Up to 10% ethanol in most pumps. My local Chevron has ethanol free 94 octane but it costs an arm and a leg. All of our vehicles run well on 87 octane with ethanol.
According to the news the U.S. is considering 15% ethanol and Canada will probably follow suite. Should be interesting when some one pumps that into a high compression engine by mistake. FI might compensate somewhat but a carb will be out of it's league.
