I was hearing on a cummins forum, pickup truck ram, that the emission controls on the newer, last 5ish years, was cutting the life on trucks. In the ole days the class 8 engine would go 1 plus million miles on the original engine for the most part..
its said the soot and carbon is forced back into the cylinders builds up, saturates the oil and acts like very fine sandpaper wearing down components a lot faster. Stuff smaller than the oil filter can remove in many cases.
Now they are only good for like 5-600,000 miles before they need rebuilding..
let me know what you are seeing and hearing ,, is this true or just myth..
How many miles will the newer emission equipped engines go?

The newer trucks I’ve driven tend to go about 350-450 before something really expensive breaks. But they’re usually still under warranty.

ive seen several 2012+ macks (mp7) go 1 million+ miles. some required a lot of attention to the dpf systems and some didn't need much of anything. i had a good one that was rarely out of service up to 900k when i got a new one.
