Still consumes if I drive over 3k rpm (technically 2.9k rpm; it'll consume slowly if I drive 75mph

)
As much as I try to not let it drive too high, I still got consumption on those instances. Had to make up about 10 oz.
I added a catch can--its a clear polymer type, with a bottom drain screw. The screw weeps oil, so it is difficult to determine how much accumulated over the OCI, maybe 3 oz? The accumulation rate in it does not correlate to significant drops in level during daily checks of my dipstick. Its definitely odd to me, but I'm very confident. Best I can reconcile is that the accumulation in the catch can is unburnt blow-by.
I've switched to splash blending E85 midway through this OCI. I wanted the clean burning benefits of ethanol, and since I go through a whole tank in under 3 days, there's little chance of corrosion due to water pickup. I started with blending a little in at a time to slowly increase the fuel trims and not set off any lean-running codes prematurely. I finally tripped the code at a 25% fuel trim. That was when running over 50% E85, so I've backed down to 50% E85 so as to not ask of it more trim than it can give. I put Gumout Regane in the tank just prior to this change. If all goes well, this would be another step towards cleaning rings in a way that doesn't involve removing the engine.
I'm very grateful that my consumption has come down as much as it has. So far, the things that have correlated the most to the consumption actually
reducing has been the double-dosing of Rislone. Thick oil is burning the least during cruising and I figure that at 3k RPM the PCV valve can't keep up and the excess crankcase pressure from blow-by is pushing the oil past the rings of the other cylinders.
