Mobil 1 Formulation Updates?

The "solvent dewaxed" product at the bottom? Yeah, that should be Group II/Group II+ I suspect. May be a carrier fluid.

They may not be calling out GTL either now for all I know. We've always been lucky with the MSDS Mobil sheets being as generous with information as they have been, so if they are now starting to hold that back, it just makes them more similar to their peers.

Actually I believe that is group III.

I looked up that cas number and it was group 3. On here there was a listing of common cas's and that one was group 3 I believe.

Unfortunately, that could be said about a lot of content on this site.

Ohh by the way TC... Great job putting this information up on here. Should have said that before now.

Hope you are doing good man.

Solvent Dewaxed are usually Group II.

However, look at the CAS # on the higher percentage product above it, then look at this from Mobil's EHC (Group II+) 110 SDS:

Swear I had seen that possibility being a group 3...

And in one thread on here and of course I can't find it... G man in that thread even asked if this cas number was indeed group 3.

Swear it was in that thread. Or it was possible it could have been group 3.

Not in all circumstances. But some.

Yep, some, I just confirmed.

So, Calumet produces a pile of Group I and II bases under that CAS:

The 600, 325, 150 and 100 are listed under it:

HOWEVER, so is Shell's old XHVI 4.0 and 5.2, which, due to their VI, classify as Group III.

Yeah I thought I was not totally crazy .. or have a CRS moment...

You can analyze oil to death but the real clencher is buried deep in the SAE wear test results. As a Fleet Manager (now retired) I dug thru all this in 2006. Amzoil was the best then for reducing wear followed closly by Mobil 1.
Use a good oil and filter for your application and use a rigorous oil analysis program to determine extended drain intervals, this will save you $$$.
