The table above is no longer accurate.
Guess who makes the Comp cams break in lube? ZDDP was invented by Lubrizol in 1940. Lubrizol is the company that blends 100% of the Joe Gibbs Driven oils. They also are the sole provider for lubricants to the US Military. This post has been edited by Jake Raby: May 20 2015, 09:29 PM |

QUOTE(Jake Raby @ May 20 2015, 09:28 PM)  The table above is no longer accurate. Paper at Cornell Univ says Submitted on 23 Feb 2015. They used Nuclear Magnetic Resonance & Neutron Activation Analysis (IMG:style_emoticons/default/aktion035.gif) (Cant get much nerdier than that). They even confirm what Jake says about recent changes in recipes "There have been concerns among some automotive enthusiasts that the lowered ZDDP concentrations may have detrimental effects on engines. Specifically, there has been much discussion concerning the effects on engines with "flat-tappet" cam shafts and high-pressure valve springs in classic cars " Truth is that I would use the Joe Gibbs if I didnt plan on changing the oil about every other month (every couple of race weekends). At 8 qts that would be expensive... My breakin-oil was Jakes, and the test & tune & first few track days was snake oil. Then I used up a case of Brad Penn, and now to the VR1. I probably havent even put 500 miles on it yet, so oil analysis would be questionable with that many changes. I would love to hear what Jake thinks about the VR1 synthetic versus the Dino version...(pictures above). |
