use the factory recommended oil. Anything else risks an expensive lesson.
Out of warranty you can fool around a bit once you know temps and pressures. Anything else is guessing...
Exactly.

I still think it's yet another perfect fit for M1 0w40.
Please post the details of your education and experience in automotive engineering, and the work you have done developing this engine. That way we can decide whether to listen to you or the Ford engineers. Or, buy one of your own and take the risk of following your advise yourself.

Next time I take it for a spin, I will keep an eye on the oil temp when I run her hard [acceleration wise vs cruise] I do know I wait till she is completely warmed up before I get into her. Offhand I want to say the oil temp runs between 200-210..but will confirm

Hey brother, what temperatures do you usually see..it looks like it bleeds of heat rather quickly..any mods on yours?

It appears to be a coolant/oil heat exchanger, which explains the lack of a thermostat. The coolant will aide in heating the oil when cold and cooling the oil when hot.

Only mod so far is a JLT separator on the passengers side. I have the FRPP brake cooling kit and BMW front and rear driveshaft loops to put on at some point. The OE temp gauge does not really give a temp, but even with driving mine hard it has never had any heat issues.
For anyone wondering, here are the gauges I have been talking about.

I hate Ford uncalibrated gauges. Some on the Mustang sites say they're not even real transducers but a switch.
Regarding warranties. When I bought my 86 Grand National, the dealer made me sign a paper that said I would run a straight 30W conventional oil. I signed it but, thought that was incredibly stupid and decided to run M1 15w-50.

Do the GT and Track Pack both spec 75W140 in the rear diff,or does the regular GT spec 75W90?

About the oil,what about M1 15W50 (which is dirt cheap via Walmart 5 quart jugs) to satisfy the 50 weight requirement once the warranty is over? Are your oil changes free while under warranty,or so you have to pay extra for one of those maintenance packages to get *free* oil changes?
What gains are there in running 5w20, 5w30, 0w40 in this engine with the Track Pack?
And contrary, what are the negatives of running a ford approved 5w50?
In your shoes I would rum the MC 5w50 without any concerns. Instead of looking here for answers to a question that is clearly answered in the owners manual (Ford approved 5w50), I would be looking at FordRacing parts:

Congratulations, it's a beautiful car!

I searched through the UOA's for MC 5W50 and they looked perfect. Looks like excellent oil. If it were available at Walmart I'd use it in my car.

perfect my [censored].. did you go the the svtperformance link I posted? shows the motorcraft shearing massively to a 30..

Were they on raced/abused oci's or daily driven? My car sheared RP 20W50 down to a 40 weight within 3000-3200 miles,but my UOA was impeccable. Did the UOA's on svtperformance have a lot of wear metals?

Both spec 75W140 with the XL3 friction modifier. That being said the Track Pack does not need the modifier because it uses a Torsen differential instead of a Trac-Loc clutch type.

Luckily the dealer cannot require you to run anything, only GM could have done that and it would have required a statement in the manual like Ford has done here.

And I can show you UOA's of TWS 10w-60 shearing to a light 40 in no time flat. It doesn't change the fact that various aspects of the product (like HTHS for example) don't correlate directly with KV, so while the base visc may have sheared out of grade, the HTHS will still be relatively high.
M1 0w-40, the SM version used to shear like crazy too in certain applications. However that didn't stop Porsche, Audi, Mercedes, Chrysler....etc from recommending and using it in their most demanding and high performance applications.
I'm quite sure that with many of these oils that we observe shear in and run around like Chicken Little that this is actually part of the designed behavior. Remember those engineers I mentioned earlier

This is true.
Despite fuel dilution and other issues there is nothing to indicate any real problem.
Just to us oil nerds...
