Like others have said, nothing wrong with using an off-the-shelf 0W-20. But if you really want the thinnest oil available while maintaining sufficient HTHS for this engine, try this:

A viscosity index of 239 is nuts and is the highest of any oil I'm aware of. The downside is low TBN, which means you don't want to run it for long intervals, maybe 5000 miles max.
