Capable and ideal are two different things. Most of the foreign service manuals I've seen call for 5w-30.
A mod on here with an actual oil pressure gauge reported a drop in oil pressure near redline with ow-20. Most in the know it seemed to have quietly have moved to a 30 weight with this engine.
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.
