What Octane for the FR-S?

I always use 93 I had never had issue I've done 93 for a whole year using Shell Nitrogen Gas and BP Gas. Never downgraded. What about you guys?

If there's 93 in my area I don't know where it is. I've used 91 for over 10,000 miles with no problems.

93 octane most of the time down here in FL. Used 91 octane on my trip up to Arkansas a few times and never saw any issues. Ethanol free gas is used when I want the fuel pump chirps to go away for a tank or so.

In my area, one brand has a 94 octane E10 blend. Everyone else is 91 max. In the heat of summer, the car runs noticeably better on the 94.

93 Sunoco mostly, but often other 93s. Downgrade savings don't justify the loss of power, use the best you can get.

Wish we had something other than 91 Octane here in Nova Scotia.

94 Chevron. Smells so good

I've read avoiding gas with ethanol will help avoid the chirps. I'm at 1500km and chirp free so far.
