Less Than <2,500 Miles IMOProbably should be doing 3k OCIs on that engine.
UOA's aren't a substitute for tear-downs. If these engines start drinking oil later in life, there's a reason for that.“Although fuel dilution is flagged at high levels there is no apparent wear”
Yea, sounds truly horrible

Have you tried our home remedy of 89/91 octane fuel?
Not necessarily. Wear appears to be normal and the vehicle is still in-warranty. Owner plans to stay with the current regimen (but at 5K drains) until the extended warranty expires in 2027.5%+ fuel is a good reason to dump the oil. What are your plans at this point?
See post #26. My iron level was slightly elevated.Not necessarily. Wear appears to be normal and the vehicle is still in-warranty. Owner plans to stay with the current regimen (but at 5K drains) until the extended warranty expires in 2027.
Wow! Look what that fuel did to the vis. Wear looks ok. Max oci 4,000. JmoTime in use: 7 months
Oil Filter: Genuine Honda
Driving Conditions: lots of short trips
Maintenance Minder was at 30% remaining

Forgot to check before draining.You'd clearly see that on the dipstick.
Here's an older UOA of my 18 CRV. The oil level was high on the dipstick. Not super high, but maybe a few mm above the full mark. Same oil, even lower viscosity. I wouldn't be surprised if my dilution was about the same. https://bobistheoilguy.com/forums/threads/2018-crv-28-4k-m1-ep-0w20-4-3k.353261/post-6076867Update:

How short are the trips? How many miles, how many minutes driving?Driving Conditions: lots of short trips
Maintenance Minder was at 30% remaining
Not entirely sure but probably under 5 miles for most. CA, climate was between 40-80F. Oil was in service for 7 months.How short are the trips? How many miles, how many minutes driving?
What state/climate? What months were most of the driving?
Just looking for information since we own a 21 CRV that showed some evidence of fuel dilution when it had really shirt trips early in its life. It gets longer trips this summer, will do an oil sample at next change.
Thanks for the info. On the fuel evaporation, probably true, but short trips at cool engine temperature raises the percentage of total run time/miles where the engine (really rings) are cool and allow fuel to escape into the crankcase. Lets just say that it takes 5 miles for the engine to warm up enough to stop leaking fuel/air mixture from the cylinders into the crankcase and oil. If you only drive 5 miles each trip (leaking fuel for all of the trip), you are adding a lot more fuel in your 7000 miles than someone who completed the 7000 miles with 30 miles drives (5 miles leaking fuel, 25 miles hot and not leaking fuel).Fuel really doesn’t evaporate with highway drives. Even highway driven 1.5T’s will exhibit this level of dilution.
