Truck "Making" Oil

[Pizzamaker991]

Hi, New member to the forum but have been reading here for a long time.
I Have a '20 2500 37,000 miles on it. I have been having an issue with the oil level constantly rising, I always get analysis done with every oil change. There has been an increasing trend of fuel dilution, with the most recent sample at 5%.

I have been to my local dealer's heavy truck center. The tech was less than helpful. Even though I gave them the oil report and pictures that I have been taking of the level on the stick he told me;
1. I'm not checking the oil correctly
2. I'm not letting it drain long enough.
3. My aftermarket air filter could be causing it.
4. These trucks are allowed to make oil.
5. These trucks don't have injector problems.
Needless to say all I heard out of his mouth are excuses why they don't want to look into the problem.

Background
This was starting to happen prior to the cp4 recall being completed. I was hoping that would fix it, but it seems to have gotten worse. The truck occasionally has a stumble at idle but not always. I noticed over the last year the re-gens have gotten much more frequent about every 200mi and 5hr of run time. Previously it would re-gen every 500-600 miles.

I believe there is an issue with an injector or a O ring, but how do I get the dealer to acknowledge a problem and perform diagnostics? Any guidance would be greatly appreciated. I'll include the pics of the level

Aftermarket Air Filter?
Is it a CAI setup or just a non MOPAR filter like WIX or other reputable manufacturer?

Go back to a stock air filter and you likely will decrease the frequency between regens, which will also decrease the fuel in the oil.

For the 19+ trucks be sure to use the 53034051AB filter.

There is a newer filter that ends in AA that shouldn’t be used on the 19+ 6.7’s per Ram.

Lots of reports of increased regen frequency with filters that aren’t the AB filter.

3-5 are correct from the tech. Also, you don’t have any issues that warranty will pay to look into. Until you set a code for regen frequency too often, or any other code, the dealership won’t be able to look at it under warranty. The oil analysis could say the motor would blow up in 5 miles and they won’t care and neither do they have to. Warranty is reactive, not preventative.

As far as 1 and 2, what are you oil checking and changing techniques?

The answer is use stock air filter period, saves lots of problems.

Any time I check oil it is on level ground sitting for a minimum 30 min.
For oil change I go for a ride to heat it up, park level, open drain, open fill cap, remove filter, fill and install new filter, let drain for 45 min until it stops dripping, close drain, refill with 11 quarts, start and run for a few minutes, let sit for 30 min, check level adjust if needed.

Don't feel bad I noticed my oil growing in my 22 at 3K, did a Blackstone UOA & got a free oil change do to wording by the Ram service writer D) test it showed 4% fuel in oil and Ram could of cared less when informed, so come August I will do another UOA should have around 9K on by then but I will be using a Cummins UOA kit as some have said Blackstone use the flash method to guess about how much fuel is in the oil so I hope by using Cummins approved lab if it shows fuel in oil I will then have to figure out what my options are...

The thing I’m having a problem understanding, is it hasn’t done this since new, it has only started in the last year, and it appears to be filling faster. Here is the recent oil report.

I just sent away another sample today so those results should be in about 2 weeks. It rose 3 quarts over 1,022 miles in 33hrs of run time. That just doesn’t seem right.

Go back to stock with the AB filter I listed above. You cannot get a better CAI than the stock setup. It will likely fix your regen issue.

Any time I check oil it is on level ground sitting for a minimum 30 min.

Try letting it sit overnight. There is still a bunch of thermal expansion after 30 minutes.

It takes 12 quarts on a change, why are you only adding 11?

See the file I attached in my first post, if I fill it with 12 at the rate it’s making oil I am severely over full in no time.

Between the filter and oil it’s $80ish every change. It’s getting stupid expensive dumping the oil every 1 to 5 thousand miles.

So I try to fill it towards the bottom of the safe area to allow extra room for this magic oil.

Go back to stock ASAP, I hope your dealer hasn't seen it yet.
They will deny any engine warranty with non stock filter setup.

It is already well past them seeing the intake, it has been installed on the truck since about a month after I drove it off the lot and it has been to the dealer for various service and the 9 different recalls. So they have already seen it.

That being said, I also don’t think any of my issues are being caused by the cai, because it has been installed the truck longer than when the oil and regen issues have been going on.

"It takes 12 quarts on a change, why are you only adding 11?"

Because he will be overfull if adding 12 quarts. He said 11 and add to correct level.

I get a lot of SHEITE for only adding 11 2/3 quarts letting mine drain overnight and checking on a level shop floor overnight I am right on 12 Quarts.

If it rose three quarts in 1k miles the dilution would be closer to 20%, not 5%. Frequent regens were a big contributing factor with the 2007-2012 trucks. I would still swap out the filter setup for the stock. You are gaining nothing using an aftermarket CAI and filter.

 

[Pizzamaker991]

I called the dealer back and spoke at length with the service manager. Explained to him in detail what is happening and when it began. I also expressed my of dissatisfaction on the part of the service dept. for not even wanting to perform any diag, just wanting to blame me and the aftermarket cai.

They had me come down to do a complimentary oil change so they can be assured it was done "properly" and told me not to add any oil to the truck (even though I never added oil between changes) and drive it for 5k miles and come back so they can check the level. Not the diag I was hoping for but it is a start. My only concern, if it's making this much oil in 1k, by 5k its gonna be puking oil out from somewhere. I guess I'll just monitor the level and if it get too high bring it back to them.

I may be comparing apples to grapefruits, but I had a '16 2500 6.7 for 4.5 years with the same cai and NEVER had an issue with oil or re-gen. What did they change between these trucks in the computer or emissions system that could explain it suddenly being a problem with the '20?

The oil change and 5K interval is a perfect thing to do and let the dealership confirm your statements.

The 19+ trucks are much more sensitive to air filters, so much so that they can’t run the new “improved” OEM filter that was released for the 6.7 and they need to keep running the AB filter.

Are you saying we should/can not use the 68517554 AA air filters? If that is correct, I have had one sitting on the shelf with no way to return do to how long I've had it...

In 19+ Cummins trucks that is correct. They are still fine for pre-19 6.7 Cummins.

If that's the case I wonder why places like KLM an others still lists that filter for the 2019+ trucks: https://klmperformance.com/products/mopar-68517554aa-2007-2022-dodge-ram-6-7l-cummins-air-filter

Most Ram dealerships still sell the AA for 19+ Cummins too, despite there being a star parts bulletin.

Wowzers what a cluster being that a local dealer is where I got the Mopar air filter number last year so as to have one on the shelf ready to use when it was time to change knowing it would not go bad....
