GrpIII
WalMart - Grp III for sure. They won't pay for PAO. But why do you assume that Grp III is lesser for most motors?

+same comment I have made - I'm fine with the USA accepting GIII as synthetic ... and we commonly have a mix of base oils in several good oils. Many, many, of the long runs were not tied to the most expensive fluids.
This logic helps control VALUE .... and the production company allocations of high end base oils go to more logical lubes that are not dumped often ...
The more demanding vehicles already have plenty of specs to meet ...

I don't like naming names but another member said that there is significant cold (30F and below)start difference. Significant.

-30°F, definitely... +30°F no...

Hmm. I get down to 0F regularly for long runs here in WI.

5w would be plenty fine in that case?

Stay away from that in WI at 0f. Get Mobil1 or something like that.

Why? In order to qualify for the 5W the oil must have a pour point well below 0°; -30° IIRC.

Sure it does. There are bunch of videos on youtube that show Supertech not being able to get out of bottle at all at very low temps (like -30).
Maybe it is just a fluke, maybe does not mean anything, but difference in price is non existent compare to damage. The U.S. has a privilege of having probably cheapest synthetic motor oil in the world. Why not then going with something that you know is really good?
When I was a student eating pasta like 3 times a day, driving Mazda Millenia 2.5 V6 with 260K on clock, I used Mobil1 5W30 EP. I could not afford for my engine to die, so used good oil and FRAM Ultra filter.

Mobil 1 Would Be My Choice Also
How is Grp III "lesser". They each bring something special to the game that the other does not excel at. Actually, my preference is one that is a blend of Grp III and Grp IV. I like to take advantage of the benefits of each.

They do the vids at -40C...don't know why they insist on doing 5W at -40C when there's 0Ws that are designed for it.

Pour point of many 5W's is -45. As far as I know 5W is most prevalent grade.
But again, considering price difference between Wal mart brand and M1 or Castrol, it is really saving money at wrong place. For example a lot of diesel owners with SCR system had issues with Wal mart brand DEF. And DEF is very simple to make.

If anyone is faced with really cold starting temperatures, any one of the M1 0W qualified oils would be the best choice. All have significant PAO content.
There are significant differences in the cold performance of different oils at any given W qualification test temperature.
You may be able to get CCV/MRV numbers from company PDS sheets and you can get these values from any PQIA VOA.
Pour point in itself is of no more than theoretical interest and isn't directly measured in determining the W qualification of an oil.
Finally, I can't understand how anyone who's spent much time here would think that Walmart store brand oil in any grade could be PAO.

I am not sure who in their right mind starts an engine at -40C/F without the foresight to have oil pan warmers installed, even if using a 0w40. Those of us that lived in the interior of Alaska used block heaters, oil pan warmers, and battery warmers religiously. We liked to actually reduce the hardship on our engines as best we could.
once the temp drops significantly below 0°F, my diesel fuel is frozen and I can crank till te cows come home...

-42 while skiing in Southern Alps using 10W40 INA oil (Croatian oil manufacturer). Car: OPEL Vectra B 2.0 16V (Cosworth developed engine). 10sec of camshafts protesting, but after that it was fine. All electronics in the car (bard computer, radio/cd) did not want to start for like 2hrs.
That was not the problem. The problem was that I had to drive downhill on snowy/icy road using lower gears to slow down. Since it was stick, fuel would be cut off completely which means no energy to warm up coolant, which means no heating. It was interesting experience (beside skiing on that temperature, but Slivovitza helped) and actually oil was least of an issue.
