What do you guys think is the reason I only get 11mpg. I also stay off the throttle for the most part. Any input would be greatly apperceated.
You will probably have to take it out on the highway the next time your clean exhaust message comes up and let it finish a complete cycle. As for the mpg are you getting it of your display or are you figuring it out. In most cases the display is off compared to hand calculated.
