My Prius is 2012.. My gas
My Prius is 2012.. My gas mileage went down from 46 mpg avg to 39 mpg after a prob where my car shut down and a factory warranty repair was done. I was told that should not have had an effect on gas mileage .. The car also started using oil with that repair .. I'm wondering if the adjustment in the repair would have caused the motor to be used more and burning oil more.. ? It seems that incidence did something ? I'm not very impressed with local Toyota service departments within 60 miles of me..
