Scott Wheaton, mentioned above and another person both tested the new Brad Penn oil. Using different labs both found the Brad Penn oil to have VERY low zddp levels. In fact he stated the levels were about the same as the genaric Wal-Mart stuff. He didn't believe the levels could be so low so he tested again and got the same results.
Summit is now selling an oil with zddp levels around 1800ppm.
