Very interesting! I didn't know that! Hmm...

Hey Folks, this is a racing oil, it's not designed to go for 7500 miles. Also no race team wants a high viscosity. They want the lowest possible viscosity combined with the ability to keep metal parts separated for a maximum of 500 to 1000 miles.
If the oil was a 15wt and could keep the metal parts apart for the 500-1000 miles they run thats what would be in the engines and it could very well be what they are currently running.

For comparison heres a actual post race UOA of a popular NASCAR Chevy after running (winning) a 500 mile race. Brand is tricked union 76 syn ?w-30, 4 years ago.
Lead 800
boron 80
sodium 200
Magnesium 1450
calcium 7400
phos 1000
zinc 1000
titanium 50
vis 10 cSt
TBN 24
Thats as much as I can share.
I want to see more of the "NASCAR" formula M1.

Sounds more like the paper I read last year which indicated that Mobil had developed a series of PAO's blends of varying viscosites that were more shear stable, and the addition of the newly developed TME ester that increased oxidation stability and friction reduction.
No flame intended on anyone, but I don't remember the GC stuff getting this beating when it first came out. Many have speculated it's ester based which HAS NOT been proven as of this moment. It's good to be skeptical, but I think we are being a bit unfair with this M1 R.
Personally, I think I'm more interested in the 5W-40 SUV&Truck oil. M1 R seems a bit expensive, considering there is Redline and other very good oils for a bit less. I might change my mind in the future, depending on how it does.

Will the 'real' SuperSyn please step forward. What was the prior SuperSyn? A beta program for the new oil? Mobil must think we all have short term memory problems by using the same words.
Technically the engine may last at long time. The CAT- well that is field replaceable.
I totally agree with speedybenz. This is a racing oil and is designed for race cars. Just because it is a racing oil doesn't mean it is good as a PCMO. A race car will use a lower viscosity to reduce hydrdonamic drag inside the engine, yet still provide enough anti wear protection to finish the race. A race car engine will not be around long enough to develope sludge and extended drain intervals is not a factor either. So I wouldn't run out and purchase the stuff for your passenger cars just because it's new or it says racing on the bottle.

I will give this oil a try for 3,000 miles. I have a 2003 SAAB 9-3 with a 2.0T. It has a high pressure Mitsubishi TD04 turbo. SAAB uses Mobil 1 0W-30 Long Life for factory fill. It sells this oil and uses it for their no-cost maintenance visits also.
I already changed the oil out at 3,000 with the LL stuff. I will be doing a UOA on it. I will do the same for the R. I know the SAAB turbo oil has a very high TBN count. I would like to see what the TBN will be on the R.

Tri-Synthetic(TM) At least the naming isn't as confusing (to me) as the various Intel(R) Pentium(TM) processors

Thanks for sharing this lab report, George. I hope Mobil 1 publishes full specs for this oil soon.

How true!

George do you have more data from this VOA that you could share with us, such as magnesium, TBN, boron, etc?
I would not be concerned at all about it not meeting the A3 spec. I believe that this oil will with it's advanced PAO and on top of it, they do specify "outstanding" shear stablility. Mobil 1 0w-20 is only a 8.8cSt oil and shows outstanding UOA's. I expect similar results with this, hopefully. Patman, George said all TBN's are high on most oils so he didn't test it. We will see it eventually I guess.
The more I look at this, the more I'm becoming convicned that this Mobil 1 Racing oil is nothing more than 0w30 SuperSyn with more ZDDP added to it. If this were a true "racing only" oil, the calcium detergent wouldn't need to be at SL levels, which it clearly is in this oil. Couple that with what George said the engineer said about the origin of the base oil used (which is almost verbatim what Mobil claims is the origin of the "SuperSyn formula"), and it's totally logical to conclude that this is nothing more than SuperSyn 0w30 that has been doctored up with more ZDDP.
GMann-II, it is a doctored up M1 SS. Racing oils dont have detergents. They could have chosen a thicker base stock, but for HP gains, a 10.5cSt oil is more beneficial. Although for $2qt more, I think it is just more additization. I guess the only way to tell if the PAO is better is if the HT/HS number is greater.

I agree.
Would I trust this in my car at the track this summer? Yes.
Do I believe that this will be good for extended drains and have a low Noack? Not yet.
I'm trying to sit tight and wait for official Mobil specs and UOAs, but I may give this oil a shot in the spring anyway (depending on availability). It will be Mobil's last chance before I go Amsoil. I'm interested to see how this will compare against their 5w30s and the s2k.
I think this oil will be capable of long drains. First, it most likely will have a high TBN. It has enough ZDDP for extended drains x 2. I expect it's NOAK to be very low. I'm guessing at all of this. Regarding it being a 10.5cSt, 1 or 2 cSt really isn't that significant. A 30wt oil oil that is very shear stable, which this oil has to be, would be great. Look at the UOA's of the 20wts. This is just my opinion but I'm fairly confindent in it so far.
