The engine was not "designed this way". It resulted from the engine being fitted with low tension piston rings, in an effort to improve CAFE mileage numbers. The severe fuel dilution problem was an unplanned result..... Among other things.
You Can't Change Your Oil Too Much!

Do you honestly think diluting lubricating oil with gasoline by as much as 20 percent is going to improve longevity? If your Honda was suffering from this problem, you would more than likely be screaming the loudest........ Not to mention changing your oil more often to offset the effects.
How do you figure the filter's bypass valve is open most of it's life? Been watching Uncle Tony videos lately?
Man... Do yall know how to party or what?! 
I'll bite. Who is "Uncle Tony".How do you figure the filter's bypass valve is open most of it's life? Been watching Uncle Tony videos lately?
Some guy that fundamentally misunderstands how oil filters are constructed and how bypass valves work.

And many other things, lol.
If it was an issue there would be 3,000 OCI's by the manufacturer. I understand that most on here are smarter than the engineers who designed the motor and spec'ed the OCI.

Blackstone and fuel dilution
Is there a problem with Blackstone's fuel dilution numbers on their reports? On another thread I have going someone made a comment that made it sound like my prior blackstone labs report's fuel dilution isn't anywhere near accurate. I've always used blackstone and haven't spent much time on...

Blacksone & fuel dilution measurement...
posed a Q to Blackstone, would like more opinion please.. Q: Have a Honda 1.5 Turbo Civic and concerned about fuel dilution, my question is are you able to determine the percentage of fuel in my UO and does a concerned customer really need a follow up after flashpoint analysis with...

Fitting them with these rings = "designed".

The problem seems to be most prevalent in northernly locations with cold temperatures. Engineers, working on a budget, and within a time constraint, may not have adequately factored cold temperature operation into their design and testing. That's where the whole issue with China arose from, and then, not surprisingly, a class action lawsuit in Canada.
Mistakes happen. Toyota's sludger engines were designed by Engineers, do we get to just hand wave that away? Same with the Saturn 1.9L. Two engines, from different manufactures, both managed to be designed with inadequate piston oil return holes.
Rod bearing failure on numerous BMW high performance engines.
Subaru head gaskets.
Ford launching spark plugs in the 2V engines
If we are going to compile a list on how times engineering gets screwed up, we are going to be here a while.
The deference to "bruh, you don't know more than the engineers" intentionally not just sidesteps, but Mary friggin' Poppins magic Umbrella's you over the myriad engineering FUBAR's that have happened as a result of penny pinching and time constraint that then have to be dealt with after the beta testing on the public brings it to light.
Uncle Tony on oil filters.
I found this interesting and thought I'd share it. If anything it reinforces that your oil filter bypass pressure needs to be the right value for your vehicle.

The issue being as well...we don't even know if 5% is 5%. According to previous posts on the subject.

Here is what Castrol has to say on the subject of fuel dilution on engine oil. I can only imagine it's as bad or worse with gasoline.
www.castrol.com
"A long-term condition of fuel dilution can lead to premature failure of the engine bearings, as well as aggressive wear of high-pressure points such as the valve train and piston rings / cylinder walls. Although a main concern involves long-term damage, if the fuel dilution is severe enough, catastrophic failure can occur over a short period of time."

I'm not talking of my engine blowing up.
However, I don't want to start putting a quart in every 500kms.
I want my crummy theta2 to last.

I would argue that the engine is perhaps at its driest, meaning void of the most amount of oil at the time of oil change. Even if you can fill the filter with oil, it is not fully soaked and any valve holding back upstream oil would be drained and full of air. The time for the engine to begin full lubrication would be at its longest.
So, I would disgree with
as is the consensus that most engine wear happens at cold start. I am not so sure about this, as I have thought that perhaps it is the combo between the lack of oil and the intial force it takes to get things moving from a dead stop, if more than what is needed to keep it moving. Who knows, I am sure that some super scientist on here will tell you the real deal.
To your second part of the statement as to where you speak of oil not being "used sufficiently, I do notice that my engine in my work truck seems to quiet a bit after the oil change. The exhaust note seems a bit smoother. I have no cats and a straight muffler so I can really hear what comes out the end. This is a personal note and nothing really to back it up.
This may or may not have an application to this conversation, but I sharpen my kitchen knives and all knives really with a "traditional' japanese method. Without getting too much into detail, the method requires use of water and a soft stone, and finer stones as you progress. The slurry created by the stone and knife friction is what really does most of the cutting. There is a certain "smoothness" to the sound once you have set the edge of the blade in reference to the stone. When the edge you set is true, the knife will slide much easier and sound different than when you start. Kind of hard to explain, hope you get the point.
Great post. Thanks

using old pennzoil paraffin wax in liquid form, I would have changed the oil every 2k too. Probably used no oil becasue of the sludge left by the Pennz

I am big on all the other stuff like brake and PS fluid aswell, so yes you guessed it..............I am not overachiever though like most on here

So you can’t show me any real example? The engine has been around close to a decade, surely there is something out there
