• Colour of oil after a service 10 Sep 2003 (Forum)
  as jet black as the old stuff. I realise that the oil in a diesel does blacken quickly but after 15 miles ?? Could there possibly be a residual sootyness left in the engine bad enough to contaminate the new oil like this or should I be suspicious and tackle the dealer about it.

• Dirty oil after recent major service 3 Oct 2006 (Forum)

• volvo turbo diesel 17 Feb 2003 (Forum)
  Under heavy acceleration sudden puffs of black smoke. I have traced oil in the air inlet manifold- presumably being pushed up after the turbo. There is also some oil in the rocker box to turbo breather. Can I remove the breather pipe, plug it and let the rocker breather vent to air to double check that the oil is coming from the turbo and not the rocker box ??

• Toyota Yaris (1999 - 2005) - D-4D Oil consumption 29 Apr 2002 (Forum)
  Just covered 1000 eventfree miles in my Yaris and thought I had better check the oil. Apart from the fact that it was still on the full mark, I was amazed to see that it had not discoloured at all. I am sure the colour of the oil is identical to the day that it was put in. I would have thought it would have had a little bit of black in it, but, nothing.

• SEAT Altea (2004 - ) - Dodgy garage ? Has my car really been serviced ? 4 Feb 2008 (Forum)
  I am not convinced the garage has done much at all as they had it for not much longer than an hour. I popped the bonnet and had a cursory look at the oil on the dip stick. It is black, thin and dirty so I took it back to the garage to discuss. They said because it is a diesel the engine retains a large amount of dirt and as soon as the new oil circulates it picks up the remnants and changes to black.
