If you want to run mobil 1, go for the 0w-40 euro formula. One of the main differences between euro approved oil and others is that the euro ones require a minimum of 3.5 Cp ( for the HTHS test)

HTHS = high temperate/high shear

Rotella comes in at 4.0 cp
Mobile 0w-40 in at 3.8 cp
Mobile 5w-30 in at 3.1 cp

Higher HTHS provides better wear protection. Especially for the turbo bearings as oil gets pretty hot in there.
