I am going to try to find a 2020 if it’s reasonably priced. They sound like they don’t have the issues the older ones do or the headachesI run 10k oil changes no issues with T6. 875,000 miles over 3 engines never spit a bearing. Pre government intervention GDE. Like Hydrex EGR cooler removed and placed in the proper receptacle. I also regularly run long hours at full operating temps which evaporate moisture and fuel that get into the oil. Also I try not to run much bio.
"The 2020+ engines are not as hard on TBN, which tells me the low pressure EGR is a gamechanger." This is good to know.
