Here’s the problem with oil analysis; it requires multiple tests to establish a trend. They are correct; slightly elevated lead results COULD be nothing more normal break-in IF lead was still used in engine bearings. Modern bearing are faced with babbitt which is predominantly tin and antimony. If I were you I would pull another test when the engine has at least one thousand more miles on it along with an oil filter inspection.
