And the pretendgineers here are still going on with the old “Honda isn’t what it used to be”.

Yeah I was thinking the same thing, it didn’t look all that clean to me. However the burnt valve had most likely nothing to do with intervals, and the guy did make it to a million miles. Yet I agree, didn’t look all that clean in that intake, the heads had a lot of varnish. Still all this ^^^ is pretty normal for an engine with over 150,000 miles...you’re going to get varnish on a valve train in the rear head on a V6, and you’re going to get soot and carbon buildup inside an intake manifold.
It’s a fun topic but one anecdotal story is meaningless. It proves nothing.How so? What if someone had the exact same engine die at 175K with that exact same oil? No one would ever post that but I am sure it has happened. The oil would not be blamed, and everyone would suspect a one time manufacture defect. Lastly, it’s hard for anyone to explain why thicker oils are recommended by auto engineers outside CAFE regulated USA. That alone speaks the loudest of all, not random stories.

Well, you might have just convinced me to adjust the valves on my daughters 2008 CRV. I did them once at around 100,000 miles, it’s now at 180,000 miles. The engine is very noisy, hear a lot of ticking. It does use a little oil between 5,000 mile intervals, maybe a half quart, maybe more. We’ve had the CRV for so long now - in that time it’s had some great maintenance, and at times it’s had some neglect. A month ago I realized it had gone 9,000 miles on Amalie 5W20 synthetic. It was a quart low too. This is what happens when you give a vehicle to your kids and have too many to take care of.
But I’m going to adjust those valves. Probably change the rear diff fluid too (it’s been a couple years). Passenger side power door lock motor is junk too, might replace that.

Not anymore they don’t. The manual I pulled for the new Type R civic from both the UK and Arab Emirates both show 0w-20 as recommended though they do show options for thicker oils. Toyota Land Cruiser from UAE also shows 0w-20 as “preferred” while listing others. Welcome to 2023

I think it does prove something...that the TYPE of engine means quite a bit...and that group lll synthetics are all pretty good right now.
The big takeaway for me was that there was another courier trying to get to the million mile mark, and he is on his way in a newer DI Honda Accord, and his engine lasted 300,000 miles before he had to replace it.
All part of the CAFE conspiracy to force lighter oil down your throat and cause engines to fail just outside of warranty.
It’s been very well documented. There are others and even more when that particular engine was made.
And those recommendations in the UK and Europe aren't made for a technical reason but a regulatory reason. This has also been explained multiple times but since it doesn't fit a specific narrative this reasoning is abandoned.
I agree with you.
An engine and manual transmission will last a very long time with mostly highway miles and proper care, as long as you have a good engine and transmission to start with. You also need an owner who likes the vehicle well enough to keep it for a million miles (fixing the other critical stuff that goes bad along the way).
So all in all, a million mile vehicle is still a pretty special vehicle.

That would require an OCI every 2 -3 weeks if he put the million miles on the car over 7 years, That is totally unnecessary.
If mileage accrued over 14 years, Even an oci once a month seems too much.
How about 6x oci a year at 12k mi intervals? Looks like a good place for a real ester synthetic and 20k intervals.

None of the Honda international manuals I found show this, even in the UK. It just shows 0w-20 and Honda type 2.0 which is factory fill 0w-20.
I can’t pull Toyota manuals on the computer I have now, but the ones that do give the option do it for high load and speed, which almost none of the thickies are achieving
Which may be true, the fuel economy rules in the EU are similar to the US in regards to owner's manuals. Since the UK CO2 rules are modeled after the EU ones that isn't surprising.
Still doesn't make it a technical reason however, which is what gets lost in this discussion. Besides a somewhat lower fuel consumption there are no benefits to lower viscosity oils.

That may be benefit enough for some people who still haven’t been shown any evidence of x20 being inadequate.
Would I run x20 in my track prepped car? No, of course not. However I have no qualms using it in a 1.5l daily driver that is lucky to break 2000rpm once during my daily commute, and neither should 99%+ of other people
My first car was an 86 Accord and the book spec for adjusting the valves was 15K miles. I did it dutifully many times.
Yes, I bought the factory service manual from Helms.
Thin oils have their place in frigid climates. If I lived in MN or something I would want thin. Living in south TX I run 10-30 and won’t apologize to anyone. It’s the best fit.
In the case of Honda, more so than Toyota, they have promoted longer term plans for becoming more and more environmentally-friendly. If that means recommend 0W-20 oil globally because in the big, big, picture it does offer improved fuel economy (I didn't give a value and no one needs to nit-pick), so be it.
Just proves some engines are designed and made well.
