Question about FUEL

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.

What would happen if they didnt run the low sulfur?

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.

Yeap ulsd is only required for the LMMs. I wonder if canadian trucks have different emmisions stuff than the US trucks?
