I think the major reason that Ford pushes the MC 5w50 with a unique spec is to have people run a 50-weight oil with zddp content in the range of 600-800 ppm. Any other 50-weight oil that you're going to buy off the shelf is going to have more, then you run the risk of shortening the catalyst life. If the car is going to be run in track days, the catalysts won't last anyway, so it would be better to protect the engine with an oil with more stable viscosity. If I had one, I would not run MC 5w50 in it. I'm thinking something like PUE 5w40, AMSoil 10w40, or Redline 10w40. These oils start as 40 weights, and will remain 40-weights. The MC 5w50 starts as a 50-weight, and ends up a 30-weight.

the early 5w20 specced Coyotes had oil squirters, the later 5w50 specced ones don't. That's why.

there isnt. they're saying 5w50 cause the temps it'll see at track. but the motorcraft 5w50 shears.
here's a link to a thread on another forum that'll be very very helpful.

I just don't understand why people are so scared to run something other than what ford suggests. 5w50 is overkill. plus poor base stocks, weak TBN retention. poor shear stability.
It's the spec oil for an engine under warranty, it isn't that hard to understand really. And I'd love to know your reasoning behind saying it has poor base stocks. Most oils with a big visc spread shear, so that's not surprising. And it only needs to have long duration TBN retention if it is running drain intervals that call for it, if it isn't, it doesn't. There's no reason
to have an oil with a 25,000 mile TBN reserve being changed by the OLM at 6,000 miles.
I understand that. but olm I believe on these are 10k miles. and I see the 5w50 barely making it to 5k.
and if have a warranty issue.. drop the oil change it to 5w50 whatever. but that's unlikely to be needed.

Just to clarify, the LSD on the Track Pack cars is a Torsen T-2 not a Track-Loc clutch type. O and the differetnial housing is painted and has this bad to the bone cover.
Also the traction control programming is unique to the Track Pack cars.

Food for thought: This oil isn't a cafe-graded product going into a neutered engine, it is the spec oil for the Ford GT, GT500, GT1000, BOSS 302 and now the Track Pack GT. Why on God's green earth would Ford intentionally spec a sub-par product here?
Basically there are two conclusions to potentially be drawn from this:
1. Ford and their teams of engineers are stupid and have recommended a poor product that provides inadequate protection for their highest priced, most powerful cars that they KNOW are going to be used in a race track environment, one of those cars making north of 1,000HP.
2. We don't know as much about this oil as we like to think we do and Ford knows more than us about the oil requirements for the engines the design and build and this product meets ALL of those requirements, and that is why it was developed and recommended for these applications.
IMHO, the engineers at Ford aren't stupid. They've spec'd a lubricant they KNOW will shear intentionally and this is quite similar to BMW's 10w-60, which shears down into a 40 quite quickly as well. Since they have intimate knowledge of the true viscosity and other lubricating requirements of these engines I think it is more what we DON'T know about this product that is the real question here, because quite frankly it obviously is not enough given these types of discussions.

My only real gripe is the lack of approved options beyond Motorcraft. I know there is a Mobil 1 5W50, but it is not readily available in the US. The Castrol 5W50 does not have the correct approval spec, at least last time I checked. I really have no issue with the Motorcraft, I just like to have options if I am away from a dealer.

Yes, I think the only approved alternative is the QSUD 5w-50 IIRC.

I'm willing to bet they spec Motorcraft oil because it means more money for Ford,since it's a Ford branded product. The oil fill cap says "recommended" and not "required". As long as the spec viscosity is used,doesn't that legally fulfil the warranty concerns? Wonder how Syntec/M1/Redline 5W50 measures up compared to the Motorcraft?

It says Motorcraft on the cap because that's what they recommend, of course.
They don't spec Motorcraft oil however. They spec an oil meeting WSS-M2C931-B. Currently the only two oils on the market that meet it are QSUD 5w-50 and Motorcraft 5w-50.
That said, it appears the 2014 manual doesn't REQUIRE that spec anymore:

Does the engine require the heavier 5W-50 over the standard Mustang GT which is spec'd for 5W-20? For normal fast street use I'd say no. If you're not seeing oil temp's over 230F which the none track spec'd Mustang can generate without triggering the ECU safeties then I'd say the 5W-20 lube would be a better choice not that I'm recommending it during your warranty period.
As others have suggested I'd stick with the Motorcraft 5W-50 partly because it fortunately is very shear prone but that is nothing to be concerned about as OVERKILL has fully explained.
Between now and through the hot Texas summer I'd take the time to become very familiar with the oil pressure and maximum oil temp's characteristics of your engine particularly when you're really hammering it.
With that detailed info' then you can possibly revisit your motor oil choice.
If for example you cannot generate oil temp's over 230F I'd consider tracking down the right engineer at Ford to speak to and request permission to run a lighter oil grade, if not their 5W-20 perhaps their 5W-30? Who knows, you could get lucky and get a proper technical answer.

That would be great, good luck though. I'd be willing to bet, if the OP could even get an engineer to talk to him he'll be reminded about using the spec'd oil for the warranty or else.

All this teeth gnashing over warranties. Doesn't tracking the car void the warranty anyway.
If I were not going to track the car and were going to drive it within the parameters of keeping my license, I'd just use the 0W-20 synthetic oil.
But engineers like me tend to want to mess with everything.

The key is finding out who to talk to by name. Over the years I've done it many times. Another good place to talk to engineers is at international auto shows particularly when new engines are on display. Once they realize you know what you're talking about and have no ulterior motive other than being an enthusiast they usually are more than happy to talk openly about technical matters. There is nothing really secretive in a specified motor oil, it's just a matter of finding someone who truly understands the subject matter.
The point is, the technical info is out there it's just a matter of finding it.

I'd like to know that as well but it looks like no one answered the question although I think it does come with gauges.
Does the engine require the heavier 5W-50 over the standard Mustang GT which is spec'd for 5W-20? For normal fast street use I'd say no. If you're not seeing oil temp's over 230F which the none track spec'd Mustang can generate without triggering the ECU safeties then I'd say the 5W-20 lube would be a better choice not that I'm recommending it during your warranty period.
As others have suggested I'd stick with the Motorcraft 5W-50 partly because it fortunately is very shear prone but that is nothing to be concerned about as OVERKILL has fully explained.
Between now and through the hot Texas summer I'd take the time to become very familiar with the oil pressure and maximum oil temp's characteristics of your engine particularly when you're really hammering it.
With that detailed info' then you can possibly revisit your motor oil choice.
If for example you cannot generate oil temp's over 230F I'd consider tracking down the right engineer at Ford to speak to and request permission to run a lighter oil grade, if not their 5W-20 perhaps their 5W-30? Who knows, you could get lucky and get a proper technical answer.
The ones I've seen don't have oil temp gauges,and the oil pressure gauge is the same one used on all Fords,it just goes straight to the middle and stays there regardless of rpm.

Mine has oil temp built into the info display in the middle of the cluster along with cylinder head temp, voltage, air/fuel ratio.

So they spec a 5w50 that will shear to a 40 weight range..... Definitely run M1 0w40 then.
