I have been running regular unleaded 89 octane for the most part, with no pinging and good power. Occasionally I fill the tank with mid-grade 92 just to give a little boost. I consistantly pull 12 mpg in town, and haven't had the gumption to make a long highway run to see what the mileage would be.
