I don't see why they wouldn't. It's chump change to them. But, it is the reason that I'm gonna switch to regular PP for my next change.
I heard it was around .6 cents per bottle/jug to have the qual put on the label?
In this corporate/political world, anything can take place but maybe Shell/Pennzoil thinks .6 cents is too expensive, which it could be when you add up all the bottles/jugs they likely sell.
I also heard that the Ultra would pass that qual already and would have even before the D1G2 qual came out so they said screw you GM, our oil is already good enough, and has been, so why should we have to pay you?
Who knows for sure, but I'd hazard to guess, because GM is pro Mobil now, that something like that is going on.
I would still like to see a comparison if PUP does in fact lack something compared to a D1G2 oil, and if so, how significant is it exactly?
If Shell is willing to pay the licensing fee period (which they are) then it doesn't make any sense for them to not apply that to the entire product portfolio, and there's no financial incentive to defer it if they were paying for the previous generation license already. It isn't like the cost goes up, it's an evolving spec.
As for GM being pro-Mobil, that factory relationship has been in place for 30+ years, so they aren't "pro Mobil now", that has simply always been the case. No different than the FIAT/SOPUS relationship.
I suspect the issue might be still high levels of calcium.
There is all the talk of cleansing re PUP.
PUP appears to be a hair thicker than PP.
ASTM D445 8.8 vs 8.6.
VI 164 vs 167.
@ 5W20.
I used Pennzoil Gold when FF was changed out.
PG has been D1G2/SN+ since early in the game.
Now, I am going to change out PP 0W20 for PUP 5W20,
as I move into the High Mileage realm.
10k mile OCI maintenance schedule will remain.
I am a prime candidate for this.
--75k miles per year.
--decade old engine design.
--FI-VVT..no DI.
--mild winter weather.
--freezing temperatures maybe 5 days a year...never lower.
JMO. If I had GDI, I would stick with PP, probably slightly thicker, and short OCIs.
