I am seeking advice from Ram Cummins owners that work in extreme cold temperatures - Canada and northern US states. There is the theory that a DEF tank with a high level of DEF will freeze and will be a problem. How does the team deal with this issue? A local guy here said only fill the tank to a low level and let the internal heater do its job. And a freeze and a thaw causes the DEF to deteriorate.
What are your tactics to deal with DEF in cold weather? Thanks
