I hope I am not bringing up old questions but I am confused. What is the difference between oil ratings? Which do we look for and which do we avoid??? I have seen CI, CF etc........

Search for "ZDDP" and you will find just about every oil related thread on here! Oh, and you might want to put your reading cap on, because it has been a very much discussed topic around here
