Something I've been wondering about and maybe some here can answer: Does Ford actually REQUIRE the use of 5w-20 or RECOMMEND the use??
There is the key. They can try and they most likely will. The result will be a protracted legal case which will cost you more $$ and aggravation and time away from work.quote:

Because in some climate and usage conditions it isn't the best choice.quote:

Just for your information the MRV TP-1 for the Conoco/Motorcraft 5W-20 oil is 18,000cP@-35*C. Not the 60,000cP@-35*C you said. Mobil 1 5W-30 is 12,700cP@-35*C. So Motorcraft 5W-20 is not that "bad" even when compared to a full PAO synthetic for cold weather starts. Of course a 0W-20/30 true syntetic will pump better in really cold situations. But for the price difference if you don't have those really cold temps the Motorcraft 5W-20 oil is good, especially if you do a lot of short trips and won't want to leave the oil in too long over the winter. It doesn't cost a lot to change and you get fresh oil for the spring or midwinter oil change.quote:

I asked Bob that very same question last summer and his exact words were "very unlikely"quote:

The Motorcraft oil is a blend, so it still flows ok at colder temps. Otherwise, it would not have an MRV below 20,000 cP at -35 C.quote:

I just looked at the Pennzoil site and they said that the multigrade "dino" Pennzoil meets the Ford spec's for 5W-20. And the UOA we've seen for this oil have been really good. They are cheating themselves out of customer's if they don't put on the bottle that it meet's Ford's specs. I thought I read on this site that it's a blend of Group II+ and Group III. They just don't advertise it as a blend. Similar to Motorcraft calling their 5W-20 a blend and yet Conoco who makes their oil and is the same does not call their 5W-20 a blend.quote:

Ford and Honda spec 5W-20 oils then it would not make sense for an oil company to make a 5W-20 that could not meet Ford's tougher specs
Castrol GTX 5W-20 dino does call out the Ford spec on the bottle. Maybe it is really a blend.
