Totaally black, cars getting old at 10 years now. I do an oil change every 5k miles. And its been black ever time, so can only imagine is dont take long to go black after 1k miles
it dont go black on older cars if you flush engine out with a 50/50 mix of petrol and clean cheep oil during changing

Most diesel cars would be black after 1,000 miles.

Or if messing with petrol is abit too dangerous, i think you can pick up them engine flush cans from halfords for around £3. Its meant to be really good.
problem is.. you wash the coke / carbon deposits out of an old engine and it might not thank you for it..
Mine comes out spotless every time, and that's from an 80,000 mile engine. I service it roughly every 4000 miles/6 months, and I never use any oil other than Castrol GTX.
Mine only gets changed every 12 months or 18K miles.
Mind you it's only had one oil change at about 14K miles after 12 months and it looked pretty clean on the dipstick. It is fully synthetic I believe.
I don't think it is worth changing it more often.

One of the apparent problems of flushing a turbocharged car is that the loosened deposits can then flow through the turbo, which only has a relatively narrow oil feed pipe. If this gets blocked then it can starve the turbo of oil. Which would be bad.
Mine's fairly black after 1000 miles. Pretty bad at a 6000 mile change.

oo it is its the life blood of your enginepoggy said:
I agree. This is the single most important thing that keeps your car alive I think. I always change the oil and filter at half the recommended interval. I'd rather spend £50 on oil (yes it costs that much for the coop) than pay the costs associated with premature engine wear.dave said:oo it is its the life blood of your engine

Why would they recommend an amount of time which would damage the engine? I expect a car may get away with 36k but they halve it just incase.
Modern diesel engines have service intervals of 18k.....

they dont test the cars for 150k miles before relese do they? i think they just gessThe Negotiator said:
It's a cost vs benefit argument I suppose.
The engine is probably going to last several 100K miles if it is regulary serviced. An extra oil change in addition will probably reduce wear, but as the rest of the car is wearing anyway, it probably isn't worth it because you will have to start changing all manner of things.
The synthetic oil is also quite expensive and the extra 11 changes for every 6,000 on a 100,000 life would be £550.00 (£50 a time for oil/filter). Seems a lot for what is probably a small amount of engine wear protection. Synthetic oil does a lot to reduce the wear when the engine first starts up from cold, so it would probably be better to switch to fully synthetic rather than standard oil, rather than just add more changes (or change the oil type between winter & summer). The Castrol synthetic stuff is 4 times better than standard oil for lubricating from start up, it is also a longer life oil as well.
You also need to keep the car for a long period of time before you get any benefit from the extra changes.

They probably do actually. Although in a lab...
Seriously though, if you follow the correct service intervals for a scenic Dci which I assume is the same for the JTD fiat range, you only have to say hi every 18k.

They do several tests, some are enviromental room simulations, i.e low/high temperature, various road surfaces etc etc. This is then followed up by road testing in various environments, many companies use a place in Norway I believe for the cold weather stuff.
are but the recomended would be for normal driving, not 140 mph on motorway (i wont menshion no names, but its a girlThe Negotiator said:
) and be standard no chips induction kits etc 
ok guys
service intervals are set for a number of reasons
to look good for running costs
to beat the competitors
endurance testing should have been done..
modern engines with semi or fully synthetic engines are good for 20k mile oil changes
the FIRE engine has a 9k oil change interval which if u use selenia 20k is less than the recomended life of the oil
for example i just changed my oil today in the cinq - for the first time in two years - it was full synthetic
was dark but still oil and still doing its job, i changed the filter too
i didn't use a flush as i have a mocal oil cooler and it would have not totally drained out
but i usually do, even on turbos
BTW 5w/40 full syntetic on offer at halfords for £15

but they cant be same as real life driving. like going to pick up mate, stop start, pop to shop stop start, then 140 down motorway, then sit in traffic for 2 hours, then more stop starts,poggy said:
ROb, you missed off a factor; they are also set for the car and engine. No company would set a limit too high just to look good since they know in 3 years time that van may have done 90k and if it has broken by then that buyer won't consider your company again. They wouldn't ever set them too high....
Oh and I think the high service interval cars have to use synthetic.
