Link #1 does not contain the words "Phosphorus" or "ZDDP"
Despite containing alot of references to phosphorous and a very complete scientific description of the chemical process involved, nowhere in Section 3.2.2 Deactivation by
poisoning, does it propose a mechanism by which the alleged poisioning agent (phosphorous) gets into the cat. It just says they are there, referencing studies from the mid 80's and early 90's.
3rd, a snippet from a Powerpoint presentation (pictures, oooohh, scary!):
"OIL POISONING CHARACTERISTICS
• SAE Paper 852099 - “..0.4 wt% phosphorus on ..catalyst is enough to cause a sig. loss in activity……No xtalline zinc phosphorus compounds were detected by XRD.
• SEM Images Show Layer of Deposits
• This Type of Controversy still exists today. The actual mechanism(s) of catalyst poisoning are not well known"
Am I reading that right? NO XTALLINE ZINC PHOSPHOROUS COMPOUNDS WERE FOUND?
4th linky entitled "Lubricant Basestock and Additive Effects on Diesel Engine
Title of this thread "Diesel oil in an old Musclecar"
At document 5 we arrive to find things like:
"More specifically and importantly, it seems apparent that engine oil formulation can be tailored to control phosphorus volatility."
"These dissimilar results raise further questions regarding the nature of the chemical composition of the phosphorus additives as well as effects of the other additives in the two oils"
"Moreover, the work clearly shows that engine oil formulation is a critical aspect of controlling phosphorus volatility and raises the question of whether certain additives are more effective than others or whether some of the other additives actually enhance phosphorus volatility"
Why there's absolute PROOF
that some oil MIGHT
damage a cat (if enough gets in there somehow), and so of course all those MUSCLECARS with CATALYTIC CONVERTERS
should beware of these type oils, if there was any possible way in G0d's green earth to actually identify exatly which oils they are. Is that what we're saying here 427Z06?
And of course, last but not least least, Cindy and Suzanne's FOCAS. I wonder how much the taxpayers ponied up for this one:
Document does not contain the words "Phosphorus" or "ZDDP"
Wow, the relevancy to this thread is just astounding. More relevant I think to the ongoing de-bunking of the great 427Z06.
