Don't have any UOAs to share with you, unfortunately, but I've seen K24s run well on 5w30 in Oklahoma in all weather. That was what we put in most vehicles that requested our cheapest (conventional) oil change at the Honda dealership that I worked at.

I haven't noticed one bit. Just back from a 600 mile trip and averaged 28+ MPG's....which is good for non-CVT Accord with bike rack and hauling 4 adults.
I run Castrol Edge 0/40 in my k24 series engine, runs smooth, zero oil consumption in 6k miles, gas mileage has not dropped at all. Avg 34.4 2012 Honda Accord.
I use Amsoil 5w-20 SS in my `07 Accord 4cyl. It uses 1 qt per OCI which is about 6000 miles for me. I do a 2 year OCI. Only drive it 3000 miles a year.
From what I have read, there is no chance of wearing this engine out even with a 20 wt.

I use 1/2 qt in 6500 miles with the Castrol Edge 0/40. But again the noack is 8.5. my mpg is 34.5 with a 5sp manual. I use that any day over a 20wt.

Why would there be adverse effects?
in hotter climates a 10-30 beats a 5-30, the first # is the starting base oil then viscosity improvers to reach 30, that is unless its a REAL group IV or V synthetic that the 30W passes the 10W spec WITHOUT viscosity improvers!!
