My RX300 runs 93 octane here in Miami. I like to run Chevron or Sunoco. It's also not so picky with some of the non-branded super unleaded gasolines, but I know sometimes, for instance, my gf's expedition, ran a lot smoother after I switched her on to Chevron and she uses the 87 octane. We haven't had good experiences with Shell or BP in that V8. I personally have had some A/F sensor issues (thankfully just pending errors) pop up when I ran BP and to a lesser extent Shell in the RX.
