It has been running cheap quickie lube oil for most of it's life, sometimes for too long and low on oil. I got it from my brother at 120k and really took over my own maintenance at 140k. Hence my assumption it is the rings.

It will let the rings become freed up from the piston rings lands.
If the rings can move around as needed, they will seal better.
Gunk in the bottom of the pan isn't hurting anything, and is best left there instead of circulating it.
This will not only help reduce oil consumption, but will pick up another .05 Horsepower, too
(I have actually picked up a NOTICABLE amount of power over a 10,000 mile regimen)
I've been doing this for ~6 months, it slows the consumption but doesn't stop it. I mostly run the TCW3 for the warm fuzzies.
Valvoline PBR is the only purpose made product for carbon clogged rings, and way cheaper than a rebuild which is why I am planning on trying it, I will be doing a 5k OCI as per the manufacturer instructions, with a filter change at 1k and maybe 3k depending on how the first looks.
I'm seeing roughly a quart of consumption every 2k miles, which is about double what it used to be, and that is why I'd like to address this now before it gets worse. I want this car to last, I'm nowhere near done with it yet!
I appreciate all your feedback, thank you!
