In this months issue of Auto Restorer in the Mechanic On duty section there is an article about oil additives and he pretty much says that they are snake oil and tells us why.

Lucas oil was founded by a truck driver and his wife not a petroleum chemists...kinda of like going to a house painter to have your kidney removed....shoemaker stick to thy lasts..?

I guess it boils down to opinions are like earwax, we all have some....?
