Im up here in northern canada. We dont have "extra low sulphur diesel". Just regular diesel. I dont think it's a problem to run regular diesel is it. Just was wondering while i was fueling up

you will be ok...the Ultra-low sulfur diesel (15ppm)has to be used on the new LMM engine IIRC.

It would probably clog up the emissions stuff....I'm not real sure though. All I know is, the ULSD sucks. I am getting worse mileage than with winter blend diesel. Of course I haven't been on many long trips since the weather got warmer here with my truck.
