I have an '02 F350 with 7.3 and approx. 104k miles. Unfortunately, I don't get to drive the truck daily - maybe 2-3 times per week. I'm always uncertain what nights I should plug it in because I don't know if it's going to be used the following day. Living in Pennsylvania in the winter months it can get pretty chilly at night in the winter. My truck runs / starts so much better and smoother after the block heater has been plugged in once the temps get below freezing. My question is - are there recommendations for how long you should / can leave a truck plugged in with the block heater ?
