Obviously, there is either a bit of difference in the base stocks, or the additives (pour-point depressant and viscosity improvers?)

But if you aren't in the know and don't have the "recipe"..... it would be really hard to nail down the cause.

I think so too judging by the flash points of both..

I also think the PP would be less shear prone

They've reduced moly quite a bit, still more than the majority of the field but a disappointing hit. The lower calcium isn't surprising given the whole low speed pre-ignition (LSPI) requirement of D1G2 but also disappointing. I have enough stashed while I wait for a few UOA data points to see how these new formulations perform.

Hopefully it's just a different type of moly.. it's on par with Mobil 1 numbers I see
