Took my nissan juke diesel in to the dealer for its first service.
The oil was black and thin as you would expect. Picked it up and drove 5 miles home.
Checked the oil to find it was still black and thin!!!!!!!!!!!!
Never had a diesel before, is this normal???????
-
urghh...... trickyyy. My own personal experience says that there should be a bit of an improvement in the oil colour, but invariably they go sooty almost immediately. Would like to say that if they drained it thoroughly (as most dealers etc don't, just whack the plug back in soon as it starts to slow, get them out, and the next one in, save time etc) then you'd get an improvement, but in truth probably almost imperceptible.
Basically Diesels are mucky engines. But I hope you've had an oil change! :)
-
I wouldn't expect it to be as black as soot after that short a distance.
Worth having a look around the filter? Filter should be clean externally, and I'd be surprised if there wasn't a bit of oil around it as evidence that it's been changed. Ditto the sump plug, although they may have just sucked it out through the dipstick tube.

I used to do the oil on my Astra diseasal about every 5000 miles. The new oil was black by the time I'd driven it around the block. ??? And many places do suck th eoil out these days ....... easier and no under engine panels to remove
-
Fair enough. :y Not done too many tractor oil changes, thankfully, so I have limited experience.
-
Yes, as you say, try and check for signs of disturbance. But that depends on how familiar you were with the 'looks' of it pre-oil change.
I know where the leaks and marks / stains are on my engine block, I was under there only the other week, if I climb under there today I'd recognise a new leak straight away. But that's pure happen-stance, as I was doing the gearbox oil recently. Not sure how you'd conclusively tell on a near-brand-new vehicle.
Also the sucky sucky method is used a lot now, as said. Not good, in my humble... but as every year passes mechanics become cleaner and cleaner until one day they will only know how to install and reprogramme new black boxes, engines will be sealed for life, no ability to change the oil unless you send it to a specialist.

New Oil Filter?
-
Not on a first service. Should'nt be that bad on a new diesel.
check around the filter housing and look for any spill marks around the filler neck
-
Must be the easiest and oldest trick in the book for car garages, charging for an oil change, without doing one... :(
Not saying this has happened for sure, in this instance, but it really is the easiest thing in the world to lie about.
-
Its done 14k. No sign of oil or oil spillage being wiped off either sump plug or filter area.
Filter is on the front of the engine high up. Hoses in the way. No way you could get it off without making a mess >:( >:( >:( >:(
not happy

take it back..................
-
Seconded.
-
Even if new, if the filter has done 14K in an engine bay, it will have a layer of grime on it. Run a finger over it and see if it comes off clean - assuming it's a cartridge filter, of course. :-\
-
They say the filter was booked out and 4.6 litres of oil was dispensed from the machine so it was done. end of
They also say that even with an engine flush the oil still goes black quickly.
I will do myself for peace of mind.
Filter looks dirty to me.
-
Booked out and fitted are two different things... :-X
They probably did change the oil though...
-
You should receive a questionnaire from either the dealership itself or from Nissan,basically asking if you were satisfied with various aspects.Look of dealership,helpful service reception staff,was vehicle ready on time,was it washed/hovered etc.Your responses then contribute to the dealership CSI figures which then gets[or not]them bonus money.So you can always use this to express your unease/displeasure as you see fit.
-
if they didn't do it that is properly bad!!! as taxi says, booking out parts and using them are sadly two different things.
start doing them yaself in my opinion. if its a paper element filter with a plastic housing, put a line of tippex down the side where the lid meets the body.....

Yes, if the filter was still full of crud, that would explain it blackening so fast.

Booked out and dispensed,,, then put into toolbox, for mates car on Sunday. :)
Never happens at a dealership?
-
All my tractors have turned the oil black within a few minutes. Nature of tractors. You need to look at other signs to see if filter has been replaced.
Last dealer service on my Omega they clearly didn't change the filter, and they gave up protesting when I got the service manager out to explain why the filter still had my initials and the previous change date/mileage written on it if he had changed it that date.
-
we always use engine flush this help to get as much crap out of engine as possible
but how you going to get oil from oil cooler ? or cylinder head? turbo oil pipes? oil filter housing.
you wont there always will be some oil left.

The oil on my Signum is still a golden(ish) colour some 3500 miles since the last oil and filter change.
It may be different on a proper engine...............one that runs on petrol as God intended. ::) :P

Its impossible to tell so I will do it myself :y
next time i will watch them do it!

If you start DIYing it you'll invalidate the warranty. ;)

I'm not sure that is still true, provided that you carry out the service in accordance with the manufacturers requirements. IIRC the law was changed some time ago to allow independents to service new cars. :y

Must be Vat registered and use genuine parts ;)

Ahh that's the catch. :y

However that only applies to servicing... Brakes/suspension etc is fair game... Using genuine parts and keeping the receipts... So savings to be had :y

Same for me, on my 4 most recent cars, (2 petrol 2 diseasel) it never looked like I'd changed the oil. On the 2 petrols (Saab 9-5 Aeros), the oil looked like new when it came out. Then again it had only been in there 3000 miles :D. In the 2 Diseasels (MK3 Mondeo & Rover 45), the new oil looked black as soon as the engine was ticking over >:(.
-
I've had the same blackness when changing deesal oil ... maybe this means contaminants
are still in the system and an engine flush would maybe
clear this :-\
-
I had exactly the same issue with a first service on diesel Honda Accord, that was at 14k miles.
I checked the oil a day or two later and it was black. Queried it with the garage and they assured me it had been changed. With hindsight I think they probably did change it.
Having run a couple of diesels for a few years now unless you halve the oil change intervals (which I do) you cannot see an improvement in the oil colour after a change. Even at half the intervals the oil is pretty much grey after one journey.
There's enough black oil left in the system that it colours the new oil immediately.
In terms of invalidating the warranty, when I've made warranty claims they look at the service book. So the additional services I've carried out (using genuine parts but not recorded in their book) aren't an issue. And I doubt they'd have a leg to stand on even if they were aware.
-
if its black shortly after changing say 2 engine hours then either it has not been changed or all the old oil was not removed. most likely the latter. if you go to the trouble of removing all oil from a diesel it will stay amber for a while. difficult though - on my diesel the oil cooler retains a lot of oil. alternatively flush by doing two changes. when i have done either of those the oil has stayed nice and clear for quite a few hours running at least.
common to change the oil and not bother with the filter especially when a car is being sold hence always give a new car an oil change.
