What are my options there. DEF gauge reads about 1/2 right now. I take it out once every 3-4 weeks just to keep the batteries up, etc. Really won’t be using it much til late April or early May.If your truck is towing 67% of the time, it should theoretically always have a DPF with little or no soot in it. Towing generates substantially more load on the engine and therefore increases the EGT’s. This burns the soot out of the DPF through passive regeneration, and at a much faster pace than driving around unloaded. Sounds like your truck is operating as intended. I would be more concerned with the DEF’s shelf life expiring in the tank. With so little use.
