When I read you have to run the ICE every 124 miles and you have to add gas every 6 months I thought "Who me?" Now I understand. I didn't add any gas in August and I'm only down 2 bars on the gas gauge (8.9 on SG II). Unless I go on an out-of-town trip I almost never use the ICE. I do, sometimes, charge more than once a day, over night and in the morning when the kWh are still cheap on my time-of-use rate.
