From what I’ve read in the past, idling is hard on a diesel due to high levels of soot build up in the crankcase, EGR cooler and DPF, but this also makes me wonder just how the oil sensor goes about measuring oil longevity?? Starting the engine occasionally for only a minute or so may be the best ticket just to ensure that the internals surfaces remain lubricated…
On a different note, now on my third Cummins I much prefer the DEF since emissions (mainly NOx) is now being treated chemically within the exhaust tract and much less so under the hood by soot producing EGR. This method results in much less soot build up in the turbo, EGR cooler, DPF and crankcase oil as opposed to the former scheme of lowering combustion temps (to reduce NOx) and increasing soot via EGR recycle…
Still not as maintenance free as my older 5.9 but a worthy improvement for sure…JMO
