I agree that wear metals are fine, all I'm searching for is a tad more viscosity, seeing that this car sees 3,000+ rpms for extended amounts of time (1-1.5hrs) daily. Given that this engine has one of the highest piston speeds of any modern honda motor (very close to the s2000) I think I would be fine running a better suited 30w, say a 10w30. The 1st oil change in the report was actually 0w20 M1 AFE..
Appreciate your point of view though. I was debating between a 10w30 and 0w40 but wanted to give the 0w40 a shot.

You're now 2 grades thicker than Honda specs for this motor.
What are you searching for? You're wear metals appear fine even though it's now a thick 20W oil. Obviously the engine didn't care. What results are you hoping for with a 0W-40? Would you be fine if it stayed in grade but your wear metals elevated?
I said it last time and I'll say it again. Until you run a 0W-20 for the full length of the MM for several OCIs to establish a baseline, you have no idea what you're chasing.
Where's DNEWTON3 when we need him?
