Fuel dilution can be caused by excessive active or automatic regens or cause excessive soot load based regens.
Photo of DPF soot load just before what dealer said was a passive regen, next photo shows DPF at zero after said passive regen, next one show the auto regen message. I was told the DPF will regen between 12-15%, another reason I was surprised it had a regen with such low soot load as I'm almost 100% sure I had seen soot load at a higher level before a regen, but then the dealer is always right and we owners know nothingActive regen is activated by one of two things.
Time, at most 24 hours since the last active regen complete.
Soot loading, which is indicated by ~45% on the EVIC DPF gauge.
I wish you could get the dealer to understand that, some days I think I'm talking to a cement wallFuel dilution can be caused by excessive active or automatic regens or cause excessive soot load based regens.

I think 1 thing to clarify for you here - passive regen is occurs when the motor is working hard enough to build enough heat to burn off soot in the DPF, mainly when towing or running over 75 mph on the freeway. This does not introduce additional fuel into the system to create the heat needed to burn off soot, and is a good/healthy way to keep the truck clean. The truck doesn't go into "passive regen" mode, it just burns off passively as you drive because the exhaust temps are hot.So it should do its regen at 45% soot load or 24 hrs, okay I can understand that as you don't want it packed, but mine did a passive regen around 12-15% then I will assume the next regen 15 miles later was a 24 hr regen, but if mine is doing regens at 12-15 that the dealer claims is completely normal regen timing then early regens may be part of the reason I had 4.7% fuel in the oil in 4743 miles and see oil growth again on my dip stick after truck sitting 90 minutes with the dip stick pulled out 6 inched during wait time ( at the time it had about 1300 miles on the oil), of course was told by dealer nothing to worry about or be concerned, its a real small amount of oil growth
This truck has not seen 75 mph since last September, it might see 65 if its lucky, right now it packing about 2k load in the bed, longest hwy time is 18-20 miles once a week... As for passive regens your giving me more info about them then the dealer who tell me passive also dumps fuel in the exhaust to burn the soot, god I wish they would send them to school to learn about this or give them a cheat sheet with answers to common questions...I think 1 thing to clarify for you here - passive regen is occurs when the motor is working hard enough to build enough heat to burn off soot in the DPF, mainly when towing or running over 75 mph on the freeway.

Active regen is where the truck is adding additional fuel into the system to create the heat needed to burn off soot in the DPF, this occurs when you hit ~45% on the EVIC gauge or 24 hours of engine run time.
The problem you are having with the dealer is not uncommon. They usually are very knowledgeable or know nothing about them. And some couldn’t care less.This truck has not seen 75 mph since last September, it might see 65 if its lucky, right now it packing about 2k load in the bed, longest hwy time is 18-20 miles once a week...

A BIG Thank you for all of your help.
Ya no worries. Frustrating that the dealer doesnt understand the difference between passive and active regen. 2k in the bed running on the highway for that time could generate enough heat to start burning soot.This truck has not seen 75 mph since last September, it might see 65 if its lucky, right now it packing about 2k load in the bed, longest hwy time is 18-20 miles once a week...

The reason for weight in bed was to put a stop to you need to work it harder/tow more, I found out the trailer I tow now and then because does not have electric brakes it does not count as tow miles so out of the 11k on the truck it only shows 13.x tow miles all from my old box trailer...Ya no worries.

Well it did get the service person to shut there trap some what after maxing out payload, I said it can't be hooked to trailer with electric brakes 24/7 and right now its at max pay load so what more can I do its winter time and I don't recall being told or signing paperwork before I bought it that said one of the requirements was I had to hook it to a heavy trailer 24/7/365 or I would have DPF/regen, oil growth problems and or both...Unfortunately 2K in the bed isn’t much in terms of needing the engine to work harder. I’ve even drug a 2500lb landscape trailer and still had to get above 75 mph to get a good passive regen in less than 45 minutes of driving.
Lots of great threads on here discussing active and passive regen.

Why would you want to, as I understand it the hydraulic lifters are not made to be used with 15w oilAnybody ?
Hooked on phonics worked for them...Anybody ?
