valve spring sizing is based on RPM limit of the motor . If springs are failing is because they are not being built to spec. Not that the spec is wrong.I think part of the valve spring failure (carbon build up) is due to the nursing of that throttle that we all Hybrid owners like to do. Full open throttle will help with this build up. Until Ford puts stronger valve springs and or create a setting to burn off this build up.
But ya 45 is my average MPG 9 miles each way 18 miles total a day all street no highway.
