What does the 5W mean?
It means it is a convoluted, archaic, mis-representation of cold weather performance badly in need of a new labeling method to help oil purchasers make informed decisions.

It is a much improved real-world representation of cranking and pumpability performance that many people on this board disregard in favor of archaic metics that have been shown to be inadequate.It means it is a convoluted, archaic, mis-representation of cold weather performance badly in need of a new labeling method to help oil purchasers make informed decisions.
Me to! Gives me that warm fuzzy feeling knowing i got more paos under the hoodSounds right. The most recent version is, IMHO, an improvement. I like seeing more PAO, but I'm biased, lol.
exactly the same like the Finnish version, read the msds and compere the specs, they do not mach. Also the pour point its not -60. Its -40CCheck the german pds and msds. Its most current. The pds even lists the mrv@-40 which is 21,600 along with the -60 pour point. Msds shows more pao and slightly less gtl i believe

At least Redline says so:
It is close to -60 as shown in this video from the russian oilclub. I dont speak russian and there are many temperature readings in the video. It seems like the actual pour in that video was -54 but i dont speak russian. The msds says <-40 so that would mean -60 is possible.
You should reference the PDS.not any more according to the latest msds

Run a jug of 0W40 FS M1 through Winter. Save the RL to Summer. Though it is too thick.IIRC the VOAs didn't match up with the listed specs. I'll have to look into it again.
I meant the new unused Red Line has to go in somewhere, so I'll just go ahead and use it when I do an oil change soon. Would've rather done it in summer but whatever, it should be fine.
That is something we do not know. Mobil seems to have variations in a few other prducts as well from pds to msds. However the pds shows the accurate pour point for all of the products. M1 extended performance high mileage 0w20 has a pour point of -54 on the pds and the msds the pour point is -18... i can assure you m1 ep hm 0w20 definately does not stop flowing at -18c. Theres a pour point video on youtube of this oil vs amsoil 0w20 which has a pour point of -52 iirc and the mobil 1 poured ever so slightly better at -50c so obviously the pour point they out on the msds is wrong. M1 ep 0w20 has the same pour point as their high mileage flavor but the msds shows -45c...and you are 100% sure that is the updated version? why would msds show -40C if it would be -60? while other M1 products can show for example -45 in their msds![]()
Agree - but the majority of PVL’s spec’d by the OEM’s are 5W or 0W … so it can be a BITOG thing - but betting most folks “follow the fill cap” …It is a much improved real-world representation of cranking and pumpability performance that many people on this board disregard in favor of archaic metics that have been shown to be inadequate.
If I said that it was probably before I got the new battery.I got the sense you weren't 100% onboard with the 5W40 in winter, let alone Red Line. This whole thing started because I thought my car was burning oil. But then in the last 1000 miles or so I found a vacuum leak in the PCV system. I've since fixed that and have been driving hard and monitoring with no change in oil level. So there's that...
RU video is pointless at this point. Dont even know what oil and formula it is. Just speculations. Well time will tell, just like i said above msds dont mach pds. Not even the viscosity at 40C and 100C. Scandinavian M1 dont show any gtl in their msds on the 0w-40. What is right and what is wrong msds is hard to tell right now. Never seen mobil1 mess up this before. Usually they have formula standards on their oils. Maybe a error?That is something we do not know.

Back to the 0w40...the video is 8 months old. Could be a very recent batch who knows. The russian msds shows 30-40% pao and 40-50% gtl. Their pds shows all the same numbers as the us and german ones including the -60 pour point and mrv@-40 of 21,600. All that info has not changed. The viscosity, hths, pour point, flash point, mrv, and density has all remained the same since about 2016 when it switched to the pao/visom. Nothing has changed it appears except they upped pao and lowed gtl slightly presumably due to a shortage as mobil doesnt even produce gtl, they buy it from shell. Mobil changed the msds on alot of their oils this year while the pds specs have all remained unchanged
Good catch on the swedish msds i just checked. No gtl instead looks to be group 3. HmmRU video is pointless at this point. Dont even know what oil and formula it is. Just speculations.

Of course GTL is a Group III base stock (which is subsequently hydrocracked) but I’m assuming the CAS shows it to be not derived from GTL?Good catch on the swedish msds i just checked. No gtl instead looks to be group 3. Hmm
Again i wouldnt worry about the differences in specs on msds and pds. M1 5w30 vanilla has a pour point of -45c on pds or -49f and on msds the pour point is 36c or 97f! Trust the pds for viscosity specs and pour points and flash points vs the sds IMORU video is pointless at this point. Dont even know what oil and formula it is. Just speculations.
