compared to motorcraft oil,do all 5w20 oils like penn,havoline,gtx,valvoline meet the ford spects?
5w20 oil, are they all the same?

Ford specs are harder to meet than gf-4. Longer duration, I believe 240 hours versus 168 hours on the oil breakdown scale.
5w20 Motorcraft oil is a semi-synthetic. Petroleum oil may meet Ford specifications but only a semi-synthetic oil meets Motorcraft specifications.
I don't believe that's true anymore under GF-4. However, Ford's WSS-M2C930-A/WSS-M2C929-A spec does have different limts in a few key areas, and, the oil composition/properties and test results have to be registered with Ford. If an oil meets either of these two specs, you are somewhat more assured of decent quality.
This doesn't make any sense whatsoever.
I tried to decipher that statement as well, 427.
As for the intent of the original question, the jury is still out. But the question is muddled as well.
Nobody speaka da engrish anymore?
I'd like to think the Amsoil, Redline, Mobil XW-20 offerings are a tad better - but this doesn't seem to fit your question and the data is not fully in. Amsoil 5W-20 XL (Group III) seems to do excellent. UOA in my Honda V6 sometime.....waiting on OLM (60% currently)

You'll see this from time to time. A dogmatic poster that never quite interacts. They appear to realign their dispositions, off line, based on the reactions/objections to the presented material ..but just continue to give dogmatic dictation. Eventually the technique is refined enough to get fewer objections. The poster then tends to think that others have finally seen the light.

I imagine that Coke meets Coke's specifications and Sprite meets Sprite's specifications where as both meets the specifications of the Coca-Cola company. Is this scenerio similar to the Motorcraft/Ford spec comment above?
What did Gary just write?
IF Motorcraft has different specs than Ford, it could make sense. That's a bigga IF.

It would be odd. Ford had MC 5w-20 made to create the supply for their spec'd oil. There would be no mass availability of 5w-20 without Ford's spec and the production of the MC product. MC may have taken the easiest way to achieve the spec's with whatever constitutes a semi-synth. I don't think that we know what constitutes a semi-synth, do we? Isn't that a nebulous definition?
Wow, this is getting confusing. I found this page on the Ford web site. From the page:
Is it really possible that Ford and Motorcraft specs could be different? They seem to me to be almost the same company with simply different branding.
Yep Bryan K - that is my understanding.
20 W oils were subjected to much greater testing lengths than other oils, primarily because of Ford's stringent requirements.
Now, compared to before, it's a little easier for he 20s, and tougher for the rest.
Oils are tested the same now - a little less for the 20s, and more for the rest.
The bottom line is that 20s always were very good, and still are.

I don't think that's what was being said (although what was said may be flawed). What I read is that Ford's spec's are Ford's spec's ...all meet them. They are "performance spec's" as opposed to something like +4 ATF which is also a formula/material spec. So, even though MC 5w-20 chose to meet Ford's spec with Semi Synthetic, it may not be the only way to achieve Ford's performance spec's.
That doesn't mean that the statement has any truth to it. All 5w-20's may need to be Semi Synthetics to achieve the spec ..they may just not, due to % of content, bother with the Semi Synthetic designation.
This is a question:
Aside from MC ..are there any other semisynth 5w-20 oils? PZ doesn't list a Semi Synthetic in a 5w-20 weight on their site. Nor have I seen any at WM. All refiners typically offer dino, semi, HM, Synth. The 5w-20 (non-full synth) oils, outside of MC appear to be isolated by themselves.
Dude, you haven't a clue.
Ford has two current specs that closely parallel GF-4 requirements, WSS-M2C930-A for the 5w20 grade and WSS-M2C929-A for the 5w30 grade. Both grades can be made with a either Grp II+ alone, or a combination of Grp I thru Grp III and meet their respective spec which are identical except for grade. GF-4 10w30 is the lone stepchild that can be made with primarily Grp I+ and Ford doesn't have as strict a spec for this grade.
To answer the original topic/question, the lower cost dino and dino+syth blends of 5w20 that meet Ford spec WSS-M2C930-A of are roughly the same quality. Something like Amsoil 5W-20 XL (Group III) and Mobil 1 5w20 are premium "synthetic" products that probably far exceed the WSS-M2C930-A requirements.

The Ford Engineering Material Specification for
SAE 5W-20 service fill oil is WSS-M2C930-A, which specifies primarily ILSAC GF-4 requirements. In
addition, VG follower pin and ring wear limits and the 30 mg TEOST limit are specified.

I would suspect that there are others out on the market also.

What. Like Mobil Clean 7500 5W20?

Hey, pal. I asked the question. Are you giving an answer (insert De Niro, "You talkin' to me?")?
