a- Standards, shown in yellow, are established by API, SAE and others.

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

c- ASTM D5185-09 Reproducibility by Element.

d- The specification is expressed to two significant figures, therefore results up to 15.5 are considered on specification.

e- The specification for phosphorus in an API SL motor oil is 1,049 ppm.

f- The results are within the API Expanded Range for Cold Crank Viscosity.
