I have never given a second thought to mine @ 300K. Is it worth replacing even with less obvious tearing/ripping? As in, could it have very small holes or tears that create an issue?
CR-V burning oil, should I switch brands/weight?

It could have tears, holes, cracks, splits that are not easily seen, but the more common problems are shrinking/shriveling and/or kinking.
If your breather hose (that attaches to PCV) is 300K miles oil, it's an overdue problem waiting to happen. I'd replace that hose and PCV.
If you're not currently leaking or burning oil, then no hurry. You can wait for warm, comfortable late spring weather with comfortable temperatures and no rain to work on it.
If you have a comfortable heated garage, then it'd be a good winter time project on a Saturday. 30-60 minutes parts shopping. 120 min to do the work (because it's your first time).
After you've done it once, it'd take an hour less time your second time.
Well well well. Where's the "any high quality API spec oil, follow the OLM, and you'll be fine" crowd now?
I see some are already here, and recommending switching right back to the oils similar (possibly the same, who knows) to the ones that caused his problems.
OP, just run Valvoline Restore and Protect 5W-30 indefinitely, max 5000 miles, and run a few short OCIs (4000 miles) to start and see what you get in the filter. Only thing I'd switch to besides Valvoline Restore and Protect 5W-30 would be a good Euro oil like Mobil 1 ESP 0W-30. I'd favor a low SAPS oil since you're turbo GDI. And I would only do that once you're getting zero carbon in the filter, and your oil consumption has resolved.
Good luck. Hope you can get it cleaned up. How long has it been going on? Might be able to get it resolved with Valvoline Restore and Protect.
If the non-turbo engine is your VVT sensor / system clean and working

Really, it's that difficult of a job? It seems like it would take me no more than 30 minutes, taking my time. Send me a PM, I don't want to derail the thread.

Replacing PCV and breather hose in a Honda CRV is not easy. Certainly not convenient. Don't even try it in the winter unless you have a heated garage. My cousin did it outdoors, but that was in summer.
The topic of thread is about curing Honda CRV oil consumption. So I think this is on topic enough and I'll be brief (for me).
Changing my Buick PCV is a 15 min job. It has no breather hose to worry about. Easy access to PCV. No special tool needed.
Changing Honda CRV PCV and its breather hose is a 1-2 hr job because it's inconvenient to gain access to PCV & hose due to cramped engine bay and various parts in the way blocking access to PCV & hose.
It's not complicated (anymore than playing Jenga is), but it's a nuisance. You'll see (evil laughing) muahaha!
You'll have to remove and/or loosen various parts to gain access to PCV and hose. My cousin needed me to buy a deepwell socket to remove PCV. I don't recall the size. He might have also needed me to buy some special needle nose pliars with angled tips.
I don't remember all the details. It was 6 months ago. Please do a Google search for "How to replace PCV [model year] Honda CRV". Then watch the how to video(s).
Once you have access to replace the PCV you'll also have access to replace the breather hose that attaches to it (assuming you have the proper pliars to pinch the hose clamps open).
With a healthy PCV and breather hose, oil consumption will probably be reduced, especially if you also use a high mileage 5w30 oil. Likely no oil consumption then (assuming rings aren't stuck). If you think rings might be stuck, then use Valvoline Restore and Protect 5w30.
