  a- Standards, shown in black, are established by API, SAE and others. Ranges, shown in teal, represent the high and low data ranges for the major's 5W-30 API SM GF-4.

  b-Test Method used for metal analysis is ASTM ASTM D5185.

  c- ASTM D5185-09 Reproducibility by Element.

  d- The specification of 15 max is expressed in two significant figures and therefore this average of the two results meets specification.

e -This product is labeled as meeting API SF which is an obsolete specification and is not recommended for passenger cars built after 1988. In addition, this product is labeled as meeting API CC which is an obsolete specification and is not recommended for diesel engines built after 1990. The product label does not adequately warn consumers of this limited use.
