    I'm going into my first winter with a diesel, and was wondering how cold it needs to be before you plug it in?

    I have a 2000 Excursion with a 7.3 powerstroke. I have never pluged it in,never had a problem. Keep it parked with the front end away from the wind. make sure you put additive in the fuel till your sure the fuel your buying is winterized. I would plug it in if it is below zero or if it has not been run in a few days.

    What type of diesel.

    My duramax: I plug that in under 10 degrees outside overnight
    My 6.5: I plug that in under 32 degrees outside overnight

    My 6.0 diesel starts has started fine, the issue is that it takes forever to get heat if you don't plug it in! I usually plug it in if it is down below 20*.

    My cummins has never been plugged in since I got it, my 7.3 Powerstrokes get plugged in when it gets to 15-20 degrees.

    I have a ford 6.0L that I plug in when its below 20. It is more piece of mind, when I have to start it at 4:00 am.

    I don't plug it in unless it is below freezing. Makes it easier to start with the remote starter.

    Make sure and dump some Howes in the tank.... cheap insurance. run it for a while too so that it gets in your lines and filters.

    I have a 6.5 in a 95 chevy 2500 that I never have to plug in, and I have a 444E in an International ( same as a 7.3 powerstroke) that I have to plug in if I am going to start it at all with the temps below 20 or so.

    plugging in is a little easier on the the motor, I may plug my cummins in, but I use a timer and just heat 2-3 hrs before start-up, saves on the electric bill

    Does a warm shop make it considered being plugged in? No, seriously I do it below 20 just for piece of mind. All three of the 6.0ltr powerstrokes start fine even below 0. Quality Interstate batteries are to thank for a good share of that.

    I park inside the shop.... However if I need to leave the truck outside for any reason I usually plug them in at anything 20 degrees or below. I have started them down to 0 degrees w/o plugging in but I feel it is just so much easier on them when they are warm....

    Hey all, new to the site not new to the plug or not to plug, got an '03 7.3 Stroker that is so cold blooded that any thing below 35 she goes on the hitchin' post. And I do feel it is easier on the motor anyway. So if I know I'm gonna need it I plug it in either the night before or just a couple hours before I head out. Which ever works out best.
