Block heater
Should the block heater on my diesel pusher be left on during the winter months?

Diesel engines will start in very cold temperatures. The heater may make them a little easier to start, but the pay off for heaters come in fleet operations with engines that get far more use than our RV's. The savings is in longevity. A cold start is very hard on wear for pistons and liners and there have been studies that indicate a savings by having"warm" starts rather than cold.. winter in Alaska might be different.
