E10 94 octane vs. Shell V-Power 91 octane ethanol-free

I would go with the highest octane you can get, ethanol is not a big concern to me. I don't notice a huge difference between 91 and 93 octane gas

I would go with the highest octane you can get, ethanol is not a big concern to me. I don't notice a huge difference between 91 and 93 octane gas in the Z, but when I had my Saab that was putting out 310whp, using 93 octane was a big big difference compared to 91. The improvements are basically what you noted for your Subie, turbo cars like ethanol anyway.
