Would a zero Noack oil require less cleaning additives as compared to 10% Noack oil?

I've never seen a zero noack oil but i've seen 3%. Oil is volatile so it will it evaporate and it's not water but hydrocarbon based so it will leave high density heavy hydrocarbons as deposits where it took place which is the piston rings most of the time. But an oil can have ana amazing noack of 3% and no ability to clean and will leave a lot of deposits while an oil with a poor/standard noack like Valvoline Restore and Protect will leave rings clean because it can clean up everything it leaves behind and what was left before it while that 3% oil will deposit little but clean up none of it and eventually build up while the other oil like Valvoline Restore and Protect leaves more deposits but more importantly cleans it up immediately.
 
I'm pretty sure that a zero Noack oil would require an entirely different kind of lubrication chemistry than we currently have, in which case, who can say what some unknown hypothetical lubricant would require?
 
What oil is that?
Usually 50 grade synthetic oils have Noack about 6%.
I'm interested too. I want to say there was an older Pennzoil formulation in 10W-30 that had extremely low Noack. Maybe Pennzoil Ultra Platinum 10W-30?

Red Line Euro 5W-40 and their 10W-40 have 5% which is extremely impressive.

Amsoil Small Engine oils have levels around that. I use the 10w40 in my OPE.

I just looked. Yes, it was Pennzoil Ultra Platinum 10W-30, but in 2104, API SN. It's interesting because the 2nd link below says SN-RC.

Pennzoil Ultra Platinum 10W-30 - Noack 4.7%

I misremembered it was 2% noack not 3%. Chevron 600r by itself could make a thick sae 30 with no vii https://cglapps.chevron.com/sdspds/PDSDetailPage.aspx?docDataId=76663&docFormat=PDF
 
I dont think 0% is possible. Maybe with a PPE (poly phenol ether) used in the sr-71. For what its worth hatcol 2999 has a 2% noack and thats a 12cst POE.
 
NOACK is essentially the evaporative loss at high temp, and it is reasonable to say any liquid would evaporate. So I doubt a true 0 is possible anyways.

But assuming the question is more about "some noack that approaches to 0" we need to consider the ad pack as well.
One would need to find heavy molecular weight antioxidants. Also my udnerstanding is that with the limited P allowed in most oil, blenders have been overwhelmingly turning into low ash dispersant, which are usually more volatile.
 
Thanks!
Well, that is a base oil. It's not a finished product for direct consumer use.

The additive pack barely raises the noack from what I've read and at times can further lower the noack due to the carrier base and inhibitors. However the polymers raise that a bit more. I can't remember what it was but I remember seeing an oil being 2.8% and it was a finished product, that's probably what I remembered as 3%

I just check how much evaporative loss at 250°C for 60 min. has avocado oil. It's just 1-2% evaporative loss. 😁 I use it for cooking (especially frying and sautéing) and on the bottle says 500°F smoke point. However that oil breaks down much quicker than motor oils.:LOL:
