If you still want a high VI oil, there is the Catterham blend. Which is 0w-30. If you add a pint of Mobile 1 Racing oil 0W-30 it puts the ZDDP and moly near Motul 300V levels.

When the car is engineered for 0-20w oil.. It's more to it than just vi.
Adding zddp adds phosphorus above the 800 ppm that adversely affects the cats and emissions. More to it than someone's special oil mix. Maybe the engineers know a few things we should listen to.. Especially long term and warranty wise..
