I don't know if this is relevant, but my Porsche-Club group ran Mosport once and were all about to fill up on 91, which was all we could find. A local guy came by and hipped us to where we could get 93. The only guy who missed the tip filled his 944 Porsche turbo with 91 and burned a valve. He had to take it back to the states on a trailer.
