What is the "SuperSyn" in the new Mobil?

I don't know if this was hashed out here yet.I just did my summertime oil change.My 4.0L Jeep engine uses 5.7 litres in the sump...so I put in 4 litres of 10W-30 and 1.7 liters of 15W-50 Mobil oil with SuperSyn..what ever that is...what viscosity I have who knows..11W-38 sounds good to me [Big Grin] ...anywho...what is the SuperSyn additive in the new Mobil oil...their web page says the 15W-50 has a little extra SuperSyn than the other grades..by the way my idle oil pressure in drive (hot) is up a tad...and the notorious piston slap with these motors is almost non-existant now [Happy]

I just asked the same question the other day. G-ManII had a good answer:

I've noticed that description before. Here's my take on it: ExxonMobil's SuperSyn PAO is a very high vis PAO and is used in some measure in all grades of Mobil 1. MORE of it can be used in the 15w50 than in the other lighter grades.
I have noticed thought that M1 15w-50 has more zinc and phosphorus. Could this be it? [ May 16, 2003, 09:43 PM: Message edited by: buster ]

Mobil has marketed for some time a proprietary high viscosity and high VI PAO called "SuperSyn." The new formulation of Mobil 1 utilizes some of this PAO, as well as new esters, and new additives. Hence, the totality of the package is what makes Mobil 1 "SuperSyn," even though the name itself comes from the proprietary PAO.

I believe that is the additive. Just like Royal Purple uses Synerlec®. I have notice this additive causes Royal Purple to cling to surfaces, so the film is a lot thicker than normal. I'd say 40wt Royal Purple is equal to 50wt dino oil in film thickness. The FM in it is very slick. I can feel the difference as soon as I changed my dino 15w40 Delo 400 oil with 15w40 Royal Purple. Also I noticed when I changed my filter the first time with it, it didn't drain out of the passages leading to the filter. Must be that film strength. I'd say it's like adding Lucas oil additive to increase oil's film strength. The oil just sticks to my dipstick every time I do an oil check. So far I have 3500 miles on it with road racing, drag racing, and the oil is barely light brown. By this time the Delo 400 was very dark brown. Leo

Somewhat analagous in some respects to Mobil's SuperSyn combo is Schaeffer's Supreme, which contains PAO's, a surfactant (surface active agent), also an FM, and a special mix of AW and EP additives composed of ZDDP, MoTDC and organic Antimony compounds.

What about the Penetro in Schaeffer oil? Is that simply their name for the combination of additives, or is it a seperate secret ingredient? I always thought Penetro sounded like the name of some superhero porn star! [Big Grin] [ May 17, 2003, 05:05 AM: Message edited by: Patman ]

It is ECLA, a special Alkylamine: primarily a surface-active agent (surfactant) which causes spreading of the AW additives. Being multifunctional, it is also a corrosion inhibitor, a lubricant, and a dispersant. I can't recall if it's in an ester format or not. Will do some searching through my DB.

Me too, Patman. Can't you hear the TV blaring on Saturday morning: "Marvel Comics Presents the new SuperHero pornstar, PENETRO." I wish Schaeffer's would go into a room, close the door, and think up some new names for this additive mix. The additive 'penetro' is the mix of moly, antimony, and the very slick surfactant, which also acts as an antioxidant and synthetic lubricant. You can get this additive via #132. It is worth it for the antimony additive alone. [ May 17, 2003, 12:09 PM: Message edited by: MolaKule ]

What is "the very slick surfactant" you mentioned? Some sort of ester?

You know, instead of you guys guessing, you could just go to mobil.com and look it up. It's NOT an additive. SuperSyn is a very, very, very high viscosity PAO oil. It's so high, it falls right off the SAE xW-xx chart. Anyway, this ultra high viscosity SuperSyn is mixed with other PAOs and esters to make the final Mobil 1 product.

SuperSyn PAO comes in various viscosities; it's not just one "very, very high viscosity." And even though Mobil "borrowed" the name they had already trademarked for their proprietary PAO, it is the TOTALITY of the base oil blend and additives that makes Mobil 1 SuperSyn in distinction from previous formulations.

As GMAN stated, the new bottles of regular Mobil 1 state new wording on the back of the bottle. It states "contains SuperSyn, a high viscosity synthetic fluid". So it's clear that around the 2004 time frame, Mobil switched to predominately Group III and is adding SuperSyn high VI PAO to the mix along with AN's. Nothing special about it. The move to Boron esters and phosphorylated borons along with high levels of Ca are not that unique these days although they were ahead of Amsoil with the Mg/ZDDP for quite some time. (API SM)
