Anybody believe in oil additives? Duralube ?, Prolong ?, Slick 50?. Good or bad for the engine ?

Snake oil, every one of the ones you cited. Stay away from the additives. Most contain PTFE (teflon), and they will clog up the engine. Stick with a good grade of 5W-20 or 5W-30 synthetic and change the oil and filter every 3K-5K as recommended.
