Please let me know if you'd like to elaborate on that brief response. I am new to diesels so any advice / help is greatly appreciated. Thanks in advance.

 

Never heard of it. Maybe it doesn't get cold enough to need it in New England? Don't know. I just spent 12 hours plowing snow yesterday, so I doubt it, but I'm sure someone can explain what it is to me. All I know is winter or summer, my mileage is exactly the same.
