Mileage is absolutely right northguest47. Aveo now has 149628 miles on it currently. Owned the car since new in 2004. Car has never seemed to waiver from those miles per gallon its whole life.

Great news, indeed. It might be time to check the tdc of all the cylinders, replace the plugs and wires, do a compression test point, uncork the exhaust, and then drive the car gently to see what it can achieve, mileagewise
