So I added a quart and till this day its been 4 or 5 quarts that i have put in it. But to answer u ? Yes ido the oil chang 3k
No. No smoke and it doesn't leave any puddles on the floor... I already took it to a couple of mechanics and they only did a visual but told me the same.... that it wasn't leaking nor anything... thanks.
