Can not say that the black components of the oil, are clean looking to my eye.
But as too if just whats been picked up from old oil still in system, no idea.

It is surprising that a new engine with low ks would be getting so much carbon in the oil. I would expect metal from running in and manufacture though.
gpg58, Mar 20, 7:23am
Agree, as do all i have shown oil too.

perhaps franc is correct here - I'm no personal fan of 15k service intervals the oil certainly does deteriorate after 8-10k has passed,
And as i have always changed at 8000 myself, i have not seen such dirty stuff before.
Given that diesel oil is very dirty again as soon as changed, it can be assumed that the carbon in itself does not effect the oils ability to lubricate?

I cleaned drain tray before using, and did check for debris after, no metal seen.

Some time ago it was standard practice to change the oil/filter in a new car at 1000 miles as any impurities (filings ) etc would be in the engine sump.There was "running in oil" which reconditioners used also but times and oils have changed massively from the SAE30 oils used.

I see they say good for "up to" 10,000 miles, so really at 15000kms it is getting near to the end of its recommended life(i suspect in best conditions only, not heavy duty or adverse driving conditions or style), but what effects can be seen at that stage i do not know.

I have done hundreds of oil changes over the years and find it hard to believe that is the colour of the oil after 12,000k's. Looks more like 25,000k and believe me, I have seen those ones as well.
Have you asked the garage if it looks normal to them? To me, it appears your car may have a very serious issue. Do another 1000k and check the colour again. If it doesn't look absolutely clear, I would worry. Let us know what you find.
gpg58, Mar 20, 7:58am
Agree, everyone that has seen is disgusted with it looking like that, and remembering this is after it was supposed to have been changed.
That is what i advised them i would be doing(rechecking in 1000 or so).
A mate that i used to share the costs of a carton of Mobil 1 with(used it for many years), has a 06 xtrail done 200000kms, and says it is still clean oil on dipstick after 2000+ kms since changing, and agrees his oil has never been that dirty when changing at 10,000.
A pessimist would wonder if it was actually changed, that they refilled with the dirtiest used oil they had.
tgray, Mar 20, 8:02am
Almost any petrol car should look clean after 2,000k, even using $20 Warehouse engine oil in it. Would look noticeably browner at 10,000 and getting black looking above 15,000k. That's my general experience.
gpg58, Mar 20, 8:03am
agree.
Maybe i should have it analyzed and take matters further.
Was rather depressed yesterday, hence timeout, and just agreeing with their stated camera review, wanting to just give up and place in too hard basket,
tgray, Mar 20, 8:06am
I would just keep a close eye on it from now on. There's a reason it went that colour and that reason would worry me.

You're kidding me? --Isn't that exactly the mistake Holden made with all their V6 /V8 cars a few years back? -not giving the rings time to bed in
gpg58, Mar 20, 8:12am
Starting to wonder if the mechanic that changed it (or not) was the one, or worked with or is friends with, the one i caught out last time(2013- another large local dealership)

Another thing of interest to me when changing, the filter was extremely hard to undo, and so was the drain bung(to a lesser degree), which seemed just plain wrong if recently been off, and refitted to factory spec. Ie, made me think just tightened further, so as to move any marks i may have made.

So you realise they could walk away from warranty now as you have interfered with the vehicle.
As the servicing is paid for they will only do it at the specified intervals as per the manufacturer, and its only 3000km away, so really you've got your knickers in a bunch over nothing.
mrcat1, Mar 20, 8:26am
Its normally just go in and change the setting to the correct interval, and if you asked they would have done it then they would have done the service at its required interval.
gpg58, Mar 20, 8:26am
The cars computer believed the oil needed changing, based on usage,(as well as time and km's).
We are debating if it was actually done.

Would you drive a car a further 15000kms on that oil?
mrcat1, Mar 20, 8:32am
Exactly what should of happened, reset the indicator and you keep driving, instead you've gone ahead and changed the oil and filter, how do you think they are going to view this under the warranty clause, Your a fully qualified technician and MTA member?
The next question will be what oil and filter did you use?
Were they genuine or at least meet the manufacturer's specification?
It wouldn't surprise me if they now walk from the warranty.
mrcat1, Mar 20, 8:34am
You need to drive the car and get it serviced at the correct interval, you've already said they expect you back at 15,000km for a service.
As Franc said, they will only get paid at the correct interval by the distributor.
gpg58, Mar 20, 8:35am
So you know better than the designers of the engine management system?

answered previously.
Off out now, will look in again tonight.
intrade, Mar 20, 8:35am
they cant void the warranty if you used the correct oil and filter aka oem filter and oem spec fluids. i made numerous threads about correct manufacturer spec oils.
They told him it dont needs a oil change because they want it to only just make it out of the warranty. they supposedly done it after insisting it be done by op is how i understand it.
gpg58, Mar 20, 8:37am
That is my understanding from research last time.
intrade, Mar 20, 8:39am
just keep records of it if you ever need it in court one day hopfully not but better be prepared for anything if it goes nuclear like most modern crap.
mrcat1, Mar 20, 8:39am
In your photo its clearly visible that you've damaged the oil filter getting it off, and the fact you've also done it on a metal driveway runs shivers up my back, what contamination have you put into the engine?
mrcat1, Mar 20, 8:47am
So they've reset the interval indicator and told you to drive it till 15,000km and then take it back in for its service, which is quite a reasonable request.
You've taken it upon yourself to change the oil and filter yourself on a metal driveway, damaging the oil filter trying to get it off, and who knows what else you've damaged, put who knows what oil and filter back into it.
Now if you drive down the road and there is a filter failure or comes loose, or seal issue, what's going to happen, you'll go in there grizzling about a stuffed engine and want it fixed under warranty, and what do you think they are going to say to that?
mrcat1, Mar 20, 8:50am
NO, incorrect, they've told him to take it back at the correct interval, he's taken it upon himself to change the oil and filter thinking he knows better than the manufacturer.
mrcat1, Mar 20, 8:57am
I know to work to what the manufacturer recommends or the dealership puts on the service sticker, then if something happens i can then say I did as required so its covered under warranty.

Just for your information, I do a lot of oil sampling on heavy gear, and your open jar of oil sitting on a metal driveway is a total waste of time, how much dust, water, silica or contamination has actually entered that oil while you've been shagging around taking pictures and what ever else you've been doing.
There is a proper procedure to oil sampling, and cleanliness is a major part to sampling, otherwise it doesn't give a true picture of the condition of the oil being sampled.
