[QUOTE="SDMF, post: 378166, member: 412"] Broken record here but, short trips and low engine/EGT’s (Exhaust Gas Temps) are a killer to anything diesel since ‘07 when DPF’s (Diesel Particulate Filter) were mandated. For someone who lives 20Mi+ out of town and can get the engine up to full operating temp they’re likely to have no issues. Someone who drives in town for weeks at a time without a 20-30Min uninterrupted highway speed drive, the thing will eventually plug from the DPF forward. DPF’s catch all the black soot you used to see from a diesel exhaust pipe. As they catch enough soot the exhaust pressure builds and they tell the computer to increase the EGT’s in order to incinerate the soot. They can’t do the increases EGT’s until your engine is @ full operating temp and that takes 20-30Min of uninterrupted driving @ 50MPH+ IME. The smaller motors might get there more quickly, my experience regarding time to full temp is with 6.0 and 6.7L Fords. Let your DPF fill up without proper and frequent regenerations (incineration cycles) and you start to have problems w/egr valves and variable vanes on the turbo gumming up. I consider DEF to be a non-issue. It’s readily available, you just add it when you need it if for some reason you need it prior to an oil change. I only ever fill mine myself when Im going on a long trip, other than that, fill it up with an oil change and you’re good. They’ve got the tank heaters and def exhaust injection algorithms matched up pretty well for cold driving. [/QUOTE]
