Generation 1 Chevy Volt (2011-2015)
Well it had been 319 days since my last gas station visit and my Volt prompted me with my least favorite message, Fuel Maintenance Mode. I did manage to drive 19,300 EV miles and 0.00 gas miles since my last visit back on April 23, 2014.
I guess I will be back around the end of January, 2016...
