2001 Olds Intrigue 3,5L, 24v, V6, it is starting to burn oil about a qt / 3000m on 2001 Oldsmobile Intrigue

Is there an additive I can use to reduce the amount of oil being burned?

Marvel Mystery Oil. Try adding a quart in place of a quart of oil at your next oil change. May help free-up stuck rings.
Thanks, does Auto Zone have it?
