Wierd oil question

#1
Ok last weekend I got my brand new 1999 briggs 5hp running fot the first time . I noticed the side cover was leaking, so I drain the oil out and it was black what gives here any ideas ? I'm thinking maybe because the crankcase breather was not hooked up . it ran maybe for ten min tops

The engine was ran before would be my guess,black oil is from beening dirty,some oils are darker than others also.Something tells me this was not a brand new motor,with the side cover leaking.:scooter:

if the motor was brand new, it could be the rings were seating and the dark oil was because the the ring material was in the oil... did it have a metallic look to it in the light?
