Block heaters are another interesting topic. Depending on ones experience. There are guys plugin them in in Texas when the temps get to sweater weather and those that don't break out the block heater til 0F.
To the OP, no need, unless you think you will have unexpected trips, to plug in for extended periods.
Put a timer on it for daily use when cold or plug it in a couple hours ahead of time.
since a block heater draws aroun 1.5KW, they can definitely add to your electric bill. at 10cents/kwh they will cost about 15cents/hr to run. Most have a thermostat to turn off when the coolant temp gets warm, they usually won't run all the time, but even if it runs 12h/day, thats a buck and a half a day, or 45 bucks/month. rather not do that. I have my duramax heater on a timer. If I do plug it in, it is set to come on about 3 hours before I need it, which is plenty of time to get it warm.
