It's a 10W-30. 10W-30 oils always have very low NOACK. 20W-50 would be even lower. What's the fascination about NOACK? Base-oil quality is determined by both NOACK and CCS together. Find me a 5W-30 with the same NOACK and then that oil actually does have quality base oil.

5% NOACK is not unusual for a Group III+ 10W-30.





So, the NOACK is not just a function of base-oil quality but also the viscosity. Within a given base-oil quality (an API Group such as I, II, III, or IV), thicker the oil, less will be the evaporation hence less the NOACK. You can achieve the same NOACK for a Group II 20W-50 that you would be for a Group IV or GTL 5W-30.

In other words, NOACK doesn't directly indicate how well an oil cleans or how long an oil lasts. You can have a Group II 20W-50 with 5% NOACK but that won't be a cleaning or long-lasting oil. NOACK is only low because the base oil is thick and therefore evaporates less. It will still break down and cause oil deposits as any other Group II.

Yes lower is better and 5% is very low. That's why narrow viscosity grade oils are so great, given they give you enough cold starting for your climate.

Look at the Noack limits
For API SN it's 15%
For Dexos1 and ACEA A5/B5 or A3/B3/B4 it's 13%
For MB 229.5 or MB 229.51 it's 10%

Given the natural low Noack of oils like 10W30 it's a shame it's not considered a "modern" grade and it's not a Dexos grade.

Still 10W30 and 15W40 are still big in heavy duty HDEO oils. Yes the old 20W50 was low too, but not many people use that anymore.

Still not everybody here is scared to go old school, here is a recent (2017) UOA of GTX 20W50, and it did very well, only 1 ppm iron wear in 3000 miles. That is very low.

Gokhan's Shell graphs basically prove QSUD is GTL. Its a SOPUS product, so there you go. Like Pennzoil is GTL.
Notably, PQIA says low NOACK may mean better oxidation control: http://www.pqiamerica.com/Testdescriptions/Noack.html
Low NOACK should also mean not as much flashes off the cylinder walls and stays in the oil control rings for better lubrication.

It's not the narrow or wide viscosity grade that makes NOACK low or high. It's the "x" in xW-y, it's not the "y minus x."

For example 5W-20 is a narrower viscosity grade than 10W-30 but NOACK will be similar to 5W-30 for a given base-oil type.

See the plots I posted above.

Likewise 10W-30 and 10W-40 will have similar NOACK, despite the latter being a lot wider.

Again, how low the NOACK or how thick the oil alone doesn't determine oil quality. It's the type of the base oil that determines the oil quality. You will still get a dirtier engine with a Group II 20W-50 in comparison to a Group III 0W-20, even though the former could have a lower NOACK.

The plots I have are for CCS @ -20 and @ -30 C. The datasheet has CCS @ -25 C. If you interpolate, it looks more like plain Group III. GTL or PAO would have about 1% NOACK for that CCS according to the plots.

However, Shell's GTL doesn't seem to be of high quality and the NOACK values we have been seeing with Pennzoil Platinum PurePlus have been very high for a GTL. But then GTL is also classified as a form of Group III. So, it could still be a GTL with good cleaning and oxidation properties.

That's not clear. It could also be plain Group III. The plots I have are for CCS @ -20 and @ -30 C. The datasheet has CCS @ -25 C. If you interpolate, it looks more like plain Group III than GTL to me.


I love how you always speculate. Saying "it LOOKS more like"

Present actual facts please

Thanks

Another reason why I like reading SR5's info instead of your heresay

Is reading the CCS value from the datasheet and inserting into the plot to see if it's Group III or GTL speculation?

The datasheet says CCS @ -25 C is 3750 cP. Insert this into the first plot and you get NOACK about 2% for GTL. However, that graph is for -30 C. CCS would be a lot more at -30 C than at -25 C. So, this would give a NOACK between 0 to 1% for a 10W-30 with 3750 cP CCS (@ -25 C) made of GTL, according to the plot. Datasheet says 5%, which puts it in Group III rather than GTL.

However, Shell's GTL has been of low quality and of high NOACK as I said. They operate their gas-to-liquid reactors in Qatar quick and dirty just to reach Group III quality instead of what GTL is really capable of. So, it could still be cheap, low-quality Shell Qatar GTL.

Basically SOPUS knows this stuff. PP/PU appear to be higher quality products but we don't know how much GTL they use in QS stuff and the quality

Yes I agree, but I was just using the vernacular, but thanks for making it clear for new readers.

Sometimes it's good to look at real finished products all from the same company and at the same product level. Here is the Valvoline SynPower PDS which lists Noack volatility %.

http://content.valvoline.com/pdf/synpower.pdf

Noack

ILSAC Grades
0W20 = 12 %
5W20 = 10 %
5W30 = 10 %
10W30 = 10 %

Euro Grades
5W30 = 9 % (CCS = 6100 cP @ -30C)
5W30 = 10% (CCS = 5800 cP @ -30C)
5W40 = 10%
0W40 = 9%
20W50 = 8%

So going back to the OP's point, yes I do think 5% is good for a finished and real oil product. I'm also a little surprised that the SynPower 10W30 isn't a little better, but I will get over it. The best Noack here, is the synthetic 20W50 but no big surprises there.

This was link was posted in a recent thread, and it's Noack figures are given to one decimal place. Probably a better data set to look at.
http://content.valvoline.com/pdf/valvoline_full_synthetic_with_maxlife_technology.pdf

It's for Valvoline Full Synthetic with MaxLife (2016)
noack % for ILSAC grades
0W20 = 11.4 %
5W20 = 9.3 %
5W30 = 10.2 %
10W30 = 6.3 %

That is more like what I would expect in a finished product from a good name brand company.

One cannot assume that 10w30 will have low noack.
And yes qsud lineup is gtl based. Group iii.
