Then I suggest you do not deviate from that grade.
Does anyone run 5w30 in new Honda?

All CAFE driven - many other new car OMs show only one viscosity too. Toyota OMs however do have a statement to use higher viscosity oil under certain driving conditions. CAFE hasn't brainwashed them entirely just yet, lol.
It's pretty obvious when they tell you what grades to use. Motor fails, and if they see that you put the wrong oil in there? That there's ticket to voiding your warranty. I don't know why you guys enjoy playing stupid.
They would have to prove that thicker oil was used, and that it caused the damage. No car company has a real tribologist that could technically prove that 5W-30 blew-up an engine that specified/recommended 0W-20 or 5W-20. Not gonna happen unless someone was using a W rating way too thick for the cold start winter conditions.
Besides, no engine in the world that specs xW-20 is going to blow-up or be damaged by xW-30, or even xW-40. Why don't all those cars in orher (non-CAFE) countries with the same engine blow-up on the thicker oils that the manufacturer specs/recommends?

Ditto using 5W30 on my 2015 Civic, wife's 2020 Honda Pilot and our 2012 Tundra.
I’m curious if using 5w30 will help with oil consumption
Which brings us back to the original point made by @kschachn
Looks much better indeed!
Why...... If they call for 0w20.....then use 0w20.....pretty simple...
Not Hondas but I run up a grade in most of my cars. 5w30 in my Sante Fe spec’d at 5w20. Legacy gets a 60/40 mix usually of a 20/30 grade. Forester get 10w40 in the summer. If cars couldn’t run on a higher grade than what’s on the cap how would we ever drive them before they get to full operating temp? Isn’t that when the engine oil actually falls into its specified grade? Before that it’s thicker.
What rpm's are Honda's running with the CVT's? My Outback will put the motor down to 1100rpm in town and still accelerate the car with low throttle inputs which is why I've switched to 5W30 syn from 0W20. Even with MPFI and no fuel dilution issues, at the end of a 6k OCI I always though the motor sounded a bit louder/loose with the cheap dealer 0W20 in there. With Mobil 5W30 syn it sounds quieter.
why yes i do from march to september....
Actually it says "The failure of any part or accessory due to: ...the use of a fluid other than specified by Honda". A little different from saying Honda won't cover an engine simply because of oil grade.
That "due to" is important. It says Honda isn't responsible if you use off book fluids and they CAUSE a failure. It's up to you to make sure you don't start 20W50 at to low of temperature to pump or operate 0W-8 at to high an oil temp to keep adequate bearing clearance.
That said I wouldn't use off book fluids (either viscosity or approvals) during warranty because I see no reason to open the possibility of an argument over coverage.
Why 25k miles?
I agree. "Must" or "Required" would mean just that.
Just checked my Honda Manual.
"Recommended".

Yep, I'm still waiting to see an owner's manual where the call out for oil viscosity is "required" and that there is a specific statement that says the engine warranty will be null and void if the called out "required" viscosity is not used.
And just because an owner's manual only shows one oil viscosity, that doesn't mean that it's the "required" viscosity and the only one that will work without causing engine problems. If that was true, all the other vehicles using the same engine in other parts of the world would also call out that same single viscosity, but that's been shown over and over on BITOG that owner's manuals for the some engine in other parts of the world show a large range of recommended oil viscosities based on ambient temperatures the vehicle is used.
