DIY 15K Service on Q5 2.0T- Should Oil be Black?
Recently did the 15k oil change DIY using the extraction method. The first oil change was performed (presumably) at the dealer at 5K. The oil I extracted was completely black (not brown). For those that have performed 15k oil changes on Q5s, is black oil at 15k normal? I'm a little suspicious that the oil was not changed at 15k because (a) the oil filter was so tight it took a breaker bar to remove it, and (b) the oil was black (not brown as I would have expected). Thanks!

If the dealer did change the oil at 5k, it could indicate problems w/the engine itself if the oil turns black relatively quick. Did you save the black oil? You can have it tested here:

If you are DIY I would suggest doing another change at 20k and have it tested again at Blackstone.

Ganny, the oil goes dark on these (gasoline) direct injection engine very early.

Every turbo car we have had turns the oil black just about instantly after you start it. And that's with 100% synthetic oil as well.
