Re: CleanMPG Previews the 2012 Kia Rio 5-Door Hatch The ECO trimmed EX’s Isg is rated for 350,000 starts. Assuming you had 10 stop lights between home and work.. 350,000 starts / 20 a day= 17,500 days. Almost 48 years?? Is that right? You would be able to drive to work and get great MPG, until the year 2060?
