Nope, just technically a waste of electricity. Someone did a shadetree study on it once and it's just like an extra appliance on in the house, like another refrigerator running overnight. When i do feel the need to plug in my truck i plug it in all night and it stays that way. (not from starting issues, just hate getting in a cold truck and arriving at my destination before it gets warm)...It only takes about 3 hours for the heater to successfully heat the area it heats.

I just use a heavy duty timer and have it come on about 4 hours before I will be starting the truck. Works well. I also put a fridge magnet on the door above the door handle to remind me it is plugged in. Embarrassing dragging that extension down the road. 
The block heater is about like having a hair dryer eunning on high. About 1500 watts.

Frank, that's funny!I was the shadetree who posted a rough formula to figure out how much your block heater is costing you. https://www.ford-trucks.com/forums/5...y-using-2.html
I performed the calculations again when I moved into my new house this year and I still think they are fairly accurate.

Look by your oil filter you should see an orange cord in that area, just follow it to the front.
