[Spridgets] Oil for Spridgets

[conan]

  I was just wondering...  
  Has anyone any experience with LE (Lubrication Engineers) lubricants?
  It is my understanding that ZDDP contains a heavy metal that is heavily controlled by the EPA, in the U.S., and that has a lot to do with why it's gotten so scarce in engine oils lately.
  A friend of mine, who was involved in professional road-racing in the U.S. for many years, always used Kendall GT-1 back in the '70's, but found that there were problems solved by using LE that even Kendall couldn't overcome.
  He currently has a business, in Raleigh, NC, that sells, among other things, LE products.  This flyer about one of their additives is on his website:
