You guys got me so wound up now that I'm gonna make it a personal mission to have the inventor of the TUFOIL product buy a sample of ZDDP and do the comparison on it and email me with the test results. I won't post the results here cuz that might give you all the wrong impression that I'm somehow gonna try to get free advertising.___From Professor.
The Professor...Who let him off the island??? I thought Gilligan and the rest were never rescued???
Find 2 exact TR's and add TUFOIL to 1 and ZDDP to the other. Run the snot out of them and whichever one fails first, there is your answer. Oh crap, wait a minute... you have to break down the failure first...then have a metalurgist do a comparison on the steels to make sure the failing part wasnt stressed during cold forging or dull maching more then the other. Then there is hardness specs and material composites left after heattreating. Was each part cryo'd the same...the list is endless. Point is, oil additives are as debated as whos hotter, Jennifer Aniston or Angelina...take your pic. TUFOIL may be a great product, but FACT is ZDDP was already in oil for 60 years. It should not be an additive, it should still be in there. TUFOIL, Slick 50, Duralube...they are fads that change with an advertising push. It wasnt until bone density tests came around that we had the "milk mustach" commercials to push sales.
I am not a chemical eng, but I did stay at a Holiday Inn Express...LOL
I am however a REAL engineer in the world of Tooling and Forging for 18 years. I can make you 10 exact parts and each one will fail different than the other, at a different time, temp, place, rpm, load,etc.
Thanks

P.S. Why do you have to go back and edit every one of your posts??? Get it right the first time. I'm not joking, I am being serious.
