Probably a combination of both fuel and soot...and diluting oil with fuel isn't ideal either IMO. I'm just suggesting people do their research about EGR and DPF systems BEFORE they buy a modern diesel and then decide if they are willing to deal with the "side effects" or annoyances of modern diesels. I've been there, got the shirt, will not go back until engineers come up with something better.That extra liter was probably fuel. I own a 2014 diesel and have owned numerous others. The egr is bad, but its kinda overstated.
The new Wrangler is supposed to be lighter and smaller, so I'd worry about stuffing an engine with 400+ ft-lb of torque between the frame rails.
I hope all of you who are excited about a Diesel engine in the Wrangler have done your research about the BS emissions equipment on modern diesels...on the pickups there is an EGR system and DPF system. Both are ridiculous systems and I can't believe that engineers couldn't come up with something better to meet emissions. EGR(exhaust gas recirculation) shoves dirty soot laden exhaust back into your engines intake and DPF(diesel particulate filter) is cleaned out by using some of your diesel fuel...wasted instead of used to actually run the engine. When I used to own a 2012 cummins pickup and I changed the oil, I always ended up with an extra liter of oil coming out...tells you just how much soot ended up suspended in the oil. Brutal systems, and I won't own another diesel until they come up with something better for emissions.

The Feds require low sulpher, and all the other equipment to save us all from the bad ol' diesels.
As much as the EPA's rules seem overly restrictive, everyone needs to remember what happens when you don't have them.

Do you honestly want to live somewhere without strict emissions laws?

I agree....but the approach the EPA/CARB uses is not the most business friendly....and a lot of time there is no concern for the consequences of their actions. When your intent is to make laws so restrictive that the ultimate goal is to put diesel out of business that is not a healthy business environment....like I said above I have been in meetings with both EPA and CARB officials who are amazed that we keep meeting and exceeding to them their unattainable rules an laws....When CAT left the on road market...there was a lot of cheering within the EPA and they felt confident that the rest would follow. CARB is particularly ruthless when it comes to diesel and you really have to question their motivation.
The downside of all this technology is you are slowly killing the independent truck driver and small business owners...they simply can't afford to replace their aging equipment....a brand new bare bones Class 8 Day Cab goes for over $90,000 dollars...Sleeper Class 8 trucks over $110,000...that is one truck...a replacement engine is over $30,000...to replace an AfterTreatment Device (ATD) on a class 8 truck is over $7,000. For manufacturers to meet the GHG17 regulations that will need to incorporate Automated Manual Transmissions (AMTs)....those are great but are significantly more than a Manual Transmission...more added cost.
AMTs allow manufacturers to maximize the sweet spot of the engine...something a well trained driver can do with a Manual Transmission...unfortunately well trained drivers are aging out of the system...being replaced by people from all walks of life looking for a job....AMTs are vital for a manufacturer to meet fuel economy or GHG regulations.
Well, everyone, don't blame the engineers too much. The Feds require low sulpher, and all the other equipment to save us all from the bad ol' diesels.
And Defenderbeam, for your earlier question on how I got to drive all these export Jeeps.
I just finished 31 years with Chrysler, all at the Arizona Proving Ground. Started in 1983 and took my retirement late last year.
Understand I still can't talk about a lot of things I was involved with.
