Not sure if you saw @The Critic's recent 1.5T UOA, but it had 9.2% fuel:

The shutting off and disabling of the vehicle appears to be a result of the oil level getting extremely high. As noted in that thread, there's also an issue with valvetrain wear/failure that's associated with the high levels of fuel dilution.

Not all of them are going to dilute like crazy, it's very dependent on how and where the vehicle is operated. Short trips are not good, short trips and a northernly climate are worse.

Thank you, the first thread didn’t get interesting until a few pages in, and the last est ups shows insane dilution for a newer car. It also seems like you guys were already fighting in several fronts already

Anyway what I got is, keep my OCI at 5k is fine. After next cycle I’ll test 91 fuel for level increase. I’ll keep an eye out of dip level as well, I hope most owners check their new oil level with the oil hot and not just cold, that affects readings too.

Also keep an eye out on Honda recalls it sounds like if there are that many people with the same problems

Yep. My preferred method is take it for a ~20 mile drive, park it on level ground, wait 30 minutes, then check. This usually shows a slightly higher dipstick level then checking cold, first thing in the morning. It's good to be aware of what normal is for different situations. For example, I have a car that when started cold, then immediately turned off, will drop the dipstick level by about half. The oil seems to get "stuck" in the engine and filter because it's not warm enough to drain back into the sump. That is a potential false reading that could cause someone to overfill their crankcase.

The 1.5T has been out for nearly a decade, so this isn’t a “problem”, it’s a “feature”.

Yeah, that thread went pretty wild and somebody has a massive set of blinders.

There are two types of people when it comes to this sort of stuff:
1. The person that acknowledges, accepts, and understands the issue and does what they can to mitigate it, using that knowledge.
2. The person that claims the issue doesn't exist or doesn't matter and will argue to the ends of the earth that this is the case, regardless of the amount of data presented to the contrary.

Clearly, this person falls under #2, you seem to fall under #1, which is nice to see.

That's all you can do, keep both eyes open and do what you can to avoid the problem. You'll want to use OAI/Polaris for your UOA's, since they properly measure fuel dilution, Blackstone doesn't.

Yeah, I remember hearing a lot about it in 2018 (5 years ago) and Honda "fixed" it with an ECU update that didn't really help. If there hasn't been a recall yet, I doubt there ever will be.

As I posted in the other thread I linked, there's a warranty extension due to valvetrain damage, including camshaft and rocker failure, caused by the fuel dilution:

In My Civic sport they won't change the oil until maintenance minder says so. I have 30k now and getting 41 mpg. I check the oil once a week. No issues. I believe it's a fuel quality issue and not a oil issue. I have been using top tier premium since the 90s. Always better mpg.

Better mpg than what?
