My most of my drive is with in the city and less than 30 miles every day. So, my van hardly uses any gas for weeks and runs on battery. But, once in few days my pacifica hybrid automatically turns "Fuel and Oil refresh mode" on and start running on gas even though I have plenty of battery power left. Is there any way to disable this feature ? Any downside if I turn off this feature, if available? And also how the van determines to turn on this feature ? Based on when I refueled and how much gas left in the tank ?
