Looks like even the Toyota 0w-16 met the 15% limit. Would have to check the API documentation but the 0w-12 and 0w-8 grades may still be excepted.
Why I Switched to 0W8

Answered my own question:
Only 0w-16 is included in SP, 0w-8 and 0w-12, while ratified by the SAE, are not included in the API stuff, they are regulated by JASO, so their Noack can be whatever.
0w-16 was added in 2016.
Direct Rejection’s premium plus 0w8 will have a NOACK right around 13. We have not measured it but base on the raw materials I have chosen that’s where it’s going to be.
Also Elite qualifies and races on the same 0w8 as in the same oil in the pan. It is pretty typical in Pro Stock to change the oil very frequently with other brands. Perhaps even every other pass. The reason for this is the power will fall off very rapidly. We do not have that issue with our Pro Stock oil. So even comparing the normal life of 2 passes compared to our 20 it is still a great factor of improvement. The only reason they would change the oil sooner would be if they are in a humid environment. When they ice the engines (actually they have a chiller) there is a significant amount of water introduced into the oil when the block condenses.
The additive chemistry although it is different overall it is surprisingly similar between Our Pro Stock oil and our street oil. It would be possible to drain the oil out of that race car and run it 10,000 miles on the street. The street oils however will run longer.

Makes sense if you are using something like SpectraSyn Plus 4, which is
Clearly, that's not what the Japanese blenders chasing ultra high VI's with their oils are using, lol.
I would agree with not choosing that strategy.
Yes PAO 4 should be a common choice for a quality product and the pour point of the finished 0w8 of -89F should be good enough.
I'm mostly shocked one can actually drive 80k per year in the bay area. 225 mile daily must take an unbelievable amount of added time, and idling. It is one of the worst road designed areas and most heavily congested in the nation with something like 10,000 people PER SQ MILE...
How does one actually drive 225 miles in a day there?

Given the reasons in the OP about why its not such a silly idea, I'm looking forward to any UOA he wants to show us. I mean, the founder of this site actually experimented running his car without an oil filter for a while, and the UOA that followed did not show a gigantic increase in wear metals, although there was some. Quite frankly I'm surprised there isn't more stuff like this on this site. Not that I want 0w8 in any of the engines in my sig. Its enough for me to run the back specced 0w20.
And what are they running the race with?
Believe it or not, liquids cannot be compressed no matter how thin they are. (Super hot take, very controversial)
The bearings being unscathed in an F1 qualifying engine would be indicative of sufficient oil pressure for the conditions of the rotating assembly.
Unfortunately my passenger car engine has many components that are lubricated by unpressurized oil, and I must accept this reality.

When I see the OP's driving - and his efforts at hypermiling - I can see wanting a 0.7% increase. So, 80,000 miles/year. The 0W8 increases his MPG by 0.7%, which is roughly the equivalent of 560 miles of free driving. Given gas at $4.00+/gallon, even if he averages as much as 40 MPG he could be saving around $50. The lower the MPG, the greater the savings...so... Why not run it and try it out? The HPL product is good for an extended drain, so he would be saving operating costs there as well.
Personally, I would be driven crazy by that much exposure to Bay Area traffic, but that's a separate topic

The same oil. They will qualify and race with the same oil in the pan. We have about an equal amount of pro stock cars that qualify and race on our 0w3 pro stock oil.
I didn't know you were talking about drag racing. (A few seconds of full throttle operation). You wouldn't see NASCAR teams using that low of a viscosity in a 500 mile race on a Super Speedway.
Liquids can be compressed all day long. So can solids.
reminds me of a foods- "after being opened, consume immediately."
with such high noack %, i think this will be not a problem to fulfill..
You the man
The debate on compressing liquids in the environment we're talking about (journal bearings, rings/skirts, etc...) will factor a lot with the oil's EHL oil film thickness and pressure-viscosity coefficient. To make things more complicated, both of those factors vary with temperature. Speaking of temperature, specific heat is a consideration since it tends to be lower with lower viscosity oils. The volatility gets dumped on top of that.
I’m looking forward to UOA on this test! This coming from someone who considers full synthetic 5W20 “thin”!
