block heater doesnt do anything for mileage, really. you plug it in before you go to bed and leave it on overnight. it keeps the block warm so the engine takes a bit less time to heat up.

honestly, since moving back to southern ontario i havent plugged in the car as it only gets down to like -15c or so. when i lived in new brunswick (north east of maine, for the americans) it would be -30 or -35c in the winter on occasion.....THAT warranted the block heater...
