I'm surprised such a robust/expensive oil would degrade to that point so early in it's expected life. I've been adding 4 oz Auto-Rx as a dose and I don't get that noise till maybe 12k and it starts up much much easier and quieter throughout that 12k life.
Anyway, I'm planning to try out their new ASL to see if that helps. I'm in SoCal, but noticed that even though the SSO is thinner than the 5W-30 GTX, the cars start up SO SMOOTH and QUIET in 100F weather more so than cold so I'm assuming the 0W being too thin is a bunch of [censored], so it's hard to say what the ASL will do. Worth a shot.
I think post "clean up" (obviously, the engine needed it or else you wouldn't be doing it) any oil would struggle to stay clean and not be good for up to its maximum drain interval.

Very true about the speed, I traded cars with my wife this week and I drove her V6 RAV4 after driving my Prius for a while. I almost lost control of the car during the first difficult lane change. It was that quick and took me by surprise. I still cannot start smoothly from a traffic stop as this thing jerks forward like crazy. Fortunately, it's AWD or tires would squil every time.
Not sure about the piston slap part. I don't have it and people on RAV4 forum never complain of that. Too many noises are blamed on piston slap. I used to have Suabru with piston slap like noise and they were notorious for that. I used mechanic's stethoscope and localized the noise in the timing belt area. It was a defective timing belt tensioner producing slapping of the belt at idle speeds on cold engine.
