I was looking at the msds sheets today for edge and syntec and noticed at the bottom that i contains these elements. I thought it was really weird and I wonder what use these elements could serve in an oil.

Seems odd. Are we talking in ppb incidental levels?
 
I heard it was to prevent people from downing "castrol cocktails"...

Lead can be used to form a low speed anti-wear film. It used to be used in slow speed gear lubes that had high loads but low speeds. NEO use's it in their oil and gear lubes. It is one of the things I hate about their oil is that it makes getting a good read on bearing wear almost impossable it is like when you use leaded fuel like in aviation.... It just add's to the issue of interpreting the UOA.

I do not know about the arsenic or cadmium but many heavy metals can be made to work as anti-wear agents tungsten has been tried and antimony and Conoco Phillips is advertising a titanium derived anti-wear agent so it is a possibility! We need to have Molakule chime in with this information!

Sort of like the sulfur in automotive nitrous. We had two vendors around here that sold the medical non sulfur nitrous for automotive use. I won't get into it any more detail lol.
 
These are likely trace ppb impurities in the additives or base oils. I believe California requires that any measurable quantity be listed.

I'm not surprised if California would put a sticker with nutritional information on bottles of engine oil stating "Not a Significant source of ... "

Their engine oils have to contain a lot of sugar because that Scottish guy that runs around and whips people with his dipstick is really hyper.

Speaking of NEO I noticed a lot of guys at the nascar race was using NEO lubricants. I had a pit pass that allowed me to go any where I wanted including the drivers meeting. So I got to witness a lot of stuff.

Man I bet that was a total blast! The last race I went to (in TN) we didn`t have the passes to get into the driver`s meeting. We had the pit passes though. I got to meet Carl Edwards and Jack Roush. My gf got them to sign the shirt she was wearing :^P
 
Neo makes a good product that works well just not my idea of an oil I want in my car. Sure you can get used to seeing all that lead but I would rather it not be in their int he first place. I have been exposed to enough toxic stuff and in this case less is more to me. I think heavy metals are not the thing I want in my oil and I do not want my kids or anyone that should work on my car if ever that happens to be exposed to heavymetals if they need not be.

SInce most of this nasty stuff gets stored in bones and in fat I am conifident that if I ever had liposuction done my fat would eat through that little plastic container that they to catch it. When we have so many other things we can use lead and cadnium are far done my list. I can not believe that they are the best answere tot he anti-wear question and EP agents or everyone would be useing them.
