FWIW: Brenda (Wife on ST3s) and I ('04 ST4s and now MTS) have for over 10 years often stopped for gas on trips "out west" where there was one and only one choice to get fuel for many miles around; to find that the singular gas pump had only "regular" 87-88 octane. We filled 'em up and took off for another 150 miles or so of wide open spaces at a "fast touring" pace. I cannot say that either of us ever experienced any significant issues with any of our Ducs using such fuel. That said, when I do have a choice I always choose the highest octane rating available (although sometimes I do wonder why).
