So then, why are we even worried?another thing to remember... oil stays up in the cylinder head for a long time...

When India finally went to BS 6 mandating dpf/ scr in diesels, Ford moved their oil recommendation for the Endeavour (aka Ranger with a suv body) from 5w30 a5b5 (wss m2c913 c/d) to 0w20 acea c2 (or the ford equivalent spec rather). Never mind about using a 20 weight oil in 100+ in the shade weather that’s routine in India0w-40 for diesel isn't that common. If you’re not in really cold climate there is 0 need for a 0w. There are plenty of 5w that are readily available. I'm sure Fords Spec sheet for 0w is quite short anyways. Even then with the advancements with cold starting on diesel trucks you could easily get away with using a 15w synthetic.
When I said " I'm sure Fords Spec sheet for 0w is quite short anyways." I'm referring to WSS-M2C171-F1 for their Power Stroke Diesel engines found Here. As you see the 0w-40 oils are slim.When India finally went to BS 6 mandating dpf/ scr in diesels, Ford moved their oil recommendation for the Endeavour (aka Ranger with a suv body) from 5w30 a5b5 (wss m2c913 c/d) to 0w20 acea c2 (or the ford equivalent spec rather).

Moving to a 5w30 c3 or 10w30 / 15w40 ck4 isn’t a bad idea though in this kind of weather
I mean it is perfectly possible to engineer a robust 5w20 or 0wAnything that will stand up to hot weather and towing. Also perfectly possible that there’s a tooth fairy and that the moon is made of green cheese.When I said " I'm sure Fords Spec sheet for 0w is quite short anyways."

But to your point this is not the first time Ford has back spec their oil recommendations. They had 5w-30 on many older vehicles & then said 5w-20 was to be put in going forward. As you stated that hot weather & especially towing in the mix is questionable but did they develop this engine with 20 in mind maybe. I'm sure it gets very hot in parts of India. Thanks for that info!
The engine is the standard L5 duratorq 3.2 liter 5 cylinder diesel that’s ubiquitous for non dpf and then the 2.0 ecoblue but unfortunately with just one rather than twin turbos for dpf modelsWhen I said " I'm sure Fords Spec sheet for 0w is quite short anyways."

Actually what it does is make for for easier cranking and ensures pumpabity down to the guaranteed temperature. It does't protect the wear surfaces better as such, all oils at low temperatures have sufficient MOFT for wear protection as long as it can be pumped.I used Rotella 15w40 in my 93 7.3 International when it was around. I put a cheap (amp appropriate) timer on the outlet that powered the cord of the installed block heater. When it got cold and I wanted the heater to operate, I set the timer to power the heater a couple to a few hours before I started it in the morning. It started perfectly every morning in 3 rotations like it was 40 degrees out even when it was -10. Saved a ton of electricity and was as smooth as silk even with the older Stanadyne Roosa-Master injection pump system. My 2001 Duramax would start in any weather with Rotella 15w40 and the Bosch fuel system and no heater. It was not smooth and was noisy for a while. Was that the best for it? I cant see how it was hind sight. But the reality is the thinner the oil is below zero the better, as it flows quicker thus it protects the wear surfaces better. If we could predict the weather we would be a hero. I have seen -30 In mid New Hampshire region. No joke. As to what oil to use I would guage that on your OCI and factory spec. Take the best advice here and run with it.
I agree however IMO start-up wear = pressure + flow -time. Really the same thing. I really enjoy the project farm videos series on you tube. A few oil related skits shows how slow cold oil flows.Actually what it does is make for for easier cranking and ensures pumpabity down to the guaranteed temperature.

If the oil can be pumped it will flow. Those Project Farm videos are pretty irrelevant in regards to how an engine oiling system works and what actually happens in an engine. You're correct in calling them skits, PF should stick to testing knives and rakes and not motor oil.I agree however IMO start-up wear = pressure + flow -time. Really the same thing.

What I'm trying to say is IMHO, Viscosity matters when sucking and pushing any fluids. Millisecond matter when protecting and lubricating moving parts. Cold starts (when the oil is below X) equate to a high level of an engines wear. I know what you are saying, Positive displacement pumps vs gravity flow don't equate exactly. However they show the flow differences. I agree Project Farm is not a Exact test of anything he does. But repeated results strongly "suggests" strengths and weaknesses of a product (usually not surprising on some because I've found the same results on my own as well) and for this I appreciate him.If the oil can be pumped it will flow.

Yeah I've never seen a 0w40 HDEO on the shelf anywhere here in Texas.Availability is the limiting factor for us in the South. If you are in the northern area where 104-110 isn’t an issue I wouldn’t think it would hurt and could possibly help where it does get below 0. If it gets down into the teens here it only lasts for a couple of days and normally around 32 for lows. We would have to order 0w-40 around here.
Totally understand about the block heater. I have one and I plan on using it.
Your comment about 0W being less shear stable is really what I was trying to get at. Does that mean that over time the 0W-40 oil will start to behave like a 5W or 10W-30? I assume it's not quite that simple...
