I am going to New Hamphire ice climbing for a few days and the truck (2002 F350 7.3 PSD w/ Rotella 5W-40 syn oil) will be sitting for several days (4) in possibly sub zero temps. I am worried that it will not start when I go to go home. There is NO possible place to plug it in, hence my question. If I have a battery jump pack and a power inverter, can I hook the power inverter into the battery jump pack and plug the block heater into the power inverter, just for 30 minutes or so to heat it up a bit? It is a big inverter, like 1000 watts or something like that. What other cold weather starting tips do you guys have? THANKS!

 

I'm not really for sure, but mine needs at least 2-3 hours to help on warm up, and I'm not nearly as far North as you. I don't think the 1000 watts are enough, isn't it about 1500? Maybe a little less.

 

We were just having that discussion in another thread, David. I'm going to measure mine soon, but someone else said they measured theirs at 800-900W. 30 mins will help, but with syn & good GPs, it should be okay...
