I found this "E-Book" on another care care site. I'm not sure if it has been posted here before but it sure does give an extensive amount of information. http://motor-oil-bible.com/mob-2-2-04.pdf Sorry about the "Jesus Propaganda" at the end, but its attached to the pdf. I am in no way supporting or discouraging it but just wanted to mention that it attached to some really quality oil info!!
