Also according to this site (bold text my emphasis):
http://www.swedishbricks.net/700900FAQ/Fuel-LubricantData1.html

"True synthetics are generally Group IV (PAO) mixed with Group V (Ester) base stocks, like Mobil 1, Valvoline Syn Power, and Amsoil. Mobil began using straight PAO, but switched to a very good blend of the two. Their additive package seems to be among the best. [Email from Mobil Products: 1. Mobil 1 Tri-Synthetic is a blend of alkylated naphthalene (Group V), PAO (Group IV) and ester (Group V). The alkylated naphthalene is for improved deposit control. The Mobil 1 Tri-Synthetic Formula 15W-50 is A3/B3-B4-98 approved. Mobil Delvac 1 is B4-98, E5-99, SJ and CH-4 approved. Mobil Delvac 1 is a proprietary blend of synthetic base stocks formulated for optimal performance in diesel and gasoline engines.] [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)."

Maybe it was said above but I wonder if there is a CAS number for the alkylated naphthalene?

If you ever run across the CAS number for it please post since Mobil has this fluid for sale to blend into mineral groups also I'd like to know what oils will be using it .

Just the curious type .

I wonder if the GF-4 Drive Clean uses it ?

Not sure this is quite what you are looking for, but..

Product: Alkylated Naphthalene Sulfonate
CAS Number: 146239-96-5

I don't know how the alkylated napthalene would work with the IV+ polyalphaolefin which Exxon Mobil will be bringing into the market in mid-2005 when the Beaumont plant comes on-line.

Thought I'd bump this up after reading from Mickey _ M that Mobil will be producing these come next year. Does anyone have a guess or idea of how these AN's will perform and if they are already being used in Mobil 1 SuperSyn?

I think the used oil analysis are telling how the AN's are working out

buster · Sep 28, 2004

You could be right bc if I remember right, George Morrison said the basestock used for Mobil 1 SuperSyn doesn't get sold to anyone else. Maybe George was referring to this part of the oil.

MolaKule · Sep 28, 2004

Mobil will sell anyone ANY of their base oil products if you have the Mula and can handle a minimum of 55 Gal. drums.

I believe they are still testing AN formulations.

Thanks. I guess we'll know in time.

M1 could be already using them a bit. Their oils stay in grade really well.

How do you know that AN's help an oil stay in grade?

Better thermal and oxidated stability than mineral oil, PAO, diesters, alkyl benzene

Pure guess.

I was just throwing around the idea. I looked at the PDS of AN's and I found the above.

buster · Dec 2, 2004

Bump...

I wonder if this along with more Boron is what gave Mobil 1 the recent color change? When I sent them an email about it, they did tell me that it was improved for better oxidation and deposit control. 2 things AN's help.

I have 2 questions based on the above quotes.
1) Which grades of Valvoline Synpower (if any) are Gr.IV,Gr.V mixes. (I thought SP was a GR.III)
2) If Mobil 1 Tri-Syn was a blend of AN,PAO and esters then how was it improved when they went to SS.

Not sure Tri-synthetic was using AN's.

It did. AN was one of the three synthetic fluids in the "Tri-Synthetic" formula.

buster · Dec 4, 2004

Ok thanks. Couldn't remember. Well then Mobil 1 is now using the new PAO/Additive system which is what SS is. No one knows if they are using the AN but M1 is Esterless from the discussions we've had on here. Not sure if the AN replaces the Ester or not.

The leaflet with New Supersyn in UK- 3 synths, so PAO,AN and ?

They specify AN in the leaflet?

I found the answer to ques #2 using the search feature. The SS has moly while the Tri-Syn apparently did not. Thanks.

If people would like to see a white-paper on AN's, I'll be glad to post something in the Interesting Articles section of "Science and Technology of Lubricating Oils and Additives."

Molakule,
I have searched so if you have written such a paper I apologize. I would like to learn more about AN's .

The pro-s and cons. I take it is not your favorite subject matter since I take it you think esters serve the function better but it seems that AN's may be a reality in many formulations so I look forward to any writings you have on the matter.

buster · Apr 30, 2005

If what XOM says is true, then AN's are better then esters in some aspects. They refer to diesters though and not Polyolesters. Have no idea if this is true. They might be cheaper which could be why. Mobil 1 SuperSyn uses PAO and AN's and no esters.
