These are the facts from a EPA and the City of Niagara Falls Water Board study that was done in Jan 2020 because they were ordering their new fleet of trucks. I know the facts because I supplied 5 oil samples from my fleet of 9 Ram trucks with 6.7's from 2017's to 2020's to them. They wanted to go back to diesels because of the cost of engine replacements with their current gas fleet they have experienced. I have a good friend that was part of the study for both the FCA 6.7L AND 3.0L. One report they received back was oil analyses. The newly designed aftertreatment system combined with the new coated pistons and skits along with new designed piston rings has lowered fuel migration to between 0% and .02% in 17 samples with the average coming in at .0001% , You can Google and quote as many generic articles you please but they are not facts to the 3.0 EcoDiesel and should not be portrayed as facts. They are generic studies. Your whole post was Google quotes except one sentence.No offence..... but if you know how the system works, you would know that DPFs do and have been shown to cause diesel/oil dilution. To create regen condition (very very hot combustion temps), extra fuel is injected into the engine to start the regen process. 99% of vehicles in Europe do not have oil life monitors or the like, however when DPFs were introduced, I have experience with several that introduced oil service lights that were purely triggered by calculations that determined likely oil dilution levels due to the number of failed/attempted/successful 'active' regen cycles.
"A significant disadvantage associated with active regeneration is the dilution of the engine oil caused by a small amount of diesel during the post-injection cycles, where fuel is injected into the cylinder after the regular combustion. A thin layer of fuel can build up on the cylinder walls, which leads to premature engine wear, and drivers are warned to consider shorter oil service intervals.
There have been various studies into the engine oil dilution issue and the scale of the problem varies according to the make and model of the diesel car in question. Evidence suggests that the problem is worsened when the regeneration process is halted prematurely or when a car is used for short trips."
Some cars are notorious for this. Just google it.
"In modern light-duty Diesel vehicles the particulate filters in the exhaust system require periodic regeneration to prevent plugging. The regeneration procedure is a major cause of dilution of engine oil with diesel fuel. The dilution of engine oil with fuel in diesel engines is not a new issue, but with lowering emission limits it gained more attention recently. Modern light-duty diesel vehicles are equipped with diesel particulate filters (DPF) in the exhaust system accumulating the soot emissions. To prevent plugging these filters need to be regenerated periodically by adding unburned fuel into the exhaust system to burn off the soot. Many manufacturers implement in-cylinder post-injection cycles, where fuel is injected into the cylinder after the regular combustion (at the end of the power stroke and during exhaust stroke). During these late injections, a thin film of fuel can build up on the cylinder walls and be wiped by the piston into the lubrication system of the engine where it dilutes the engine oil [1,2]."
