Oh, I generally only use Shell 91 unless I'm in a pinch. When I was up north I went to a Mobil or Chevron servo that had non-ethanol, 92 octane. When in California I have a few local Shell stations that have 91 V-Power without any dilution past regulatory standards in California.

I stay away from small places or independently owned servos that rely on just selling a lot of product because those tend to be the ones with shitty quality or use crappy octane boosters.
