By the way, my Buell specs a 20w50, but I use 10w40 mobil 1 4T. Harley specified 20w50 because that is what they sell for all their air cooled v-twins. They don't sell a 10w40, so even though it may very well be the best viscosity for my motor, they don't recommend it because they don't have it.
Just like Harley, I don't believe Ford specs 5w20 because it will do the best job. It is good enough or rather the bare minimum and they can say it get's 18mpg in the city instead of 17.

But with 5W-20, I don't know. How come Ford has back-spec'ed 5W-20 to older cars that were originally speced for 5W-30?
Also, Roush recommends certain engines they build with 5W-20, while others 15W-40, 10W-30, etc? Why would they recommend 5W-20 on motors they build unless it had some benefit?

I have an 1125R by the way, I agree with what you say about Harley specing 20W-50. Harley can't stop screwing Buell in so many ways I sometimes felt.

Also, Ford doesn't sell a 5w40, correct me if I'm wrong, so that's why they spec 5w50 for the track pack gt's, just like Harley spec'd 20w50 for the buells. 5w50 is going to shear to a 40 weight very, very quickly anyway.
It's really not about specifying what oil is best for you motors longevity, but rather what's best for fuel mileage and sales. I doubt Ford even tests oil viscosities that they don't sell. Also the idea that they build a motor around 5w20 oil is just nutz.
5w20 does have some benefits. it flows faster, it makes more power and it gets better gas mileage. It does not offer better protection. I'll be running a 5w40 if I ever get back to the drag strip.

What Roush car spec's 5w20? Any supercharged roush model specs 5w30 at least.

The 5W-20 is speced for their Coyote 5.0L with supercharger, while they go up to 15W-40 at their highest spec.
Have you run 5W-40 in the past? I have a lot of 5W-40 stock for my Bimmer, I wondering if I can use that on the S197?

So, I'm in San Francisco and I went to the Ford.com website and checked out the "Track Package" for the GT. It says it's "Standard Equipment" for the 2013 GT Coupe.
So, do all 2013 GT Coupes come with 5w-50 oil caps and 5w-20 Owner's Manuals? What's really going on?
I also checked Ford.ca, the Canadian site, and they have a "Brembo Brake Racing Package" that has most of what I thought was in the Track package. It has an oil cooler and Boss 302 radiator.
Why don't we start an internet rumor (are there any other kinds any more) that the ones with 5w-50 oil caps have a Boss 302 long block with a regular GT intake manifold. Folks would love that one...

That's what I'm wondering. At the bottom of my last post I included a list of recommended oil specs for their crate motors.
The 5W-20 is speced for their Coyote 5.0L with supercharger, while they go up to 15W-40 at their highest spec.

Are there any European cars that spec a 5w20?
This guy has used 5w40.

They don't sell 5w20 in Mexico or any other countries other than the US as far as I know. The owners manual specs 5w30 in Mexico and South America, probably everywhere they sell mustangs, but here. It's all about saving gas, but people will just drive more and use the same amount of fuel.

I have not used it in the past, but I see no reason why I can't. Surely if the 5.0 track pack can use 5w50, while the non track pack can use 5w20, then I can use a 5w40.

It's freakin hot and humid last I heard with horrendous traffic, I'm really curious what Ford in that country would use.

mabe ford thinks the track pack buyers will be running them at higher RPMS for extended times like on a road course track
Correct me if im wrong, but wouldnt the downside of higher weight oil would be it taking longer to get warmed up?
pros would be the oil staying thicker during extended high rpm conditions.
