Possibly burning oil? Is there blue smoke in your exhaust?

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.

I've taken it to the shop to get the oil change... but two months ago I did the oil change and Two weeks later I noticed a knocking sound so I checked the oil level and it was really low. 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
