I'm a big fan of Walmart but one time I dropped my 5er in the lot and took the truck for an oil change. The next day (500 miles down the road) I checked the oil and it was blackish. I believe they didn't actually change the oil. Went to a dealer and got it done "again".
LOL must be your first diesel, blackish oil after 500 is normal. Typical oil change doesn't get all the black oil out so to be blackish after 500 miles is expected.
