High Performance Lubricants No VII series engine oils.

Boy would I ever like to see a UOA that would prove that myth!

Good that you shared this one with not many miles otherwise they would say that the oil has gotten very bad and thick, while this is not the usual bad thickening(Oxidation won against shear). Like if you tell people that this oil is Pennzoil 0W-20, then it looks very very bad, just like a pile of 3 years and 20,000 miles old oxidized crap.

Looking at all those oil viscosity choices it made me think, if we don't stick with numbers like 0, 5, 10 etc, would it be easier to mix an oil like say 3w-28 that would be also better in several aspects than 0w-25 or 5w-30?

How would you define "3W" as a Winter grade that would make it any different from 0W or 5W? Same goes with "28", that's a very specific number, while grades are ranges, I'm not really following the logic here?
 
I should have mentioned oils like 0w-8, 0w-12 (I thought it existed) and 0w-16, they are not numbers with a multiplier of 5. That's what I was sorta thinking. Taking it further, the numbers don't need to be even ether. Some people mix store bought oils of different viscosities and those blends should result in making quite odd oils, what if they were offered by producers?

Yeah. And what do we get if we mix 2 quarts of 5W-30 and 0W-20? Will they even harmlessly mix?

SAE 8, 12 and 16 were broken out of SAE 20, so they are all narrower bands than SAE 30/40/50/60.

Since all the grades are ranges, you are never going to get "odd oils", you just get heavier or lighter versions of the existing grades.

No, because those numbers cover a range of viscosities. The grades are established and there’s no “dead space” between the grades.
 
So the M1 EP 0W20 was at 8 KV100 which is close the virgin I think. But the other oil increased by 1 and oxidation almost doubled?
 
EP went from 8.8cSt to 8.0, SC went from 8.5 to 9.5cSt. So EP lost almost 1cSt, and SC gained 1cSt.
I’d much rather have an oil that has a known, gradual increase in viscosity even in the presence of some fuel dilution, rather than an oil that may suffer permanent shear AND quickly thin with fuel dilution. There’s zero harm for a slight viscosity increase; dropping out of grade can carry serious implications for chain life, bearing health, and contact points like finger rollers and pushrod cups.
