2019 Honda CRV 1.5L 51k mi; Kirkland 5w-30 4k mi

The viscosity likely dropped due to fuel dilution. Blackstone fuel dilution numbers are meaningless. Your viscosity looks like its Xw-20 range, so you made a right call using higher viscosity oil.

Find an oil that doesn't shear anywhere near-as-much.
Mobil-1 EP 5w30 may be another $10 more and worth it.

I used M1 EP 0W20 in my CRV and viscosity dropped from 8.5 to 5.8.

Looks like our CRV is not immune to the fuel dilution bug. The oil was in use from 8/22/21 to 3/19/22. An unseasonably cold winter was in there and lots of short tripping. We live in a small town, so most trips are 3 miles or less. What's in there now is Castrol EDGE 0W20 black bottle with a tiny bit (~ .5qt) of Castrol Euro 0W40. We're going on a road trip soon that will encompass over 2000 miles, so I anticipate a better UOA the next go around. What's interesting is I measured about 3.8qt when I drained this, which is just slightly more than the sump capacity, so I wasn't expecting the...

I had the same experience in Honda 2.0t with Mpbil1 EP. Fuel dilution can not be helped even with best oils

True. But you can go up a grade, to 5W-30. Honda turbo 1.5 and 2.0 engines use that grade in many parts of the world anyway.

I am using 5w-30 Kirkland, and change it every 4k miles. No need to buy expensive oil.

I would have asked them to rerun the viscosity and the flashpoint. I have my suspicions one of them is off. That's very low for an oil that likely started close to 11.0 cSt.

If you still have some oil from that lot number a VOA might be interesting. I have gotten 5W-30 in 5W-20 bottles before and it's possible you got the opposite.
