Hi wpod, I haven't yet measured oil temperature. I don't have an oil temperature gauge yet. Only thing I have at this point is an infrared thermometer that I could point at the oil sump. I won't be able to find out until spring.

I've been wondering if the HTHS number is correct. It seems abnormally high for a 20wt.
An older formula of Redline 5W20 had a HT/HS of 3.3.

Would HTHS be a better way to compare these oils, since there is no VII?
Lower group base oils are, for the sake of the discussion, less expensive for HPL (or whomever) to buy on the base oil market. That market priced those oils, and it's lower, which falls in the definition of cheaper.
That is probably a question for the OP.
Cold temperature performance matters to some of us who live in areas where a polar vortex can last for weeks and outdoor temps
So, Pour Point of PCMO 5W-20 "No VII" being higher (-38°F) than the 5W-30 (-76°F) is an automatic fail for me. As others have suggested I would have to stick with the [HPL] Premium Plus variety of the 0W-20 PCMO as the regular Premium PCMO also has poor cold temp performance.
GM used to recommend 5W-30 down to -20F and 0W-30 below that.
I think any oil that passes the SAE J300 for 5W-XX should be fine down to -20F?
Pour point isn't exactly a concern.
It's on the site! I just ordered the euro 10w20. Going to try this in both cars.
The 5w20 uses some GrpIII base oil, whereas the 5w30 is PAO. Besides, pour point is not a valid reference, MRV is. Sometimes when making an overall better oil, the numbers may appear to be “worse”, but remember also there’s no PPDs or VIIs which artificially make other GrpIII oils “appear” better to people focused only on a single aspect of the oil.
I just checked and the 5W-30 PCMO is already sold out.
I don’t believe it was ever available yet It showed sold out from the get go. I am assuming it might just be a day or two.
You’re engine would be starting at a 10F temperature not -30F wind chills do not effect engines.
I know I’m not the only one wondering why you think the wind chill matters to your engine.
If a -10F wind is blowing, your engine will reach equilibrium more rapidly, but it won’t go below -10F.
YOU will feel cold, but your car won’t know the difference.
Wind chill is a measurement of the effect of wind on 98.6F human skin exposed to that wind at a certain temperature.
It has nothing to do with the engine temperature at which you start your car.

Shel,
I checked with my plant manager and the Euro will be available right away. I just learned that one of the materials we need for the PCMO that has been on order was delayed and will come in at the end of the month.
David
Which bitoger got the first order in?
I’ll look into that
Thanks. I was just curious as I've plenty on hand from the August meeting.
Dave said they’re waiting on delivery of a raw material. Then it will be available.
