My CRD Liberty I leave plugged in over night, and basically whenever I know Im gonna need it, every day LOL Why not? easier on the starter, battery, fuel system, and everything likes to work better a little wormed up. I know I do.

My 91 Cummins started at -20 a few years ago as I didn't know the block heater cord had an open in it. I fixed that and it started a lot easier from there on.

Seems silly not to plug them in to me.





I don't think there is any question that an engine starts easier plugged in.

I think the question is, does it need to be plugged in continuously and I would say that in most cases the answer is no. If you leave for work at 7AM every morning, put it on a timer to come on at 5:30 and it will start the same as if it was on all night.

If it is a randomly used second vehicle, you could just put it on a timer that runs 20 min per hour which would be good in all but the coldest weather (like -40ish) or just plug it in about a 1/2 hour before you want to leave.

A 1000w heater uses a noticeable amount of power on your electric bill $$.
