Wow, the NOACK difference between Pennzoil Conventional 10w30 and Quaker State Conventional 5w30 is nuts!!!
4.4% vs 11.4!!
GTX isn't that stellar either at 11%. Really only Pennzoil conventional looks good from the bunch. Thanks for sharing Tom
Just a NOACK summation:
Pennzoil Conventional 10w30: 4.4%
Quaker State Conventional 5w30: 11.4%
GTX 10w-40: 11.0%
Havoline 10w-40: 13.1%
Safeway 5w30: 12.7%
Peak 5w30: 14.4%
Accel 5w30 14.9%
The last two really pushing up on the 15% limit.

I'll stick with te good ole' Quaker State Conventional; never had a issue in all my years using it. May make a PYB/Quaker State Ultimate Durability brew in the near future

They're dino, not synthetic. 11% is fine for a dino. There are full synthetic oils that have higher NOACKs!

Why does 10w30 Pennzoil have that kind of noack? What trick is used to get a conventional oil to hang around when heated?

"fine" yes, but PYB's is particularly low, and that's what stands out. Compare it to this 10w30 they also tested:
http://www.pqiamerica.com/June 2014/tLifecycle10W-30.htm
With a NOACK of 12.3%.
Anything below 15% is "fine" but when looking at the numbers, one would generally inclined to lean toward the oils that are the furthest below that limit.

BigD1: my guess for Pennzoil conventional low nock is the GTL base stocks we are hearing and reading about
. Maybe OVERKILL knows more than my mechanic brain does; dunno
My theory is the flagship product is still, after many years, Pennzoil Conventional.
So they have no qualms about dumping excess GTL stock into yellow bottles to get rid of it, as Synthetic oil still isn't a big seller compared to cheap dino.
And, if anyone "finds out" this is what is happening, well, Shell can just say, "We told you it is awesome oil, not dipstick marketing."
Also, I would guess that the "cheaper" add pack of Pennzoil Conventional gets a boost from being blended with, bar none, the best oil basestock currently on the market.
Also, the ultra low Noack would help out with Pennzoil cleanliness claims, by just not burning off and adding to a dirty engine even if it isn't really cleaning much.
I ran Pennzoil Conventional before my current fill and it was really quiet oil.
I have ONE jug left, I wonder if there will be another $9.99 Walmart Boxing Week sale on the Pennzoil Conventional 5L jugs again!!

GTL not in Pennzoil conventional yellow. That we know of.
Pennzoil Conventional 5w30 NOACK is 14.4 per PQIA test done. Just seems strange how this 10w30 conventional oil is 4.4. And the Platinum 10w30 is 4.6 and CCS is 4150. And thus conventional oil has a CCS of 4130. I may be wrong but just seems far too similar to Pennzoil Platinum 10w30. I am willing to bet there was a mix up and Platinum found its way into a Pennzoil Conventional bottle.
I would like for these latest results to be true indeed. Because that is a fantastic result. And I am running a mix of Platinum and Pennzoil Conventional in the lady's Camry right now.

I think the Moly in the Pennzoil conventional sample would flag it to be, in my mind, not a lab mix-up with a Platinum sample.
This folks is just great, inexpensive oil.

Have you seen any 10w30 Pennzoil Platinum VOAs ?? The 5w30 Platinum does not have that much molybdenum in it for sure. But that may well be different in their 10w30 offering.
Again, I really like Pennzoil in all of their offerings. I got 9 qts of Pennzoil Conventional and Platinum recently. All for $34.

Ok agreed... I think BITOG should have a small Q&A forwarded to SOPUS over this as I'm going to speak for myself and say I'm SUPER intrigued by these results.
I'll state that I am a low Noack fan, so I'm going to read the posts!
