Do you think synthetic and ordinary modern oil will perform substancially different in cold weather? The article did say synthetic flowed easier, I believe. Do you think the difference is enough to justify the extra cost?

Yes I do.

Ok, you got me, I see your point. The -40F/-40C was pretty dramatic. I've poured ordinary oil at about -10F and it is pretty syrupy, but reasonably liquid yet. The surprise I didn't expect was the near solid paraffin. If it can plug fuel, it can plug sumps. :E
I had to unexpectedly use my diesel last winter, but it was only about 0F out. I wonder how well the Rotella 15W40 flowed? I already had plans for a pan and tank heater and this cinches it.
Thanks for the links.

Ben,
I can't say Consumer Reports is a joke for me but I do take it with a grain of salt, especially regarding new vehicle tests, as you do.
I think the taxi test was legit, one of their better ones the way they honestly qualified it with some limitations. I will say I usually look at CR in the library, when I do, since a subscription wouldn't pay for me.
