From what I gathered, running a capfull of 2 stroke oil per tankfull is fine and won't impact the cats at all. It's a very tiny amount of oil.

From what I've seen, running only 93 with 10% Ethanol, Shell and Valero are the only gas that doesn't squeek in my car. Also, from what I've seen in my car the squeeking has to do with how much load the HPFP is under. Coming straight off the highway cruising at low RPM (almost all DI) the pump is quiet but if I idle at a light straight off the highway the squeeks get louder as the HPFP transitions to almost no load an bypasses a lot of fuel. I almost don't think it's ethanol related however what lubricants are used in the fuel and how the HPFP return deals with it. IMHO its the "return" system from it that squeeks.
