Have mercy ...

They're calling for -34 to -36c for my area tonight. Come Saturday morning it's predicted to be downright balmy at -2c. May have to get out the sandals and shorts!

I just arrived in Hinton 30 minutes ago. It's a balmy -36C. It was down to -40 through Jasper Park.
The 6L 2017 GMC I drove up here in has 5W30 Dexos fast lube whatever.
I'm quite sure I put 5W40 in the 6L pulp mill truck that I use when I'm up here. Neither have block heaters and sit out all night.
I brought some 5W30 Mobil with me to do an oil change.
0W40 M-1 Euro blend is always my 1st choice.
I'll check Cambodian Tire and Wal*Mart for 0Wxx tomorrow.

Ravenol or M1 offer thinner 0w-30 options if that is the objective.


Yes, agree. Since the Burb has 200,000 miles I decided to run a slightly thicker oil, and just get a lower CCS number by going to 0w instead of 5W.

These temps are in Celsius. We usually set the night time temp to 18 then the house temp slowly coasts down to 18 by 2:00 AM. With a -16 temp and strong wind, it hit 18 by 10:30 PM. Going to burn some propane tonight. Calgary has it cold at -34 C.

Ok, I want to hear this:
What 0W has to do with W40? Or what KV100 of LX0W30 has to do with cold flow?

Hi fellows. I can solve this. Here is the PDS for Pennzoil Euro LX 0W30. The CCS Viscosity is 5800 at -35 C which is an excellent cold flowing oil. Even I did not realize this at first.

Those are usually majority PAO base blend - so there you go.

Welcome to the REAL synthetic, high performance arena again.

Me I'm not going outside or driving anywhere if its colder than -15F/-26C

Its going to be -15C in a coupe days in the N.E. USA with another Arctic blast.

And here is the Mobil SDS for 0w30. They didn't say what the CCS Viscosity was. Their MRV Viscosity was a bit lower but what the hey, let's look at pour point. -51 vs -50 for a Pennzoil win.

It's currently -33 F in Edmonton, a city of over a million people. That's a lot of block heaters. laugh

We know the M1's CCS viscosity had to be 6200 cP or less at -35C since it is a 0WXX...even right at 6200 it's less than 7% higher that the LX result.
Based on comments by Shannow, the lower MRV result for the M1 suggests that it has less pour point depressant than the LX unless its CCS viscosity is much lower than 5800. Shannow suggested the the ratio of MRV to CCS viscosity would be 2 for an oil with no PPD.
Multiple discussions on here have established that pour point has little to do with getting a car started in the cold. We see plenty of 5W30s with super low pour points, but they are still 5Ws and will not outperform a 0W in extremely cold conditions.
