Not sure if it was conincidence or not, but curious if hitting the natural frequency of the engine for extended periods allows oil blowby / burn due to vibration.
Probably pie in sky, but interesting results.

I guess I’m just not used to an engine burning that much oil, that quickly. I haven’t driven the car in a week, I’ll throw another quart in on my next day off, do a check for any noticeable leaks, and I’ll probably just drive it around town for a while and keep an eye on it and see what happens.
