Yes, I know gas mileage will vary depending on driving style. Yet I'm still wondering how many miles I can get out of my dx civic hatch. I usually fill up around 300 miles. The gas guage reads just over the red. MPG = 34-39 depending on traffic/ driving style. What are you guys getting. When the gas light goes off opprox. how many miles do you have to fill up. The gas tank is approx 10 gallons correct?
