Was asked when I bought my BX1880 if I wanted a block heater installed. I turned it down. Used to own my own rig and never plugged it in but used the additive to keep from gelling up. That was late 90’s. Don’t know anything about the diesel engine these days. Was that a mistake to turn down getting the block heater? It will be garaged at all times and plan on using the additives. Thanks.
