Then what the heck are you talking about when you speak about back-specing? as that's EXACTLY what Ford did, they back-spec'd engines that were listed for 5w30 and 10w30 for 5w20 when it became available. This includes the first generation of the Modular engines.
I seriously haven't a clue as to what you are talking about here.

THEY CAN'T TELL TWO DIFFERENT STORIES ABOUT THE SAME ENGINE!
Of course they can. Look at the BOSS 302 and Mustang GT, both have 5.0L engines, but the BOSS 302 is "track ready" and spec's 5w50. So does the GT500, Ford GT...etc and these are all Modular engines as well.
You've gotta come up with something better than that.

TRUE, IT'S NOT LISTED OUTSIDE THE US, BUT THE LM GERMAN SITE HAS A US CAR PAGE BUT DOES NOT COPY ANY CHANGES IN RECOMMENDED OIL SPECS WITHOUT SUPPORTING TEST DATA. SO THAT PAGE IS A BETTER ONE TO CHECK FOR A NON CAFE FIGURE.
Which is pretty much what Mobil says: Follow the manufacturer's recommendation, which is 5w20........

WHERE DID YOU GET THE IDEA THAT 0 or 5/30 IS AN EU SPEC OIL, IT's KIND OF COMMON IN THE US.
I didn't say it was. But that seems to be your position, that this engine needs a "long life" Euro spec lubricant because 5w20 is due to CAFE and it shears, whilst the OCI isn't long enough to make one lick of difference here AND the Modular, unless we speak about the GT500, doesn't shear oil! I even showed you my own bloody UOA's as proof of this.

IT'S OBVIOUS TO ANYONE THAT DOES EVEN BASIC RESEARCH AND THE SHORT OCI's GIVE THE GAME AWAY. IF A NEW ENGINE IS DESIGNED TO USE A CHEAP 5/20 IT WILL HAVE A LONG RECOMMENDED OCI, LIKE SOME NEW HYBRIDS.
Right, because the usage profile between a hybrid and a 2-ton van or truck chassis hauling 14K lbs is comparable..... Did you consider the application here? I'm thinking not.
Quote:
NONE OF THE MAIN CAR MANUFACTURERS ARE USING THE BEST OIL, THEY STILL SEEM TO PREFER SHORT OCI's. THE DEALERS FOR THE CHEAPER IMPORTS DO THE SAME THING.
Define the "best oil". They all do extensive testing with their approved lubricants, are you saying these are inadequate for protecting their engines? Because taxi, LEO and Limo folks are going to disagree with you here.
Quote:
CHECK THE PETROLEUM INSTITUTE WEB SITE FOR CURRENT LEGAL CASES. Some of the dealers have been caught in the EU selling the wrong oil, although the last casein the US was the fault of the oil supplier.
How about you cite some examples? I mean you just shot yourself in the foot mentioning the last US example wasn't even an example!
Quote:
I DIDN'T SAY FORD DID IT, IT's JUST A RISK FACTOR AND A REASON FOR NOT ALLOWING SOME DEALERS TO STOCK EXPENSIVE FULL SYNTHETICS. THE ONLY CASES I'VE SEEN ARE PORSCH RELATED AS THEY CHEW UP DINO.
Well, we are in a thread about Ford, and the discussion is about a Ford engine, so if you have no evidence that Ford does it, why mention it?

Replies after each comment, as it's easier not to miss something.
I suggest taking the effort to break it apart using the quote tags when you respond instead of making a big broken mess if you want to go back and forth point-by-point. It makes it a lot easier to read.

If you use a 20 grade think very carefully about using a real top quality 0/20 that stays in grade longer,
my main point is that 20 is OK for some new engines,
We are talking about a brand new engine, that was designed for 5w20.....

BUT not if you use cheap oil or want to to do a longer OCI. The US was starting to get away from short OCI's and cheap oil & filter use, BUT the CAFE bean counters have killed that trend dead by insisting on light oil use.
We are talking about 450 chassis Ford truck. This isn't your grocery getting extended drain on dino or a blend candidate.
Ford uses an oil life monitor with 5w20. Drain intervals are still longer than the "quick lube" changes from years gone by. But usage profile (not surprisingly) is one of the parameters of the OLM and if this truck is being worked as hard as the OP indicates, even if it IS fitted with an OLM, the drain intervals are still going to be relatively short.
CAFE hasn't killed the transition to longer drain intervals in any way. The adoption of OLM's has meant that by and large, longer drain intervals are becoming the norm in North America.
