I am an Environmental Engineer by profession, and a Chemical Engineer by training. While I may not understand everything about diesel technology, I don't see any environmental benefit from the emissions equipment and changes to the sulfur specs in fuel. I honestly believe it is because environmental do-gooders have infected the highest levels of the EPA (until now, I really like Scott Pruitt), and their goal is to eliminate the diesel option for Americans.
Given that diesels have exploded in popularity in the emissions era and they are more common in non HD applications now, the environmental do gooders have clearly failed in their intentions.
You don't see any benefit? Do you remember how bad diesels used to smell? Not to mention the smog that was present in cities that has reduced drastically. Sure it's not as noticeable as say stopping businesses from dumping raw sewage into our rivers, but the effect is still there.
That being said.... To the OP, nice work on making the 6.4 last that long. Those are great engines that get bashed on. They did have their issues but there are still a ton running perfectly.
