I had the oil changed for only the second time at dealer the other day and I wanted to check to make sure the oil level was correct. When I pulled the dipstick out all I could see was black oil all the way to the top of the flat spot at the end of the stick. I wiped it off and tried again...same result. I did this four more times and each time it was the same. I began to think the dealer overfilled it. I let it sit for several days and checked it again and the side with the level information was covered but it was close to the middle on the other side. Unfortunately, I have not been able to duplicate that a second time. Is there a trick to this? I feel so stupid that I can't even check the oil in my truck. Thanks for any suggestions. Jeff

Make sure the truck is parked on a level surface both front to back and side to side.

Truck needs to be cold or at least sitting off for 15 or so minutes before checking.

First check on these is usually inaccurate and will show low due to the dipstick tube being o-ring sealed and trapped air getting stuck in the dipstick tube.

Pull it wipe it off with clean towel and recheck to get an accurate reading. I like to check mine first thing in the morning cold or after its been sitting for several hours.

Also as you may have seen the oil on these turns black almost immediately if your not tuned.

MAS, thanks for replying so quickly. I tried all of these suggestions. Except for that ONE time, both sides always have black oil all the way up the flat part of the dipstick. If it wasn't for that one time I'd swear that the dealer failed to drain all the old oil before filling it with clean oil and, as a result, overfilled it. After I picked it up from the dealer I drove it less than 10 miles to where I was staying and checked the oil. It was already black as coal. That's what first made me think they didn't drain all the used oil from the truck. Now it seems to read about a quart high no matter how many times I check it.

If it is overfilled (possible) the oil pressure guesser should be higher than normal at idle. I always add 11qts at change and prefer to keep it at MAX or slightly above.

Suggest posting a picture so others can see exactly to issue. If stock tuned it will be black shortly after change. Also possible tech did not allow long enough drain time and simply re-plugged and filled with 10.5.

With the "oil pressure" reading the EcoD provides from the factory, it doesn't matter how much oil is in the sump. It's a calculation not a measurement, the value is based on the programmed parameters.
Even on vehicles that have actual oil pressure gauge, unless the sump is so overfilled where the crank is foaming the oil, it's not going to effect the oil pressure.

I currently have the truck parked where it's level. I'll wait until tomorrow morning and check again. If it's still looking high should I try to drain some out or should I let it go? I've already driven it about 1,400 miles towing a 7,000 lb travel trailer home from vacation.

Well that is disappointing and the display is completely misleading? I knew was a guess but not to this extent.

Man I get two conclusions from your thread, maybe more.

First is I am guessing the dealer did NOT change the oil. BLACK oil is oil tainted with carbon from the EGR system. New oil is from clear to a slight translucent brown. Something is not right. Granted old oil residue staining the dipstick could make it look larker that fresh oil. While the dipstick off carefully and dip it back in. If it's not coming out clean as new, if the oil is new, then something is wrong.

Next you clearly show what is wrong by trying to operate an Ecodiesel in a stock form. Your EGR system is polluting your engine with soot. That is a real problem for your engine. To stop that from happening and keep your engine clean is simple. Simple as three letters.

It’s been a while Capt. but almost immediately after changing oil and starting it will be black again. (With stock tune)

Been a while for me also, like maybe 90,000 miles ago. Anyway I do remember going over 1,000 miles before noticing the soot contamination. Got the impression he was checking his oil very shortly after if not immediately after having that dealer change his oil.

If it was 1,000 or more miles later, I am wrong again as that would surely be more than enough usage to contaminate the oil with soot. If less than that the OP has a serious problem with his EGR system. At least that's what I remember.

Each time you run the dipstick in and out of the tube, you're getting oil distributed on the inside of the tube. So the next time you pull your dipstick, some of that oil might adhere to your dipstick throwing off your reading.

May sound goofy but rotate the dip stick 90 degrees so the tip will be presented to the oil at a different angle. May make for a cleaner dip.

Well, I checked the oil again after sitting in a level location all night and the result is the same. Black oil all the way up to where the dipstick changes from flat (where the readings are) to round (the rest of the way up to the pull). By now, after driving over 1,300 miles since the oil change, I would expect my oil to be black. I was surprised that it was so black after only 10 miles of driving. That, plus the fact that the crankcase is definitely overfilled, is what leads me to believe that the dealer didn't drain all the old oil out before adding 10 quarts of fresh oil. I have replied to the dealer's request for feedback and told him of my findings and theory as to what happened. I'm hoping that no damage has been done running the truck with extra oil for so many miles, and that I can get a complete oil change at my local dealer which the dealer at fault will pay for.

PapaCap, thanks for the suggestion but I already tried that. It didn't make a difference.

Captainmal, the only thing keeping me from getting the tune is my extended warranty. We paid several thousand dollars for a 5 year extended warranty and I didn't want to give them any reason not to pay out should anything serious go wrong with the truck. The moment that warranty is up is the day I'll get that tune.

Nobody ..... NOBODY....has had a warranty issue while having GDE. Even California people, who got it before there was trouble with their CARB threats, have no issues. Dealers hav no reason or even the ability to detect it. My dealers’ service advisors liked the idea after I told them I had it. Go figure.

Think your fears are unfounded and in the process, you are messing up your engine running stock.

I second what he said, I had a shady dealer trying to tell me my stuff was tuned, they were cheap and crooked and knew I'd pay before the warranty claim would and it would be top dollar.

In my experience the first pull of the dip stick is pretty accurate, in that if I'm on a level surface and the engine is cool, the level is about where I expect it to be.. in the middle of under/over. The second pull always comes out with oil covering the entire test area.

Well, today the service manager from the dealer where I got the oil changed contacted me and offered to reimburse me if I took the truck to a local shop and had the oil changed again. I took him up on his offer and all is well. Sparks, I found the same thing when I got home. As soon as I got home I checked it and it seemed low. But then I thought about it. If, when you're draining the oil and you have to wait for 15-30 minutes for all the oil to reach the drain hole, why wouldn't you have to wait the same amount of time for the oil to drain into the pan to give a good reading? So I waited a half hour and pulled the dipstick and the oil read fine. I tried to double check my findings by reinserting the dipstick and checking again but the oil was all over the stick. I'll just always check the oil after the truck has been sitting for a while and know that I'm only going to get one peek at it.

Thank you all who responded. I learned a lot.
