    I charge my plug-in at home to a full charge and drive in ECO Mode. I go approx. 25 miles on the traction battery before the ICE turns on.

    My question is, if I switch the drive mode to CHARGE Mode so that the ICE charges the HV while driving will my overall mpg decrease? Logic says that it will. I don't drive enough miles to test it in a timely manner.

    Does anyone have experience with Charge Mode?

    Charge mode will decrease your overall mpg , ICE will work harder accomplishing 2 tasks meanning propulsion of the car and charging the traction battery simultanously . Charge mode will not happen over 80% of traction battery charge level.If you need a quick charge to 80% , charge mode will get you there more rapidly
    than L1 or Level 2 charging ....
    I use it to burn aging old gas before it gets stale, mind you I use one tank per season.;)
    For my usage , when I need gas , I go for half a tank , unless I need to go for a long trip.

    Wow, one tank per season. I've been using 1 tank per 1,500 miles. I do like your 1/2 tank idea. Thanks for your insight.

    It will certainly reduce mpgs, but idk if anyone has calculated it
