I’m sticking with Valvoline, but can’t decide which would be better for my 25 CRV 1.5 turbo. I do 5k oil changes with a Honda OEM filter. The extended protection has slightly more zinc and phosphorus in it than the restore and protect

Something you should be aware of is I owned a 2015 Honda CRV I purchased brand new. 2015 was the last year of the 2.4L non-turbo engine being put in. After that they started using the same engine you have, the 1.5L turbo engine. I sent in an engine oil sample on one of my 5000-mile oil change intervals. It came back with fuel dilution, red flagged by Polaris labs that took my 0w-20 engine oil down to a 16-weight oil. I thought Honda would engineer the significant fuel dilution problem out of their next CRV release. I was wrong. They made the fuel dilution problem worse on the new engine, they decreased the displacement of the engine, added horsepower and added a turbocharger. On the 2.4 engine, the fuel dilution was a serious issue. Honda spent a few of their hours and my time doing computer program adjustments that their engineers came up with, I went in a few times for this. Ultimately, nothing changed as far as the fuel dilution issue goes on my 2.4. What amazes me is Honda had to know of this problem; however, they released their new 1.5-liter engine that has even worse fuel dilution issues then their 2.4 non-turbo engine had. Honda is not used to their mainstream customers drawing engine oil samples. Most people don't even realize there is such a thing as engine oil or lubricant sampling. My suggestion would be, draw an engine oil sample on your new Honda at 3000 miles, if the test comes back without too much fuel dilution, then test again at your 5000-mile interval. I would use Polaris Labs. The best way to get the kits would be Oil Analyzers, which is Amsoil. Amsoil uses Polaris Labs. Bitog has a Amsoil Bitog sponsor. Check him out, he is @Pablo. He can probably get you set up with some kits. Anyhow that is my advice, and as far as the oil choice goes, buy the highest viscosity @ 100 degrees C 0w-20 engine oil you can find. Of the Valvoline products, they make three products you can use I think, they are all good oils. Pick the thickest one of the three and use it.

Generally speaking, fuel dilution is not a major concern with most k-series engines, which actually are among the best engines made anywhere. I don’t think it has much to do with the 1.5 T, which in spite of some fuel dilution, is in fact a solid plant. Maybe some of the late 2.4s suffered with low tension piston rings and had some dilution. What is true in both cases, is that most problems are resolved with 4-5k OCIs.

I still think he should pull some oil samples, it doesn't cost that much, and there is a lot of info. Maybe do it a couple times, if nothing shows up, don't do it anymore. I do know the Honda 1.5T had worse fuel dilution issues than my 2.4. Maybe they fixed the issue, or like you said, maybe they concluded it doesn't matter.
 
While under warranty 0w20 is the flavor it’ll get.
I understand. I looked this up, and it doesn't appear the manual makes any mention of 5W-30. Usually there's always a caveat. Maybe someone with more knowledge on Honda engines will know if they have different recommendations for different countries like Toyota does. As detailed above, the fuel dilution is an issue, which can be helped with a thicker grade and short OCIs (which you're planning).
