      A:

      Hi Russ, glad to help you! This Motor Medic Lead Substitute (Part No. M5012) is universal and not vehicle specific. It allows older engines designed for use with "leaded" gasoline to run safely with low lead or unleaded fuels when used as directed and protects against valve and valve seat damage in engines with "soft" valves by coating parts with a protective film designed to prevent valve recession.
