Regular work commutes, average speed of 39 mph, four bars of fuel left, car computer said 46.3 MPG. Skip shifting more commonly. Still using horribly flat spotted tires. Attached scangauge and monitoring how the car behaves. Ignition timing advance seems pretty aggressive compared to the V6 accord, but will drop very low at high throttle. I suspect higher octane fuel would help make the most of the high compression ratio.
