Here's some info from Caldwells speed shop website.





Lots of opinion there.



How do you come to the conclusion that what is stated there is opinion? They have charts from the various oil brands and additives that state the facts on those products from test laboratories. I don't believe they're making up those figures just to sell zddp.




Anybody else followup the link to "caldwellsspeedshop" ? What do they sell? I don't see anything except the oil additive. I clicked on the link at their website supposedly to the independent laboratory testing...HaHa: 404 not found.
