Speaking of octane, a few years ago I sent my wife on a full-day racetrack course @ Sonoma Speedway (once Infineon) in her 2011 Porsche 911S cabriolet. We found 100 octane right outside the race track and my wife said her car has never run better, smoother, faster. I just wish I could get 93 on a regular (pun intended) basis.
Have you ever thought of moving to FLORIDA?
