Well, ACCORDing to my math, you are getting approx. 17 miles/gallon. If you are hitting the gas pedal hard, that will decrease gas mileage. If you car shifts at like 3000 rpms compared to 5500 rpms, you are obviously going to get a worse mile/gallon ratio. The rated amount is accelerating very slowly, shifting at low rpms and never smashing down the pedal.
