How many miles will the newer emission equipped engines go?

Through the fuel system or the DEF system? Or maybe the oil system?

 

Yes it cleans the soot buildup thru the induction system as well as the ring lands on pistons.

 

Induction system, and they have a oil additive. Takes about 2 hours and a oil change. About $1400.00

Had my 2013 isx overhauled at 684k ..drinking oil .
Not long after had it deleted and the oil stays crystal clear out past 30k ...Gets brown at 50k .
That's the garbage your engine is choking on

 

Know of many DD 15 engines at well over 1mill.An old friend has 2 with 1.4mill and the other 1.7mill.

 

Our fleet is full of DD15 engines that go their entire time with us without major failures, and they are traded in at 450-500k.
