any oil consumption additive that even works a little?

[fiveohpatrol]

i havent noticed anything in the morning starts nor can i see anything in my rearview but i've had people tell me they've seen a decent amount of smoke when i hammer it, i also switched stangs with a friend for a little drive and i noticed it when he got on it in front of me, also i blew a head gasket a few months back and had the valve guides checked when i had the heads flattened and they are all ok, its not leaking anything, no puddles either and no oil on anything underneath the car
