Block Heaters: Such Thing As 'Too Long'?

[RadarRider]

It's getting pretty cold around here in RI. I've plugged the IDI in everynight religioulsy & since yesterday, I've just been leaving plugged it in & using the ol lady's Mustang daily. My '01 doesn't have a block heater but doesn't really have cold starting problems, so I don't know if there is a such thing as leaving your rig plugged in for too long. I'm sure this is probably a stupid question, but.....

I believe Ford says not to ever have it plugged in longer than 4 hours. Don't quote me on that 100%, but someone will come along who knows for sure.

It takes at least 4 to completly warm the block or oil system. It will be fine. I plug mine in for 8-10 hours. The only thing it hurts is your electric bill.

Yeah i leave mine plugged in for 8-10 hours also.
How bad is it on your Electric Bill?

I have left mine plugged in for a week, and on a timer, so that its actually only warming it for 12 hours. And my bill wasnt that much more. so, it cant be much. all depends on the amps it pulls.

well the heater draws 1000 watts so figure 10 hours @ 1000 watts is 10 kilowatts. whatever you get charged per kilowatt is what it would be for the day. could be around $30 to $40 bucks more a month.

I can't give you any advice about your block heater but if you see a guy up there in RI in a black '06 Duramax with a fifth-wheel plate an Oklahoma tags, smoke him for me. A buddy of mine is working up there.
Sorry for the !!
