Another option would be to pull the injectors and send them off to get tested. Broken rings would cause high crankcase pressure and likely a P04DB code. S&S diesel motorsports charges around $60 per injector to test them.

Thanks for the suggestion. Do/can they also clean them if they fail or must they be replaced?

It depends they can clean or repair them to some extent but thats for them to decide. There not that bad to replace all six new cost about a grand, parts only.

Well, thanks again for the suggestion. I'm happy to have smart people that know way more than me to lean on.

I changed the oil this afternoon. I filled up with Mobil Synergy diesel and added the Amsoil injector cleaner. I should have read the instructions before I ordered the Amsoil injector cleaner because it calls for TWO bottles for clean up and one for routine maintenance.

Hopefully it is B and can be fixed with fuel additive and not a more costly situation like needing new injectors or a broken ring or something like that. I don't know what you mean when you say cylinder/injector offsets. What is that exactly?

I'm going to start a new thread about this fuel dilution thing because I think it warrants its own thread.

It should have an adaptive learning/offset PID for the various cylinders - basically, is a fuel adjustment from baseline PID.

I have edited my two sample postings to include the amount of fuel burned for the period the oil was in the truck. For those of you testing oil and posting results, if you keep track of your fuel it would be interesting to see the total fuel you burned. With our varied usage I bet we would see at least a 50% difference for a nominal 10,000 period. Anyhow, over time it might provide enough info to be of some use when comparing oil test results.

Anyhow, just a thought.

I'm going to keep track of fuel usage for the next interval and analysis per Howie's suggestion. I guess I'm thinking of how much towing I've done and the corresponding increase in fuel burn (or leak into the combustion chamber) that could result in higher fuel dilution of the oil.
For instance if my truck averaged 24 MPG without towing and go 10k mile interval it'd burn about 417 gallons and if I towed about 1/3rd of the 10k interval at an average of 14 MPG that would be an average of about 21 MPG for the 10k interval and require about 476 gallons. Around a 15% increase in fuel used for the same amount of distance.

I put 27,500 miles on my last change of Rotella T-6 and OEM filter! Blackstone says I should be good for 30,000 miles this time. Very pleased with my UOA.

Those are very impressive numbers. Are you mostly running empty on the highway?

Yes biodiesel; I commute 100 miles per day, mostly on the highway.

Dave, I assume your truck is tuned?

That's really inpressive @DavidG

 

[Fsmith246]

Well my report is bigger than your report!!!
Rotella T6 5W40 all miles. Pulled travel trailer about half the time (7000lbs). Mostly highway speeds.
Love the report.

GDE since ~75k miles.

Is that EPA approved tune or the pre-EPA tune?

First oil sample on new engine ( '22 Rebel Ecodiesel ).
I changed the oil early ( 2,700 ) "out of an abundance of paranoia" as I noted on the slip I sent in with the oil sample. First time I've done an oil sample, ever. Learned about it on this forum. Being a data geek (I'm at a data scientist at work ) I couldn't resist ! I think it's a pretty typical report from what I've read, with metals and Silicon being high as the engine wears in.
By the way, the dealer made a mess of my truck doing the oil change. I found drips on the garage floor the next day. Sheesh ! That's why I didn't do it myself - I invariably make a mess, drop something, spill some, get it running down my arm, splash it over the engine. But when I pay for it, I kind of don't expect that to happen.
Admittedly on the Rebel there's a skid plate down there which perhaps they should drop ideally, but no doubt they have no patience for that.
Anyway, there was oil all over the skid plate and it was slowly dripping off. So I brought it back and asked them to clean it up. They were suitably apologetic and took care of it, albeit they didn't offer me the next oil change on the house which would have been nice (dream on, right? )
I bought a 3 oil change bundle from Mopar. I'm thinking maybe when that's done I'll just go ahead and get a Fumoto valve fitted and then I should be able to it myself without too much disaster, especially with the oil filter being accessible from the top.

You answered 1 question thoroughly! For anyone who thinks SP is required for a 2022 - this sample proves they aren’t using it new! There’s practically no magnesium and a load of calcium - so it will not pass SP! It has to be a misprint in the manual!

As for the analysis - something is wrong! The aluminum is significantly lower than any valid Gen3 Samples we have seen. It generally is significantly higher than the copper levels - and being new, it will typically have residual machining dust as well. Blackstone is bad for under-reporting in the 30-50% range, but this looks worse - it looks like they missed significant amounts of a specific element!

In the future, consider using an ISO lab like Polaris through one of their retail partners. You should get better results - the $29.95 kit with prepaid UPS includes TBN and Gas Chromatography method Fuel Dilution!

Thanks for the tip, will try that next time. I'd want to pick from this list, is that correct ? Retail Partners

Correct. Verify what’s included with each, but OAI for sure includes GC dilution testing and runs TBN automatically.
Generally speaking - pick the best value for the $$, or most convenient option for you!
If that happens to be the OAI kit, drop me a line, I’ll be happy to be your AMSOIL dealer. If not, totally understand! I know a guy who walks to the tractor store next door and grabs a kit off the shelf! It’s a few $$ less as he bought a tractor there! And you can’t beat that convenience!

Well I really wanted to post my last oil analysis I mailed in early January but it was apparently the U.S. Post office didn't get it delivered! Dang it, now I gotta wait another year before it is time to change my oil again...

You must be doing annual oil changes.

I drain oil into a clean container and keep the used oil until the lab has sent my analysis report. I figured if a mishap happens, as in your situation, then I could send another sample.

yep, I only had 6650 miles or so since Oct 21 on this oil change... I will definitely be keeping some of that used oil next time.
BSL did respond to my email query earlier this week and said they had not received it.
I thanked them and just this morning BSL said give it another week before I give up. Tells me they may yet have it but be backlogged as others have mentioned on here. (fingers crossed)
We will see....
