FWIW - I have a good friend who's a chemist, but not familiar with oil formulations. I mentioned this thread to him and the first thing he asked was "Are they using it ( alkylated naphthalene ) as a surfactant?"quote:

Mobil Supersyn uses the AN's and they are for sale to other blenders but who uses them currently ? Not a clue .
Typically, one would obtain a 1 to 5-gal. sample along a "Certificate of Analysis" (COA) which would show most of the details.quote:
The kind of people who would consider buying this product would be obtaining samples, pricing, and technical data such as production variability and additive compatibility, so they wouldn't be relying on the specs on the website for decision-making.
I'm wondering the same thing or even if its in the M1 SS. Sounds like a very impressive base. Aren't ya glad I posted it?quote:
Are you guys using this groovy base oil in the Mobil Synthetic Blend and if so , does it help clean ?
But with his background he might could help us along ? He already knew something about it .quote:

Apparently they are not pushing this as a base stock but a blend stock, and in that use - a fully formulated motor oil - an AO would usually be incorporated.
I'm with you. I'm going to try to get him to reg. He works with solid rocket fuels plus coatings and adhesives but knows plenty about a variety of things chemical. He's the one of the guys that first convinced me to try Mobil 1 in fact. I'll see what I can do...quote:

I only found 5 hits when searching through all the forums for AN's. Sounds like they are very valuable to a formulator and I wouldn't be surprised if a small amount is present in M1 SS. The M1 descriptions lists Mobil 1 as being Synthetic base fluids including Pao. So could be esters but I'd be willing to bet it's AN. Could this be the "ester less" part of M1? Are these AN's even really classified as Esters? Maybe George Morrison knows.quote:
That would be a good topic since Alkylated Naphthalenes and benzenes are set to possibly replace expensive esters. More testing will show if they will really do this.

It sounds like it would suit this application perfectly.
Rick.
Not quite correct, Mobil's AN is an olefinic AN and the additive solubility for the higher viscosity AN is pretty poor as of now. They only have two major AN's for PCMO's.quote:
[Comment from Geoff William: The first component (alkylated naphthalene) has the advantage over PAO and esters in that it has the best additive solubility and the best seal compatibility of the 5 most common engine lubricants (PAO, esters (2 types) and mineral oil)."
Group V fluids are esters, AN's, AB's, etc. Anything not conforming to Group I-IV are placed in the Group V category.quote:

So PAO has it's own group. I would guess that someday (if things get too crowded in the V group) they will have to split out a Group VI, leaving esters with it's own group.quote:
