Dirty gritty drained oil when I did the oil change today

SoCal 370Z

You more I read this thread—the more I cringe. Your dealership was personally notified of the issue while you were there, and they want you to take an oil sample? I say to take it back to your dealership and have them assess the situation. Why? Nothing worse than an engine seizure/failure (they never happen when and where it is convenient), and why subject yourself, passenger, and other drivers to what might potentially become a life/safety issue? Take your receipts for the oil and oil filter you purchased along with the date and mileage you changed your oil; take along the photographs you have posted here for further evidence. Why the dealership did not request that they examine the car versus having you take an oil sample is beyond common sense. Find another dealership if necessary. Way the hell too much second-guessing going on here...it's not healthy for you or your Z.

Why I NEVER say NO to the Panda Lou Fusz!!!

True, SoCal, true; time's crucial in situations such as this one.

j.arnaldo

Guess so. Down here, where they distribute AMWAY, you can also get Amsoil products.
Weird...Corporate strategy??

The dealer never requested that I do an independent oil analysis. I went to the dealer (2 weeks ago....a few days after the oil change) to have my rear hatch lift springs replaced. While I was there, I expressed my concern for what I saw during my oil change. They said that they have never heard of such a thing. They asked if I used the right oil (one containing ester). I said, "Yes, RedLine." They also asked if still had the old oil. I said, "Yes, but it's contaminated with my wife's." Then they suggested that when I do the next oil change, to bring in the drained oil OR have them do it so they can witness it first-hand.

But I'll admit, they did seem to push me away....like they didn't express any concern over it and didn't want to be bothered by it. They probably thought that I was exaggerating or something.

So my plan of action is to do the analysis (hopefully, something will show), show the dealer the results, the receipts, and the pictures. This way they won't be able to turn me away and ignore the fact that something is wrong because I'll have solid evidence.

It almost seemed like the dealership won't spend time looking into something unless an appointment is made. That's the vibe that I got, which I don't blame them.

its not that they dont believe you its that they cannot get anything done without having an analysis done or if they are there to experience it first hand and take pictures and what not for nissan. Until they experience it nothing can be done unfortunately this is how it works

dlmartin81

^^ Exactly. At that time, there would have been little to no evidence in the oil because it was only a few days old. I doubt they would have taken the engine apart to investigate something that they didn't have enough evidence of.

That's why I'm going about this the way I am.

I finally received the BS testing kit today. I must say, I was pretty impressed with the packaging. BS didn't waist any extra materials, such as a cardboard box with padding and so on. Everything was packed very tight and neat. Basically, everything came in side the black plastic container, that was also wrapped in a form-fitting cardboard cylinder (not shown in the pics).

I probably won't be able to get a sample till this weekend, due to time constraints. Plus, it's supposed to rain all week and I don't have a garage.


SoCal 370Z gettin some free exposure...hehe.

fill-out form
next oil analysis reminder windshield sticker
clear (somewhat) plastic oil sample container
oil absorbent cloth (incase of a spill during shipment)
ziplock bag
black plastic shipping container

I finally reached over 1K miles with the new oil this past week and to managed to get a sample for testing. FYI, BlackStone required that the oil should have at least 1K prior to sending it for testing. So that's what I did. Plus, unlike recent weekends this weekend's weather was great, so I took advantage of it and got under the car and snagged some oil.

The oil wasn't as bad as when I did my last change but the oil isn't as old. However, there still seems to be some evidence of copper fragments in it. Take a look at the pic below. If you look closely, you can see little sparkles. I believe those are copper fragments.

Also, what you're looking at is the lid of the oil sample container. I managed to shake it up a bit in the container to get fragments floating around and inspect them in the lid.

I plan to send the oil sample to BS either tomorrow (Mon) or Tuesday. I'll keep ya'll posted.

How was the color/texture this time? Did it come out looking like half-spoiled chocolate milk again? Or was it more normal? It looks more normal from your pic, but it's hard to tell for sure.

The color/texture was much better this time around; however, the oil was no where near as old as when I did the change a month ago. There wasn't enough time accumulate as much debris and oil wear.

I called BS this morning because I had some questions regarding some of the fields to fill out on the submission form. While I had the rep on the phone, I explained to him my situation. He said that from what I explained, this sort of thing is normal to see on new cars. He said that during the manufacturing process, they can't get the copper/brass components as smooth as the metal ones. It's just the nature of the beast. So because they're a little more rougher than the metals, it is expected to see more of copper shavings than any other metal or alloy during break-in, as they're getting smoothed out. I guess my engine has some really rough copper/brass components.

But if there really is something alarming, it'll come up in the report. I told the rep that I'll be sending them the pics from the last oil change to go along with the sample to help explain my concern. For now, it seems like I shouldn't be too worried.

However, the car does drive weird at random spots on through the RPM range. It's very unresponsive at times. I hear the engine's response to the throttle input but the car itself shows no response for a second or two. It kind of bogs down. Perhaps it's fuel starvation that I'm experiencing. I thought it was a result of my internals.

What rpm range? The car is ridiculously lethargic below 3k (no torque). If you gas it up at low rpms it just won't go.

^ Yeah, it mainly seems to be at below or around 3K RPM. I'm aware of the low TQ below 3K but man it just feels odd. Like, my old 00' Civic SI seemed to have better responsiveness in that range.

dlmartin81

Actually, sometimes the pick-up is sketchy. Sometimes it's not a sudden burst of power that kicks in once you get past 3K. It feels indecisive for the first second when I get on it. But that's not all the time.

Do you (or anyone else) experience this as well?
