TWBG, M1 is using Group III+, AN, PAO and POE in M1. A very good blend of base oils.




I haven't seen any evidence Exxon-Mobil is using Group III+ instead of Group III. Further, what evidence we do have, it's mostly Group III and AN, with very little PAO or POE.

Here's one MSDS that shows three grades of Shell XHVI:

And there's more CAS numbers to be had there:

For anyone who says a switch from PAO to Group III is fine, here's some Shell info that all Group III base stocks are not the same.


"It is true that ROTELLA T Synthetic is Group III (not PAO) based, but you must keep in mind that not all Group III base oils are created equal. ROTELLA T Synthetic is made with Shell's XHVI base oil, which unlike other Group IIIs does not begin as distilled crude oil, hence of all Group III base oils, XHVI is truly the only one that can legitimately be called "synthetic." XHVI is a wax isomerate, meaning that it is made from the slack wax removed from distilled crude in normal solvent dewaxing. This slack wax is catalytically transformed (isomerized) and hydrofinished into a chemically pure base oil which rivals PAO in virtually every category. There are other "synthetic" oils out there based on Group III, but Shell's is unique in that it uses XHVI base oil. Chevron and Petro-Canada produce Group III base oils that come close to XHVI, but even though these oils are all hydroprocessed and utilize the same type of isomerization technology employed in the making of XHVI, they are not the same thing. Only XHVI is made from pure petroleum slack wax and its CAS number is 92026-09-4. The CAS number for the more typical all-hydroprocessed Group III base oils is 64742-54-7. If you want to know what your "synthetic" oil is made from, take a look at the MSDS and look for these numbers. (The CAS number for PAO is 68037-01-4)."

I think I posted this on the Rotella forum about four years ago, so it isn't "from Shell," though I got an e-mail from Peter Van Benthuysen at the time confirming the accuracy of what I wrote.




I wonder how many long time members actually remember that your original username on here was XHVI?

Yup. I think my very first post on here was about Rotella T Synthetic and XHVI base oil.

I still post on the Rotella forum as as "XHVI." I also posed as BillXHVI a few times over there because I forgot my password for my XHVI user name.
 
427 read my PM. It DOES contain Group III+, AN, PAO and POE.

Wonder what oil Jean put in his limos? Maybe that famous choking incident was on a guy trying too hard to get him to switch brands.

Can't. I automatically delete all your PMs.

As far as M1 containing Group III+, I'm sure Tom will tell you that he only assumed M1 contained Group III+, he doesn't know for a fact if it does or doesn't. It could just as easily be any of the Group IIIs out on the market.

One other point...weren't you the one who violently exclaimed in another thread that it's the final performance of the formulation that matters, not the basestocks? If that's the case, what makes this blend of basetocks any better than any other?

It is the performance of the oil that matters. But isn't performance basically determined by the basestocks and additives?

Some company may be slightly better than another at the perfect mix of basestocks and additives...but I bet the overall quality of the oil, and its level of performance, reflects the quality of the basestocks and additives.

Shell seems to on a roll right now. Shell / Pennzoil/ Quaker State offer good performance and they price their products fairly.

Amsoil and Redline offer higher levels of performance and address specific needs...and the additional price increase matches the quality increase.

Mobil 1 [ except for TDT/ Delvac1 and 0W-20 ] and non GC Castro Syntec are the two oils that seem overpriced.
 
Alight, this may actually be my first post, but I have been reading on here for quite some time on and off. I just have one question, could someone direct me to any links or provide any information, as to what people are saying here about Mobil 1. I have used this product for many of many years, but I am always open to spending my money on something that is better. This may be an old topic for many on here, but to me, I am interested in knowing some of the facts. thanks in advance.

Blue, here are a few *recent* threads to get you started. But use the search feature, look for threads with "Mobil 1" in the title, go back about about 4 months, and you'll have more reading than you can handle.
