People are missing my entire point, you can not compare the 5.9 cummins, or 7.3 to the newer engines, the new diesels are a completely different animal. Of course a 7.3 or 5.9 blows a gas away, thus the reason i own 2 7.3's.
The entire reason for oil sampling is to montior the amount of fuel going into the oil, as when the truck goes into regen, fuel ends up in the oil, to much, or a failing injector tells the sign it needs to be addressed. Take the 6.4 ford, very few fail because of oil, rather they fail from injectors which burn the pistons, or oil which is broken down causing rods bearings to spin.
Also the oil requirements have changed for the motors, most require 5w40, something which resists breakdown, also fuel filtration must be perfect, thus the cost of fuel filters, and the fequency of replacement.
Im going to take flack for this but the cost of the new diesel can not be understood until someone has owned one and repaired one. I just changed out one injector and 2 rocker arms on a 6.4 f350, total bill was $2500. Ford wanted close to 3100, and the truck for nearly a week. Injector was just shy of $550. Truck is on motor 3, gets about 13mpg, and just broke 140k. Now tell me how diesel is cheaper than gas.
