I have 1,600 miles on the following fixes to problems and 242K total miles. 1. New injectors and 5w-30 oil change at dealer. $1,400 2. New non-OEM cat converter. -$200 3. New EL-422 Ecopia tires (OEM). $700 4. 24 hour piston soak using SeaFoam. $150 $2,050 investment in 13 year old Prius with original traction battery is a lot but the car is running like new and delivering almost 44mpg in my normal aggressive driving style. Oil consumption is nil. I couldn't be happier. Great car, thanks Toyota.
