My buddies '13 gelled up on him 4 times this winter. His truck is always plugged in at night and he always puts the correct amount of Howes or Power Service in the tank everytime he fills up. He fills up at the same station and on the nights when the wind chills got to -20 to -40* he made sure he put the additive in and filled the tank up and drove the truck for about 30-45 minuets to let all the fuel mix up before going home to shut it down for the evening. All 4 times it gelled the truck was plugged in (block heater cord was checked and its working) and would sit no longer than 10hrs max. Is this normal? My truck sat out for 2 days unplugged in -25* and started right up and didn't gel. Its really frustrating him, is there anything else he should be doing?
