  1. what is the zinc content of this motor oil. I believe a high zinc content can protect the engine’s timing chain and other metal to metal wear parts.

    1. Hi Don;
      Here are the specs:
      The DME has the following ZDDP levels:

      Zinc = 1,314ppm

      Phos = 1,206ppm

      The Z series motor oils have the high zinc capacity.
