This is from the manual…
Note: The heater is most effective when outdoor temperatures are below 0 °F (-18 °C).
Also, three hours is about the most you want to plug it in. In other words, plug in for three hours or 12, it’s not going to get any warmer. Put it on a timer or plug it in a few hours before you need the truck.

If it was convenient I would definitely plug it in at those temps. I use block heaters frequently and I think the benefits well outweigh the cost of operation used on a timer to run a few hours before needing to start the vehicle.

I plug in any time the temps get around 30 degrees. Not because the truck needs it but because it makes defrosting the windshield much faster. I haven't had to scrape frost for 4 years. I have it set on a timer that is set for 4 hours before I leave for work. Coolant temp is around 80 degrees on startup no matter the outside temp.
