Planning on doing an oil change with this. It's an excellent oil.

Yeah I understand what you are saying. But a 0w still has better cold flow properties than a 5w at room temperatures.
Thing is, ambient temperatures are important, but engine design determines the oil needed. I know that some guys in warmer climates even race using a 0w20 or 5w30 with no issues in the FA20 engine. I personally use to run a 5w30 even for track days in my Honda.
I fear a w40 might be to heavy for the state of engine design.
Think I will lean towards either 0w30 or 5w30 oil to get the best trade off
