I got the PHEV three weeks ago and since then I've basically used no gas. I figure barring a long road trip I could easily go close to a year without needing to get gas. I'm wondering if anyone is, or if I should, take any measures to prevent the gas in my tank from going stale? I've read that the Volt has some sort of automatic maintenance mode to prevent issues like this that arise from the ICE getting almost no use, but I can't find anything regarding the Clarity. Should I do nothing and just drive as normal, periodically run the vehicle in Hybrid mode, or something else? Thanks in advance for any advice.
