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

Like Dave said: don't use them. They either have no effect, or negative effects. There is no evidence that they have positive effects. Do a little internet searching (anecdotal evidence (testimonials) does not count).

Put your money into a higher quality oil and use it as it was engineered and designed: unmodified.
