Hello all! I have an 06 F350 with nothing done to it. I run 5w40 syn. I work a 24 hour shift and now the temps here are in the 30s or below. recently the truck started to not start Right up. I will go out and turn the key wait 2 or 3 min and try to start, it will crank and sound like it wants to start( white smoke now coming from the rear) and nothing. After about 3 to 4 times of this it starts right up and idles fine. When I'm home i plug it in and it starts right up with no issues? Just replace my batteries with Die hard platinums.
