Mineral Paraffininc Base Oil - 64742-54-7; VI of +94 to 120, any group.

Mineral Naphthenic Base Oil - 64741-96-4; VI of -15, any group.

Mineral Aromatic Base Oil - 64742-03-7; VI of -185, any group.

Hydrotreated paraffininc, heavy - 64742-52-5
Hydrotreated paraffinic, light - 64742-53-6

PAO's: 68649-12-7, 68037-01-4, 163149-29-9, 151006-63-2, 151006-62-1, 151006-60-9. VII's of +155 or greater.

Diester - 28472-97-1; VII's average +170.

VII Copolymers - 127883-08-3


Additives:

How would one distiguish a Group I oil from a Group II or III?

You can't unless you know the extent of the processing of the oil.

As stated elsewhere, an MSDS does not tell you much about the formulation. An MSDS is primarily for Medical and Environmental purposes.

I understand the point of the MSDS. [Big Grin] But it's also a good tool to get an idea of an oil's content, although not to a great extent. Correct?

The MSDS for Chevron ATF says 80-100% 64742-54-7 Distillates, hydrotreated heavy paraffinic.

Would the term "hydrotreated" be enough to assume this oil was a Group II? Or is this not specific enough.

Far be it from me to disagree with Molakule, but in my early days of "oil mania" when I did extensive research on CAS#s, I determined that 64742-54-7 was in fact the number for hydrocracked/hydrotreated base oils, be they Group II, II+, or III. Solvent extracted/dewaxed oils had a different CAS#. I got this directly off one of the database services listed on the Chemical Abstract Service (CAS) website.

64742-54-7 is a generic CAS number for paraffininc base oils; I don't disagree with you Gman and you may be correct.

The CAS numbers I listed are not all inclusive, but are basic CAS numbers.

Here is what happens: EM, Chevron or Shell or whomever will come out with an oil (hydrotreated, isomerized, etc) and have it CAS registered with a different (new) number.

I.E., New oils produced under a specific process may have new CAS numbers.

If any BITOG members have documented information of new CAS numbers and their Process/Group Types, please feel free to post. BITOG is an informational exchange and educational site.

For example, I recently received a mineral base oil for evaluation that carries 8 CAS numbers for a mix of various Group Oils with many new CAS numbers. Unfortunately, the CAS number is not equated to the specific process type.

BTW,

The designation of Paraffinic, Naphthenic, or Aromatic simply describes the structure of the mineral oil molecule. It has nothing to do with waxes, solvents, or being smelly.

Arrggg

Approximately 75 CAS numbers for mineral base oils , Parraffinic Hydrocarbons "PAO " and various lube Esters would not line up .

I'll try again later
