My suspicions were actually raised after I got home immediately after the second service and seen the black oil....as my home was only 5 miles from the dealership.

Wow only just read this, amazing my oil is still golden brown and see through at 2,500 miles
and i always mark the filter before i take any car for a service so i can see if they change it!

if it was black after 5 miles i would bet its not been changed.
