Updated M1 FS 0w-40 - More PAO

Go to BITOG home page by clicking “Home” on top of this page, you will find the answer to your question.
 
What is the actual difference between GTL and PAO? Would there be a noticeable difference between the two?
GTL is a Group III product with typically better VI's, available in a rather narrow range of viscosities. It, like other Group III bases, is hydrocracked and contains wax, which means it requires PPD's to achieve acceptable low temperature performance.

PAO contains absolutely no slack wax, so it doesn't require PPD's. It also has slightly better oxidation resistance. But, it is extremely dry and used by itself is hard on seals, so needs to be blended with something like AN's or POE to counteract that. The slate of PAO base oils is massive with a huge range of viscosities.

Found this at my local WallyWorld! This is a different batch number and appears recent.....In New Mexico desert!

Both my jugs old label and new label have the same 4 digit number. Nothings changed i suspect. Not yet anyways
Precisely how "old" is your old bottle according to the date code? The four-digit revision number for M1 FS 0W-40 changed. We don't know when this change happened. It could have happened more than a year ago.

Dated October 29, 2021, revision number 6294:

The difference is the process by which the end products are made. The range of options and relative purities of each are consequences both of the processes themselves, and also the quality of execution of those processes.

Here are some interesting observations. There are two different blending plants—Plant # 102 and Plant # 110—both blending M1 FS 0W-40 Revision # (RN) 6294. Plant # 102 is also adding a serial number or perhaps a batch number to the date/revision stamp. The serial number is absent with Plant 110.

Plant # 102 typically blends Mobil HDEO and TGMO. Plant # 110 typically blends Mobil 1 PCMO.

The date codes we have seen with Revision # 6294 so far go back as far as April 9, 2021. The change to the non-GTL Group III + higher PAO content happened earlier this year if not even earlier.

Here is a label @Krieg sent me with Plant # 110. It looks like they skip the letter I for the month code.
