Question is How much oil are you adding? 2014 was known for carbon packing and it affects the DPF system very badly.. My DPF and DOC are messed up bad from the Blow by. Cummins says something like 1 gallon every 3300 is safe but its really not.. That oil has to go somewhere which would be the DPF system. I regen everyday because of carbon packing.
Despite what cummins told you, It is a lot of people experiences that if the engine is using more than a gallon every 8,000 miles or so, the regen system will not keep up very well and has issues.
