I would have to guess they didn't change the oil.
We have a lot of good dealers here like you stated, but they’re employees I would not trust with anything, I’ve had friends that had engines locked up at Walmart. They did not put no oil in the engine, I’ve saw them leave dipsticks laying on top of the engine with the hood closed driving down the road, I’ve seen the oil plugs left off on top of the engine.The drain plug and filter are under a swing-down shield so I can't see or get to them to mark without a lot of work, plus it's 28° here. After bringing this to their attention I'm sure they will change it this time. The oil on the dipstick before the oil change was dark, as was the sample from the last oil change, but they were after 5,000 miles. I doubt that a quart of residual oil would have darkened the 5.4 quart sump that much, but who knows.
I believe this is a reputable dealer. I have been using them for six years and have been very satisfied with their work. The place is clean as a whistle, has eight lifts, and a large window where one can observe their work. I was too busy watching my wife drool over the 2025 yellow twin turbo Z on the floor to pay attention to what they were doing. Not sure what went wrong here, but I'll have them change the oil again tomorrow, will watch through the window, and pull another sample when I get home.
My question is, did you take the car solely for the purpose of a free oil change? And this is the result? If so, is the free oil change really worth it when you have to drive 25 miles each way for subpar service?I get free oil changes from my dealer for my 2019 Altima, which has a PR25DD GDI engine. After getting the oil changed yesterday, I drove 25 miles home and checked the dipstick. To my surprise the oil appeared black, so I pumped some out through the dipstick pipe and it is super dark, looks black in the bottle but very deep red in thin film, sort of like Coca Cola. I pulled two more 8 ounce samples just to be sure everything was flushed and it is just as dark. Even with a bright flashlight behind my sample, no light is visible through it.
I called the dealer and asked them to check with the mechanic who did the oil change to see if he may have forgotten to change the oil as I had other work done as well. The mechanic distinctly remembered changing the oil and filter, so I asked them to check their bulk tank. They sent me a photo of a sample from the bulk tank and it is golden. The dealer offered to change the oil again, which I plan to do.
The oil is a 0W-20 which they tell me is a full synthetic from Mobil, although the paperwork shows it as Nissan Genuine Oil (could be both). I did an 5,000 mile UOA on the last change at 50,000 miles, and while about 10% lighter than expected in additives and viscosity, it was still reasonably consistent with API SPs oils and the wear metals were excellent.
I know GDI engines generate some soot, but is it possible for a GDI engine to blacken the oil this much in just 25 miles of highway driving?

Good idea, I'll do that, in addition to watching the mechanic through their viewing window. I'm also going to send the black oil from this most recent change out for analysis.next time sample the dipstick oil on a paper towel before going in. Sample again afterwards perhaps. Sad to hear!
I brought the car in for rear brake pads replacement, brake fluid change, tire rotation, oil & filter change, and general routine inspection. At 74 I have pretty much hung up my wrench for dirty or unpleasant car repairs, although I still change oil & filters for our other two vehicles which have easier access. Even when just getting the oil change and tire rotation every 5,000 miles, it is not a separate trip as we frequently go to Christiansburg for other reasons and combine the trips.My question is, did you take the car solely for the purpose of a free oil change?

C- Indifference. They are busy, and if something is overlooked the customer rarely notices anyways.VOTE:
A- An honest mistake
B- Another example of another unscrupulous, dirty, thieving, lying, no good dealership service department
Pretty sure he diesnt have an IDI diesel in it.My truck makes the oil black before even starting it.
I’m kinda leaning towards this myself. The tech distinctly remembers changing the oil on one random Altima at a dealership seeing who knows how many daily. Come on now.C- Indifference. They are busy, and if something is overlooked the customer rarely notices anyways.
OH. Great idea!Good idea, I'll do that, in addition to watching the mechanic through their viewing window. I'm also going to send the black oil from this most recent change out for analysis.
