CAR IS VERY POSS BURNING OIL. HAVE IT DIAG BEFORE YOU DAMAGE THE ENG
if it were burning oil wouldn't i see it or smell it....it shows no visable sigh of that and the oil was gone in a very short time....
IF ITS NOT LEAKING IT HAS TO BE BURNING IT. YOU MIGHT BE DRIVING WHILE BURNING OIL A BIT BUT NOT SMELL OR AT TIMES NOT EVEN SEE IT.
