Guess I should rephrase, Hawkeye was saying he'd rather start the diesel motor with warm oil, even if the truck were capable of starting on its own without the aid of a block heater. Yet we start gas motors all the time without a block heater. So if my diesel truck doesn't have one, but starts anyway, what's the difference? My personal truck is a low mileage vehicle, but our semis st work go a million plus, with no block heater.
