0w16 oils been out for a while now, I was curious if anyone has a high mileage vehicle that has used 0w16 the whole time exclusively.
Any high mileage vehicles that have used 0w16?

125k isn’t very high, but that’s what my 2019 Camry Hybrid has. It has only ever had 0w16. No oil burning, spark plugs looked mint when I replaced the OEM recently. I can still get >60 mpg going 55 through the country. I don’t see any sludge through the fill port or on the oil cap like my 2018 Terrain. It’s had anywhere from 7k to 11k oil changes, oil was never super dark, always a touch of golden brown visible. I’ve used Valvoline, Pennzoil, and TGMO 0w16, but never Mobil 1 directly (TGMO is a mobil derived oil). Also, UnstoppableMileage on reddit had >400k on hybrid Rav4 that was only serviced by the dealer, which means 0w16. No engine issues with his car. However, they were highway miles. Highway miles are not hard on a car.

Our previous Sienna Hybrid went 85K on both 0W16 and 0W20 before it was totaled. That said, the difference between 16 and 20 is negligible and not something to worry about. The two grades have substantial overlap and therefore wouldn’t show any noticeable difference. Both grades are suitable for normal use. So no reason to suspect an 0W16 couldn’t maintain an engine to high mileage.
Any non-hybrid ones? 0W16 seems like a great idea for hybrids, where they can do lots of cold/cool starting, but maybe not so great in a hard working smaller NA motor?
How so? What are you calling hard working?
Ex: M1 AFE 0W16 is 7.6 cSt and M1 AFE 0W20 is 8.2 cSt at 100c (operating temp.) Both of those oils fall into 16 and 20 grade and are 0W rated so they should basically be identical as far the engine is concerned.
Something like a smaller 4 banger in a midsize SUV or minivan or truck. 2.7 in a loaded Sienna into a headwind on a 90F day is turning some rpms and is working hard, 0W16 may not be a good choice those oil temps?
Back in the day American V8s and inline 6s used SAE 10W, which isn’t much different than XW16 all winter long. With carburetors running around half the time with their chokes half on I’m sure the oil dilution was over the top come drain time.
Nowadays with larger sumps and fuel injection, the fuel dilution is a fraction of what it used to be.
Back in the day engines didn’t have oil coolers, so the sump temperatures were hotter then.
Compared to 0w16, I’ll bet sheared down old school 10w30 was thinner at drain time and about the same sump viscosity at operating temperature.

The engine should maintain operating temperature at highway speeds and 90°F just fine. If not there are bigger issues than the oil grade.
I will chime in if this has any Merit. I have a R4 hybrid, using 0w-16 and 20 for the most part. Driving around town, stop and go I seem to have a good amount of fuel smell in the oil.
I'm not too concerned about it since I do some freeway driving that seems to burn most of it off, at least by the smell!
I just recently did a 750 round trip Highway run up to Monterey and back using m1 0w20. I did have it pushed pretty hard for this little four-cylinder, doing 75 to 80 the entire trip. Speed limit is 70 on these interstates and most flow of traffic is 75 plus. Also fuel consumption is much greater at 80 then at 70 specially with a head wind like I had on the way back.
I was surprised to see that the motor oil appeared to be relatively cleaner without any fuel smell at all. So my thinking is that the long ride filtered out and burned off a lot of those impurities.
and these are just smell and color observations no analysis taken. I change my oil to frequent.

There’s a lot of truth in this. I remember how overwhelming was the smell of fuel in most used oil I drained from 60s and 79s vehicles with carburetors.
A high mileage 0w16 could be in the works.
