Fresh off the Press! The spectrographic oil analysis results for the Mobil 1R vs. current formulation Mobil 1..

Viscosity, 1R = 10.5
viscosity, 1 = 10.2

Calcium, 1R = 2856 3% greater than M1
Calcium, 1 = 2773

Phosphorous M1R = 1912 82% higher than M!
Phosphorous M1 = 1049

Zinc M1R = 2105 87% higher than M1
Zinc M1 = 1127

Moly M1R = 108
Moly M1 = 100

Viscosity Index 175 for Mobil 1 R

Thus the new Mobil 1R has signifcantly higher treat rates than regular Mobil 1. Of course there are many aspects of the oil that spectro cannot uncover, even in the additives shown with respect to exact chemistries, qualities, etc.. Moreover, it is going in my Sequoia tonight; will follow on with oil analysis trending to see how it fares in a regular engine.. Should be interesting..

Both oils tested at the same lab (www.avlube.com), same day...

Wow talk about ZDDP! George, are the base stocks similar though? It looks like a highly additized Mobil 1 oil. For $2qt more, I suspect that is the additives making up the difference in cost.

Also TBN, Boron etc??

Wow! Thanks for that...

Thats the highest about of ZDDP Ive seen in almost any oil. But whats with the Moly? I guess they're only using it solely as a FM, not a AW agent.

Also the 30wt isnt exactly as thick as I hoped it would be.

The API would choke on themselves if they saw this! Haha
 
Looks like Torco......

If you tested this at Blackstone I bet you would see about 1600-1700 Zn and P.

That's still the highest I recall seeing by about 400ppm.
 
I don't think a spectro analysis will tell you the amount of esters either correct? I'd like to know the Boron levels.
 
Thanks George. Definately not an SL econobox oil, but again, this is for (I assume) high output engines and racing applications.

And no doubt, lots of little hidden goodies we can't spectro.
 
Buster, that is correct; the spectrographic analysis tells us nothing about the base stock.. As I mentioned before, the engineer I spoke with who worked in developing this oil over the past several years for use with Penske racing indicated that the base stock was indeed 'trick' and utilized a chemistry that had been developed a few years ago but was not used as the product folded. As it turned out that oddball PAO chemistry performed incredibly well in the race car engine, providing wear minimization levels that were unequalled with previous formulations along with significant energy reductions/savings. However, I have not seen anything in writing about the oil since that discussion a year ago..
Moreover, the Mobil 1R is now in my Sequoia. I will post my follow on oil analysis results which we can trend... I am most anxious to learn what others find when they change to Mobil 1R....

The viscosity is disappointing. I'd like to know what the HT/HS number is for this oil. Wonder if it could meet the >3.5 requirement for A3?

This sounds like almost the exact same language that Mobil used in their press releases for SuperSyn.

I was thinking the same thing. Mobil's press release specifically mentioned shear stability as a key componen to this oil. I would think that it has to be shear stable to be used in a NASCAR engine. This is where the PAO might be different.

Whats Ironic about this is how in the news story the Mobil rep said whether it's used in a Honda Civic or Grand Prix, people will notice how much longer their engines last. If any oil would be a concern to a CAT, it's this one. I wonder what the NOAK is as well?

What is wrong with the 10.5 vis? What am I missing here?? My Sequoia is perfectly happy with this vis, as is my C-5 Corvette, etc. etc.. Please explain.....

I think many people (myself included) want an A3-rated (HT/HS vis > 3.5 cP), 30-weight oil; in most cases this usually means a ~12 cSt kinematic viscosity.

Nothing is really wrong with it, provided the oil can maintain this vis over a 7500 mile OCI. I still don't see how it can have a HT/HS vis of >3.5 at this viscosity, though.

I'm just surprised that a "racing" 0w30 would have the same vis as the "street" Mobil 1 0w30. I would expect it to be in the 12.0 range like the Castrol SLX 0w30.
 
The viscosity is certainly one of the attractive aspects in terms of efficiency.. If an engine is optimized for a 30W and one has a 30W which maintains that viscosity very, very well, any increase in vis is going to do nothing but rob horsepower, create heat, reduce efficiency... And then one with a trick base stock, super endowed with additization...... My Sequoia is quite happy tonight.....

The newest Quaker State Full Synthetic 5W30 oil (which is a group 3, per Quaker State tech rep), meets the A3 specs, and is 10.5 and @40C cSt is 56.8 .

Good Day,
Steven

George, just like any other oil we discuss here, this oil is going to have to prove itself with UOAs. Until then, all this talk about "trick base stock" and "super endowed with additization" is just marketing BS, plain and simple. As for your Sequoia being quite happy, well, how do you know that without a few thousand miles and a UOA?
