When is it cold enough to plug in the block heater?

At the diesel clinic I went to for Ford...They said 20 degrees...just remember anti-gel and to change your oil to 15w-30 for winter and you won't have any problems.

hell i plug ine in when it gets in the 30. i plug it in right after i get out to keep the block warm....it is great to have heat with in 2 min. it make defrosting the winshield a snap.

is it bad for the truck to plug it in when its not cold enough? It starting o get into the 30's here so i was wanting to get this figured out early.

i dont know i would not thin so. because it just helps keep every thing warm. i might help out the glow plugs

i have been doing it since 99 and it hase not shown ill effects.

I am a big fan of a block heater also... as stated, it's warm as soon as you start up, you have heat, and you're close to operating temp, not FREEZIN' COLD like the rest of the truck. If I don't plug in my trucks, I'm still waiting for the heater to warm me up when I get to work 30 mins later....
I haven't looked, I hope my new truck ('00 F350) has a block heater... I'll check when I get a chance, if not I'll be puttin' one in...

When it gets below 40 at night in Michigan. I plug mine in.

20 degrees is usually the deal, I don't think you can go wrong pluggin in anytime below freezing though, antigel and winter weight oil is a must for me here (alaska). A lot of times I won't actually plug mine in until it hits single digits though, I have a lot more than a block heater, (oil pan, transmission, battery) and the ol electric bill can get pretty high because of that.
