the green tint is not coolant--coolant in oil would be noticed on the dip-stick not as a green tint but as a green and white substance floating on the oil. The green tint is most likely condensation that has mildewed. These engines need to be warmed up whenever they are started--they are not made for short trips to the grocery store.

 

Start using Delo 400 if you run a powerstroke. Running shell in an HEUI fuel system engine is not good for it nor do you get a long drain interval. Run the Delo 400 and you can extend your drain interval another 500 - 1000 miles.

 

And the Lab says.......


Blackstone says the oil sample looked as it should and all numbers were at or below the universal average except
Nickel My count 1 Avg 0
Calcium My count 3649 Avg 3095

Fuel <0.5 Should Be <2.0
Antifreeze and water were 0.0 yippeee

Nothing about the actual green tinge but obviously not a problem.

So where did the Nickel come from and is the Calcium level too high and what do I need to do to bring it down?

Thanks for all the responses

John

 

Good news jharvey3.
I'd make guesses about your calcium and your nickel levels, but I hate being wrong. Check out the site I've attached- When they return my tests they include an explanation for every single element on the test. I'd send a sample to them because they can compare your sample to samples of the same engine & oil combination.

Mykro:
Thanks for the Rotella link.

As for the other Delo / Rotella post above- I am not aware of any evidence of the claims made in that post. International and Ford both approved Rotella. Moreover, even Chevron (Delo) does not claim a longer change interval. I am uncertain where the suggestion of a longer (non-synthetic) interval originates.

I see a lot of high-mileage Rotella trucks and I have never heard of injector issues related to that oil.

I would be interested in some facts though...

FarmerPhilCo: send along some facts - this is an interesting claim.

-Mike

 

Mykro:
I did send an e-mail off to the Shell folks and they said it's not normal.

FarmerPhilCo:
Please shoot us some facts on that statement, I'm always learning and am interested in this.

mschultz:
Thanks for the link, Blackstone has what I was looking for on their website and also sent a hard copy in the mail with explanations.
Calcium: Detergent/dispersant additive Now I'm wondering if this is the cause of the "Green Tinge", probably not but I'm not going to worry about it.

Thanks for all the great info folks

I suppose you would like me to define the acronym that I used?

HEUI: Hydraulically actuated Electronic Fuel Injection system. Your fuel injectors do not use a mechanical fuel pump with a cam and plungers to force fuel through the injector and into the cylinder. The injector has a solinoid, and oil passage, and a fuel passage with corrosponding passages through the head itself. When the flywheel, crank, and cam sensor agree they tell the computer to tell the injector solinoid to actuate and it proceeds to stop the flow of oil and redirects it down, which in turn forces the fuel to exit the injector and into the cylinder; the oil then flows into its normal passage and repeats.

The reason not to Shell is not really that it can hurt your engine but that it breaks down to soon compared to Delo 400. The oil needs to be good for it to fire the injector efficiently. You save money in the long run by increasing your drain interval.

Secondly, I will address the mildew in the oil. Mildew will accumulate in any place that will allow it. A bathroom, sauna, pool area, under a kitchen sink, standing water, etc., and you get the point. These engines are very cold compared to any gasoline engine. Because of this the engines need to be warmed whenever they are run. They are not made to just start up, go to the store and come back. When they are not warmed they produce condensation in the crankcase which then turns into mildew.

I will be glad to assist anyone, feel free to ask. I am young but I have many years of heavy duty diesel experience, and a dt444e putting out 789 ft/lbs.

 

PhilCo
I wonder if you could assist me and I am feeling free to ask: Did you make up "flywheel sensor" agreeing with "crank sensor" yourself? Do they have to agree? What happens if they have an argument? Is this in case they suddenly decide to rotate at different RPMs or in different directions? Or is it possible that you are covering for the fact they you have no data to back up the Rotella statement?

If you can point to some tests which demonstrate that Rotella "breaks down to soon compared to Delo 400" we would love to see them. Otherwise, it might be a good idea not to make libelous statements.

Dear sir:

I was defining the way a HEUI fuel system works in such a way that a person who has no knowledge of how a diesel engine or a diesel engine with a particular fuel system works, would be able to understand with as much ease as possible. I felt that "agree," was the best word to use. You state, "it might be a good idea not to make libelous statements." Your questions that you loaded to make me seem incompetent and unknowledgable are libelous in nature. My using the word "agree" and my statements about how a HEUI fuel system work have nothing directly to do with the "possibility that I are covering for the fact they you have no data to back up the Rotella statement?"

I have nothing against Shell heavy duty oil, I prefer it over any other in heavy-duty off-road, low ground speed applications. Mostly because these types of engines use mechanical fuel injection systems (would you like me to e-mail you my definition of this type of system before I post it?) and their performance is not compromised by the inherent foaming chracteristics of shell.

I assume that you have some formal understanding about engine mechanics from your previous posts. So in the future, make sure the arguement passes the respect test, and don't ask questions that a person without any mechanical knowledge can see is not relevant with the arguement and are not even valid questions.

I say all this without offense if at all possible.

thank you

I appologize for saying that shell "breaks down" to soon. I meant that it has faoming chracteristics that present themselves sooner than do the foaming chracteristics of Delo 400 or if you really love shell spend the extra money and get the synthetic and you have an oil that is better than the Delo.

Also Mike, if your crank and flywheel sensors are revolving in different directions and at different rpms, you have a lot more to worry about than what type of oil you are using in your engine!

 

PhilCo
Good thing I brought it up then! What should I do to fix this problem? Can my dealer make the "flywheel sensor" agree with the "crank sensor" like you said it should? And will it be covered by warrenty?

-Mike

 

PhilCo:
re "faoming"

I mix a gas, a scoop of nutella (melted) and a handful of sand with my engine oil to keep if from foaming. Sometimes you have to add extra sand because the oil filter gets in the way. I have heard that if you do this on a full moon, you don't have to change our oil again for 3 years, regardless of whether or not your flywheel counter-rotates.

-Mike

 

I think that your flywheel and crank sensors need couples therapy.

it is hard to reason with the uneducated.

 

PhilCo:
Yeah, that must be it; You are better eduacated than I am.
Does this mean that in addition to non-existing sensors "agreeing" with other sensors, you made up the "foaming characteristics" bit as well?

I'd better get to bed, the short bus arrives early.

-Mike

 

ENOUGH! Thanks to everyone for their input, ideas, suggestions, and curiosity. Mike and FarmerPhilCO if you two wish to partake in a school yard brawl please feel free to start your own thread. I really do appreciate all the input but do not wish to see this thread turn into a dog fight.

Once again thanks to everyone

Happy Dieseling

John

 

dear mike:

If the flywheel sensor is "imaginatory" please explain how the tachometer works.

If the crank sensor is imaginatory, please explain how the comp gets the information to regulate fuel.

If they do not exist please inform me as to how I will go about working on computer controlled diesels, have i been living a lie for all these years? I guess that I thought that an electronic diesel used a mechanically controlled fuel system.
