May not be scientific, but hey,,always an eye opener,,move to Ga,Tn, or somewhere down south...In Tn, we usually do not see -40F,lol. enjoy

The simple test does make one think, maybe Mobile 1 has something here....I use Mobil Super 5000 5w30 and not problems,,yes good ole dino stuff...Tennessee

Believe it or not, I looked at this video today morning before you posted

doesnt matter to me - I'm not heading out at -40 - that's killer cold. Kill the car or you if you break down. -17 F is my limit.`

How well is the good pouring oil when the engine is HOT? Just ho hum?

Also odd to me that they picked M1 HM, although that is not as egregious as comparing ST dino to a bunch of synths.

That said, this somewhat silly video did get me to start wondering about the jug of 5W30 RP I had purchased just before seeing it the first time. I started poking around more and found the PQIA table of 5W30 synths, only to see that RP had one of the highest CCS viscosities, middling NOACK performance, and no moly or boron. I ended up taking it back to WalMart and getting M1...found out later that RP also more calcium than I would like to have in my DIT engine. Don't mean to bash RP, just don't think it's the right oil for me...

I noticed that,,,yes, they should have use supertech, synthetic,,to make it fair.
 
I heard on the radio this morning the coldest temperature measured today was somewhere in Russia,-80F. Now THAT is cold!!
 
Yep been discussed before not very scientific because they didn't use the same sized opening on the bottle and they tested the oils below what temperature they are supposed to be tested at.

It would be interesting to see how other Mobil 1 oils poured compared to the HM. The standard 5w30 and Extended Performance 5w30. The difference might not be that noticeable visually, but, on the back of the Mobil 1 oil bottles I have on the shelf, it has that chart showing the different protection levels and different conditions and how the oils perform in those conditions. One of those is "Low temperature start-ups" The number of check marks indicate the relative performance. What I thought was interesting is that the high mileage Mobil 1 has one check mark. The regular Mobil 1 is two check marks. The Extended Performance and Advanced Fuel Economy have three marks.

Since Mobil uses "•Higher base oil viscosity to help reduce leaks and provide better high-temperature protection" in the high mileage Mobil 1, I wonder if that come at a trade-off with low temperature flow and pump ability.

According to the Russian Oil Club, the CCS viscosity of M1 5W30 EP at -30C was a little lower than that of standard M1...I can't look at that website right now to get their exact number, though. I've never seen a VOA for the HM 5W30 (haven't looked, either), but I would expect that it would be thicker than the other two at extreme cold. The ROC also pegs the M1 5W30 ESP as being thicker than regular M1 at -30C, think it was something like 5000 vs. 4000 cP.

I am running the 5W30 EP right now and am shocked to say that I actually find it a bit noisy...I thought all that stuff about loud oil was a myth, but I have been hearing stuff here and there that I'm pretty sure I would have noticed before. The EP does have a lower HTHS than the standard 5W30, 3.0 compared to 3.1....????

It's kinda like Bigfoot or UFOs. It's just a myth until you see/hear it for yourself.

-40 is kind of easy to work with, as you can do it in So Cal with dry ice.
25 years or so ago I did a similar test with what was then Mobil-1, in a pan.
You don't see much wax crystallize, compared to a conventional oil, and the crystals
seem to be what really cause viscosity to rise.

I'm sure it's been beaten to death, but here goes.

A truly scientific test would be to place all samples in identical test tubes with identical volumes of oil.

All the tubes would be refrigerated overnight to get them to the test temperature.

Place all the tubes in a rig that would allow the experimenter to begin pouring simultaneously.

Time how long it takes to pour a fixed volume of each oil under test.
 
I saw this video and it's so dumb. I don't think -40F is really anything many people see. Most of those people live up in Alaska and leave their cars either running or plugged in all the time.

I wish they could do a test at like -15 30 and 50 degrees or something like that.

Yes. Pour point testing is problematic enough as it is, without simply grabbing the bottles off the shelf, getting them cold, and turning the things upside down while holding a stopwatch.

motor_oil_madman: How rare it is depends upon where one lives. But, that being said, I don't choose oils by pour points. I use the number before the "w" in the SAE grade. I've seen 15w40 examples, actually was Royal Purple's CI-4+, with a pour point around -45 C. That doesn't mean I'm going to use it at that temperature, since that temperature is well outside the MRV requirements for the grade.
