The middle row is from filling up in the US after the exchange rate.

I paid $3.389/gal, put in 8.852gal. The BP I stopped at only had 87, 89, & 93. I normally run 91. So I lived close to the border is be cheaper to pay the toll to cross over, pay for fuel, then pay the toll to cross back in.

There’s a lot of places in the US where 93 is the only premium option, and realistically, it won’t hurt anything, and could help under high boost especially if you’re tuned.

Nissan tunes the engine for 91, so weirdly it did not like the 93.

That’s... strange.

All I can think is excessive ethanol content - too high octane shouldn’t really cause problems, especially given how common 93 is in parts of the US.

That’s why whenever I cut across Canada to go from New York to Michigan I always fill up just before crossing the border

If you tune for 91, 93 is not going to cause you issues. Every car in the US that calls for premium fuel is actually tuned for 91, because that’s the best you can get in most of CA, but most of the rest of us can only get 87, 89, or 93, and running 93 does not cause issues. There might’ve been something else wrong like too much ethanol or maybe some water in the gas or something like that, but it’s not a too-high octane rating.
