Hi, Got oil and filter change at garage. Took car 1 mile home. Next day checked level and found oil very dark - black greenish film around edge - like I'd expect after 2k. Took sample and challenged garage this morning.
Told me o f was changed, and that Castrol GTX has detergents which act on the sludge. After 1 mile, this seems like deleted.
What does the panel think ? TIA. PS Car is Primera GT.

Can you tell if the filter been changed?
|
Had nissan filter. I asked what they fitted and told nissan. In fairness, it did look as if a filter had been at least turned, as the logo was not immediately visible before whereas now it is.
Perhaps I'm being pig headed, and that I should have had an engine flush.
I dont want to run the car for another 10k if the oil is so dirty after 1 mile - somethings just not right !!!

Even if the engine was very dirty it is unlikely that the sludge would be dislodged after just a few miles. It would take a lot more driving than that. I would expect fresh oil to be translucent.

You wouldn't get one of those unless you asked. It's not usually part of the makers service spec.

Check the sump plug, did they remove it or suck the oil out but did'nt get the pipe in far enough. I have a 100k golf and 6 k oil changes and the oil stays translucent for the first 2 k or so. However a friend of mine had his Passat 40K diesel sevice at a VW main dealer and after 60 miles checked the level, and so did I, and the oil was dirty. He took it back and was assured it had been done properly and lifted the car to show where the floor pan bolts had been removed to gain access. Questioned again and they emptied the oil and refilled it. Not dirty after 500 miles, so what was all that about. Regards Peter

People get very wound up about oil - what type/make/grade etc to use, how often and where to get it changed. But how often (these days) do you hear of an engine failing due to an oil prob?
In my wife's Jazz the fully synth oil looks like new even after 1 yr/5000 miles. In high mileage diesel Peugeot's I've had it goes pitch black straight away. In my current Merc, you can't look at the oil - there's no dipstick!

The main issue here though is garages or other service providers for that matter, not doing their job properly, and I think they did a poor job on my car. I'm paying good money and they cant do the simplest of jobs.
There is too much shoddy service around and that incldes main dealers.

next time go to national garage they ar elocated through out the uk they only charge 15quid for an oil/filter change and thats for semi symthetic oil you can watch them do it as well!
its not naff oil but genuine brand named oils i.e castrol ect
|

Yeah, National do a good job, with prices ranging from £10 to £20. For the £20 its fully synthetic BP Visco 7000 oil (which is 0W-40).

To save time and increase their already hideous margins, most main dealers are now resorting to suction pumps rather than draining the oil & ALL the sludge via the drain plug.
There is no way all the old crud will be removed by suction and hence your new oil is blackened minutes after restarting the engine.

Well this has been discussed before.
On one of the MB sites in the USA, extraction v draining was put to the test.
The sumps were removed for examination after the oil was removed.
Draining got far less crud out than is commonly believed.
IIRC the conclusion was that suction was better.
As has been often stated suction is used on boat engines and they are a bit more critical than the average car.

I fully understand the point about getting what you are paying for but not happy with the result.the most important thing is actualy the changing of the filter with the correct unit,some of the larger industrial diesels now come with a system which never changes all the oil,fitted with a top up tank it regularly takes 10% of the sump oil and puts it in the fuel tank,sump is kept to level from top up tank,saves getting rid of old oil and regular filter change keeps it clean.
not what you paid for but leaving even 20% old oil in doesnt mean your car will grind to a halt ,I have always found that you had to give an engine serious abuse for it not to outlast the body .

In my view all that you're paying for at a main dealer is the main dealer service stamp. I'd actually rather they left the vehicle alone (and I'm convinced that's happened to me in the past).

I can't see them changing the oil filter and leaving the old oil in - it would be taking cost-cutting to the extreme!
