Over-full on dipstick, oil analysis just came back bad, fuel in oil.

[amsoilman]

3 % by volume in a Diesel engine is "EXCESSIVE" and will dilute the oil, so the Viscosity is affected. When the Viscosity lowers by 2 SAE/ISO grades, the oil should be changed! Soot will not lower the Viscosity, but it will increase the Viscosity.



If I had 3% fuel dilution im my oil, I would get it out, and find out why the fuel is getting in the oil. Fuel contamination is definately going to increase wear in the engine.

I never received a warning to change my oil at 5000 miles. I chose to change rather than wait and was quite surprised to see the 4. 5% dilution. Regardless what is deemed "OK", that much fuel in the crankcase is too much for my comfort level, probably because I work as an engineer in the industry and just cringe when I see this.



I'm running 100% stock, no programmers, no deletes, etc. , but expect something to be done to improve this situation. I know there are other owners running stock that don't have this problem.



Dealer is currently chasing down a new turbo / egr system (P2262 codes continue), but wondering if previous problems leading to my DPF/Nox plugging/failure such as software rev levels contributed to this?

The oil dilution should not have anything to do with the prior problems or the P2262. It is a normal result from the regen process. 5% is a bit more than 1/2 quart, so most people are not going to notice anything out of the ordinary. The oil change indicator is still very accurate when it comes to the amount of fuel in the oil.

I have to disagree. I would like someone to show me an oil analysis that shows there is any more wear on a 6. 7 than a 5. 9. I have done many samples on 6. 7's just to prove to myself and the customer that these engines are just fine. So far I have yet to see any problems if you follow the recommendations of the manufacturer. I have only seen one truck that had an oil related failure. It had 86,000 miles and the customer had eleven oil change receipts, most from the dealer. The engine had a good buildup of sludge, and the pistons were scuffed. The customer said he had ignored the oil change light and followed the 7500 mile schedule. Chrysler paid to put a new short block in it, but advised the customer if he ignored the reminder he would have to pay for any future failures. Sounded fair to me.

 

[Dan Simmonds]

Having been in the same exact boat myself, I recently sold (!) my 6. 7 and happily replaced it with a trusty 5. 9 I located bran new as a leftover '06.



Yes, I took a hit for some $$$, but every lesson comes with a price.



Life is good once again.

 

[hwebster]

Funny, given the compression the Cummins runs at, wouldn't it be hard to get the fuel down the cylinders? I'm thinking the EGR might be a bigger conduit to the crankcase!

 

[DieselLady]

This whole conversation just amazes me. How many of us are willing to allow the dealer to just say it is normal and send us on our way. GM has had leaky injector problems with the DuraMax for years, with the crankcase filling up in the exact same way. To the point where they have doubled the warranty to 200k miles. Here they are just assuming that the oil is coming from Regen and haven't even tested, just sent you back down the road.

I for one have already done the deletes. Not for over full oil, but to stop the crap from destroying my engine. I pull my dip stick now and not only is it not over full, but it is CLEAN. Almost clear from soot. Even after 3000 miles. If this engine has a problem with holding oil this would not be the case. I put in 3 gallons, I get 3 gallons back out at each oil change. I don't know what smoke and mirrors you guys are using to determine how you get more oil out than in, but it seems to me that the emperor has no clothes, and it may be NORMAL,,,,, but it ISN'T RIGHT!

Fuel economy is a solid 2. 5 mpg higher, DOING THE MATH... and the truck runs like a new animal. Get rid of the regen, dpf and pcv. You won't regret it!

 

[Coalsmoke]

Yep, sounds like about the same way as I see it Diesel lady, but I need one more analysis done to show that Dodge can't / hasn't fixed the problem so that should I ever end up in court for doing the deletes I would have a good shot at fighting it.

As for the wear on the engine, I have not done the deletes, have the fuel in oil issue and here is the particle count from the first analysis I did. BTW, the oil lab said that my oil was down to a 30wt viscosity.

Particle count:
5u: 19,265
10u: 8,419
15u: 4,579
20u: 2,623
30u: 901
50u: 274
75u: 122
100u: 74

Good shot at fighting it, I HOPE. For me, if I get caught by the CALIF NAZI's will just have to make a big scene for the media. "Little old lady get's thrown in jail for refusing to put DPF and EGR back together. " I just hope they don't try to confiscate my truck. I may have to BITE them. I am not a tree hugger you see I am a tire hugger.

 

[Coalsmoke]

I hope to not have to fight it, I plan to keep the truck as clean burning without the DPF and EGR as possible. However, should I have to fight a ticket / fine, I will have at least built my case.

DieselLady,



Does your truck emit much smoke w/o the emissions garbage?

 

[hwebster]

HI there... Did you do the EGR too?

 

[DieselLady]

I Did the EGR DPF and PCV. and No it doesn't smoke. There is soot in the tail pipe, but even with the Juice turned up all the way I can't really get it to smoke. Even at May Madness when I dynoed it everyone commented about how it didn't smoke. These engines are really very efficient to begin with, which is why it is such a shame to choke them all up.
The EGR block is what gets you the most performance and fuel economy, to be honest. The exhaust gets you the breathability. EGR destroys the efficiency by adding extremely hot gas to the cooled air charge right before it enters the engine. There is even a butterfly valve on the intake that closes off the cooled air from the turbo when exhaust gas is added. This makes the air inert and also less dense with oxygen. So to allow it to have O2 dense air that has been cooled through the intercooler makes the engine run much more efficiently and CLEANER. well except for NOX I suppose.

 

[hwebster]

Well the delete is ordered, just waiting for it to arrive! Hopefully this will help!

 

[hwebster]

Delete Done

Well It was cold in the heated garage and took a few hours but the BADP is in. So far so good, I might be throwing some more white smoke but can't really tell cause it's too cold here - been has warm as -20c today! No Codes tho. .

I'm so sorry!!!! It was a chilly 70 degrees today. That was ABOVE ZERO.

The engine computer has absolutely no idea how much fuel is in the oil nor does the ECM take any oil samples. The change oil light is purely due to computer calculations relative to your driving habits.

Hey thanks for getting us back on subject. You are right... . My overhead came on the other day and said I needed an oil change. I just had done it 1000 miles earlier, and my oil was crystal clear. Ahhhh, I don't think so Mr computer!

 

[Austin Diesel]

I have been noticing this same issue with my 08 6. 7 .



I have had the Dealer Clean the turbo,install the new updated turbo port



the ECM Flashed ,Dealer said the EGR was sooted up also . The Check engine light came on this week then went back off after 2 days this week , I run the brake all the time .





The Oil level is climbing up the stick since my last fill. Wondering if fuel dilution is the cause have a FS2500 installed and fill with 13. 5 quarts until level is correct on the stick . Now the level is a half an inch above the full mark at 12,000 miles?



Any advise would appreciated i have another sample bottle ready for the 15,000 mile interval.



Austin Diesel

 

[hwebster]

Well 200+ Miles, no codes, not too much white smoke and that isn't the Delete issue - just friggin" Cold!



Just changed out the oil and will monitor the level for the next month or so! Shouldn't creep up much!



Didn't do the EGR, not supported on the Gen 2 Badp!

 

[Austin Diesel]

im seeing the same issue with my 08 6. 7 oil levels on stick are climbing oil sample said viscosity is low at 7,000 original miles.



fs 2500 oil bypass filter is installed also
