It’s not. Take a better look.

It’s not. Please take another look.

Maybe I wasn’t clear enough. The two oils on the right hand side of the chart are Dexos 1 Gen 2. All the others are not.

...Valvoline modern engine is. The QSUD sure looks like their D1G2 formula.

Thanks. Just confirmed that QSUD is Dex 1 G2 approved, so I’ll move it to the right hand side with the other two Dex 1G 2 oils. The sample was a bit light on Boron but otherwise similar. I cant’t confirm if the Valvoline Modern Engine is Dex 1G2 but if it is, it’s a bit light on Boron as well so a guy couldd conclude the specs on Boron are not as tightly controlled as the other components.

It's D1 G2

It's D1 G2

OK, thanks, so therefore, the Boron is not tightly controlled of the Dexos 1 G2 oils.

Nice chart!
I'd like to mention that Valvoline is one of the few oil makers today that shared NOACK loss information with us, and they have the VME 5W30 at 11% and the VFS 5W30 at 9.3% (just put the latter in my DIT engine yesterday). I was a bit concerned by the "low" 100C viscosity of VFS 5W30 (Valvoline's PDS says 10.2 cSt), but its HTHS was actually kind of high for an SN/GF5/d1G2 oil at 3.2 (3.0-3.1 are more common).
I'm very surprised that the flashpoint for the PPPP 5W30 came back so high (238C), SOPUS' own PDS indicated it was not much over 200C.
