This is Big 10 country! 0-30 is thick sauce in these parts.

I love Toyota's, but only up until the year 2017 (as that was the last year that 20 weight oil was speced).

The difference will be small but you will not get the same MPGs with 0W30 compared to 0W8 factory fill.
There should be a 1.5% improvement in fuel economy going from 5W30 down to 0W20, another 1.5% dropping to 0W16 and 1% more going down to 0W8. Therefore if your Camry has a combined rating of 50 mpg you will drop that down to about 48 mpg by running 0W30. Maybe not that significant for you but it is over thousands of cars on the road.

The 2025 version is a great car. Word is they're pretty reliable. After owning this one, with its planetary gear set E-CVT and electric power, I'll never go back to an ICE-only car with a traditional transmission. This thing is a smooth boat. Quiet ride too. Instant torque available at any speed. Cost effective. 0W-8 is crazy. I bet they change the recommendation back up to 0-20.
You don’t have to use what they recommend. My wife’s 2022 Camry recommends 0w16 and it gets a steady diet of 0w30/5w30. Personally, I wouldn’t let that deter me from liking newer model Toyota’s.
That might be true, but I've been tracking my exact gas mileages for over 10 years in an Excel spreadsheet, and when I switched my 3 2006-2007 Honda Odyssey EX-L's about 4 years ago from 5W-20 to 5W-30, there was no measurable difference down to a tenth of a mpg with 5W-30. My suspicion is that the fuel efficiency gain with 20 weight oil might be < 0.1 of a mpg, but still important to auto manufactures in lessening CAFE fines over 1 million+ vehicles.
In my case, I wanted the higher HTHS protection of a 5W-30 due to the generation of Honda Odyssey which I own having a poorly designed PCV which allows the cylinder heads on the front bank to get extremely hot. As a rule, all oil gets thinner as it gets hotter.
I prefer the added HTHS Moft protection of a 5W-30.

Especially if it's a Toyota vehicle with the 0W-16 factory fill and their smaller-than-a-riding-mower's " rock catcher " oil filter.
Or, look at VOA of Toyota factory fill and / or Toyota 0W-16 GTMO synthetic. HPL PPPCMO and their No VII is about the only other oil that I have used that comes close to the high moly level in the Toyota oil.
Double True for any hydraulic, transmission or gearbox. Get those wear metals out and clean the magnets!

Here’s mine at 4912 miles, 1st oil change as well.

Currently running 0W-16 for my first change at 1k (1.2 to be closer to exact) and I definitely notice a change in my MPG's. Same commute I was getting (on the dash) 56-58 MPG and now I'm getting 48-50 MPG. And it feels like I need to feather it more. Honestly was not expecting that much of a change but I'm also only on my first tank since the change. I'll do my UOA at the 2nd change but I'm also going to go back to 0W-8 for the winter. I don't plan on pushing the 0W-16 for very long, 5k max. After about the 3rd UOA I'll likely stretch to 7k changes but no plans to push to 10k.
I have no personal opinion on running thicker oil. I'll stick to what's advised since it's under warranty and I treat every new vehicle like a 3 year test run. Just thought I'd add to the thread as some have mentioned a slight change in MPG going up in thickness which is to be expected for the most part.

Thank you for posting these FF UOA. These give evidence that the Factory Fill is not the First Fill in my opinion. I still marvel that 0w8 is a thing.
How many miles on your Camry? The engine is still breaking in. I have almost 15,000 miles on my 2025 Camry now, and with M1 AFE 0W-30 oil, I'm averaging 54 mpg with a mix of city and highway. If I drive on this one flat 10-mile trip and go easy on it, keeping it under 55mph, I sometimes get 75mpg. I got 89 once really late at night with no cars on the road. Driving normally it gets around 60 or 65mpg usually. I can tell my engine is running a lot smoother and quieter than when it was new with 0-8 in it. I think it broke in. When I take 40-mile trips on the highway going 70 to 80mph, it averages about 51mpg. So I'm not too sure 0-8 would improve the MPG's one bit. Even if it did, I would never use 0-8. Just looking at it pour, and looking at the old oil as it comes out like water... and then knowing why car manufacturers recommend it (to get brownie points and avoid fines and be in the green club) I'm never gonna use it.
Have they started changing oil recommendations yet? Because the stupid EPA CAFE mandates are being wiped out right now, are they not?
