  1. Use only unleaded gasoline.
  2.  avoid prolonged idling.

    Avoid running the engine at idle speed for more than 20 minutes.

  3. avoid a spark jump test.

  2.  While testing, never race the engine.
  1. avoid a prolonged engine compression measurement.

  2.  do not run the engine when the fuel tank is nearly empty. This may cause the engine to misfire and create an extra load on the converter.
