<VV> ZDDP & Max Lead 2000 save motor wear

[Secular]

  Hi David:

  Interesting points. On unknowingly ruining a motor, I'm convinced that 
  while ZDDP? maybe an excellent additive for the quadragenarian 
  [or older] cars, it's not quite so friendly with the newer 
  generations. Take a look at:

    "What seems to happen," Spikes says, "is that the additive 
    is designed to form a phosphate glass on these metal 
    surfaces, but some P2O5, or whatever it is, goes down 
    the tailpipe and actually forms a phosphate glass on 
    the catalyst." 

    The result is a shorter life for this expensive component, 
    says Michael McMillan, manager of lubricant chemistry 
    for Detroit based General Motors. That's why, he says, 
    automobile manufacturers have asked-or, really, required- 
    oil producers to reduce the levels of ZDDP in their products....

  I purchased a '63 Greenbrier in January, '08 for $1000. from a junkyard that had removed this abandoned vehicle from the streets of Cambridge, Mass. All it needed was a fuel pump and a new battery to start it up. It has a '63 monza motor. I had to rebuild the right side carb because of leakage due to an odd one piece needle valve with an internal blue washer which jammed shut. I changed all the fluids in the drivetrain, but was surprised to see so much foam in my oil and a hot running motor. My friend who is an aircraft mechanic told me to change the oil and add ZDDP . This stopped the foaming and oil coming thru the dip stick hole. He told me where to obtain a true tetra-ethyl lead additive in Indianna called Max Lead 2000 which when added to Hi-test gas lowered my head temps about 35 degrees F. The end result is a lively little motor w/ PG that runs cooler . I haven't checked my axle ratio but I don't go more than 50 mph. These vans weren't known
   for speed, but could handled 3/4 ton without much problem. My friend told me to stay away from diesel oils and try to locate any old SF stock, which I found at a WALMART of all places. I've learned you have to pay attention to what you put into these old cars before you unknowingly ruin a motor.
