Oil in my oil burner
I had my car serviced on Thursday. It's a 2008 passat 2.0 tdi 170. 81,000 miles. My question is I went to check the oil yesterday morning and it's black in colour. Is it possible for the oil to discolour this quickly or have the garage either "forgot" to change it or simply haven't bothered. Would any remaining oil in the sump make it so black so quickly?
I have checked the air filter and this has been done so they have obviously done something to it. Thanks David

Whereabouts did you get it serviced? I am now in the trade so will see if any of my colleagues have any inside info on the garage. I wouldn't have thought it would discolour that quickly at all. Sounds like not being changed to me

Quite normal for a diesel. I was shocked when I first did an oil change on a diesel engined car, the new oil was black within minutes of running it. It's to do with the sulphur - see this:https://uk.answers.yahoo.com/questio...8030430AA9bIlR

Sulphur is yellow
 If you think about how much oil is left in the actual engine it will get dirty quite quickly,carbon is what blackens diesel engine oil. If you are ever stuck I have 6 ramps in my man cave.  The info in that link is a bit suspect "sulfur" I hope you did not get a "Pitstop". Proper cowboy outfit.
