If I still had it, I would put in whatever 91 octane I wish. No brand preference but since I can get Arco prices at Costco using my Visa card, I prefer to go there. But the lines get long so I often go to the 76 by my house as they have decent prices with payment via credit card.
I could put in lower octane but due to the high compression engine it won't perform as well. If I wanted to run 87 all day I'd do an engine rebuild and drop the compression down to 10.5 or so.
