Redline Race Oil after 3k miles on the street

Moly 591
Zinc 1037
Potassium 25
TBN 11

that's it for additives

The primarily street driven car this oil was used in could have had sludge , carbon or other deposits loosened and kicked out of where it was hiding by the PE ester or this could be some new combustion particulates. Never the less with the detergent/dispersant missing from this formulation and the particles not being held in suspension and carried to the oil filter as designed " assuming it was large enough to filter anyway " this would make for some very pretty polished bores eventually given enough time between MOH .

Is it possible that this oil uses a different ratio of PAO to Esters? Matt from Mobil tech said he thinks the base stock is the same and it's essentially an additized version of M1 as GManII said. He did say thouth that he thinks it uses NO VII's and therefore is extremely shear stable. Whether it's HT/HS is 3.5 or not is irrelevent. If it's like M1 10w-30/0w-20 and relies completely on the base stock, then it's solid. If it did use VII's, which I doubt it would, it would shear. ex. 0w-40.
 
Not quite sure i like the Mobil tech speculating on their new oil. Makes ya wonder how much they really know about the OTHER products in the lineup.

(I've never personally called Mobil. However, from the opinions on here, they seem a bit inconsistant in information)

ferb!
 
The additive package looks pretty robust to me ....

I'm not sure where the rumor started (Redline Website?), that racing oils don't need detergents, but it's a completely stupid idea. High temp piston/ring deposits will form almost immediately without calcium and magnesium in the formulation. If you can afford to rebuild the engine weekly, perhaps you can get by with minimal detergent levels. But certainly not for any street engine that is occasionally raced.

As for the vis, the standard M1 does fine in terms of bearing wear. This shear stable oil probably has a HT/HS of 3.2-3.3 Centipoise, which is fine for Japanese and Domestic engines ....

Note to self: EM discovers the benefits of ZDDP ...

They told me that they aren't told anything until it's released. The engineers above them do all the work. Mobil tech, as with any tech dept I've spoken too only goes off the product data sheets. They really don't have the insight like we'd like them have.
 
I was reading a prior thread

quote:

Mobil 1 uses a relatively inexpensive, 3 or 4 Cst, PAO basestock which is thickened using the high vis. supersyn PAO - the SS takes the place of a conventional VI modifier. This makes for a very shear stable formulation, but does little for wear protection or volatility at high temps.

and was thinking that maybe the basestock is different for the new M1R. Time will tell I guess.

Thats awesome! i would not hesitate to ride that all winter!

One thing I can assure everyone is that new Mobil 1R 0W-30 is in the #6 Michael Shank Daytona Prototype Toyota/Lexus race car competing at Daytona and currently in #7 position overall... The oil has provided excellent temperature control for the engine vs. everyone else having overheating problems in the DP class....

The PDS is due out any day now. The latest is it will be out "shortly".

I put the M1R in my Mercedes 4.3L V8 today and it made some of the lifter noise I still had with the GC go away. It a very pungent oil, almost gear oil smelly. It is also darker than the standard M1 5-30wt oils.

I just got the M1R and now doing the freezer test comparing the std Mobil1 0W-30 with the racing 0W-30. Still waiting for it to get real cold - hopefully to around -15F, but at -4F the MR1 seems to flow somewhat better than the std oil. Was not expecting this, but pleased. So this does seem to imply a different base stock. In fact, as I recall, it flowed about the same ss GC did compared to the std Mobil1 0W-30. Hmmm....

The smell, as noted by another post, does smell more like a gear lube. But I did not noticed much color difference. Seems strange to see no API rating nor could I find any mention of SuperSyn on the actual bottle- only on the cardboard box label. Now that is real odd considering all the hoopla about SuperSYn being discovered in racing and the mention in the press release.

A 0W oil is to be no more than 6200 cP at -31F. there should no observable difference at only -15F-but who knows

AL,

Looked again today and could tell no difference. So you may be right,they are very similar. If I could just get it down real cold again. Right frezzer is hanging around -4F.

I have been away a while and was just informed about this thread. The oil sounds like some interesting stuff.

George regarding your comment about everyone else having overheating problems at the Rolex 24 Daytona I have to question your conclusion. How can you conclude that the oil had anything to do with engine cooling. I thought the others were having overheating problems due to mud and tire bits caking up the radiators. Also, I seem to remember that Shanks car was the only chassis of this type. Who is to say that the this design is not vastly more efficient wrt air flow over the radiator and oil coolers than anyone elses. Also, who is to say that the Bell Racing winning car wan't using this oil too. My point is, despite the fact that this oil may have been a factor in keeping Shank's engine cool, there were way too many variables in that event to conclude that the oil was the reason that this car was cool....

Well, If I can ever find it localy I will try it! I might even try it in the summer! I am intrigued buy the "Race" portion of it. If it is not going to be shear stable I think my little hot running Toyota will find it out. While my cams are chain driven my ballance shafts have total of three helical cut gears involved! If it is plain jane M1 0W30 I think it will be obvious when we look at the UOA! The M1 0W30 shears badly.

I do not think that the presence of detergents means much. Not all race oils are devoid of detergents! Redline is the only company I am aware of that does not put any or hardly any detergents in its raceoil. RP race oils have detergents, Amsoil race oils have detergents, synergen has race oils that have detergents in them, valveline VR1 race oils have detergents!

To be honest I do not think that an engine at any 24 hour race would fair well with no detergents at all. 24 hours with an average speed of say 120-140 MPH time max temps well over 100 degrees hotter then our engines see in WOT work etc....... The amount of fuel being burned and the blow by etc..... We also know that some types of calcium when overbased will aact as EP additives for about 1500-3000 miles. The extra calcium also mediates TBN!

Even if they tweaked it for street use that is a good thing! I would rather have a race oil with a few street conscessions then a pure race oil that was going to leave deposits behind in daily driver use!

I sent off a sample for a BlackStone Labs VOA of Mobil 1 R. You can order it by the qt. through autobarn.com. It took 5 days to get here. They are based out of Long Island. I only added a qt. bc I wanted to sample it. Plus, if I wants some added ZDP, I'll mix it in with what I'm running now. Not like these Toyos/Subarus need it though.
