Use the factory spec. weight and type of motor oil and you will be fine. I would not recommend a thicker oil. The clearances on modern engines are designed for the "lighter" weight oils not the opposite.
Engines can be designed to tolerate lower viscosity oils but none are going to be harmed in any way by an oil with a somewhat higher viscosity. Your post above is typical of uninformed fear mongering we sometimes see on here.

Any SAE grade oil is going to get through the “clearances” just fine as long as the winter rating is appropriate for the expected starting conditions and can be pumped.

You really know how to put the hammer right on the nail. I love it when you do this.

Thanks guys.

OK, another question. factory fill. When to dump it? I have ~850 miles on the car and I am already getting the itch to dump it.

On my '05 Civic I bought new, the manual specifically stated not to dump it early, but I made it to ~1,500 miles before I dumped it.

My Crosstrek manual states nothing like that.
I dumped my '21 Corolla 2ZR-FAE oil at ~1100 miles. Toyota doesn't specify this, but there were visible wear metals when I dumped the filter. I would change it after the break-in period. The mileage is denoted in your manual.

The Car Care Nut specifies to do this and states he doesn't care what the manual says. I 100% agree with him.
