Well...not exactly.
API’s Engine Oil Licensing and Certification System (EOLCS) is a voluntary licensing and certification program that authorizes engine oil marketers who meet specified requirements to use the API Engine Oil Quality Marks.
http://www.api.org/certifications/engineoil/index.cfm
This means that any oil blender who claims to use a base oil from the approved interchange chart, and buy an approved additive package, can put the API labels on their product. Each brand and grade of oil is not tested. There is very little auditing to see if every blender actually uses the correct ingredients correctly blended in their oils.
I'll stick with a top quality name, not a lowest price outfit.
Would not this same logic apply to the big name guys?
There are those here that have their oil tested but how do we make sure that all of the oils meet these same standards?
We dont really.There could be millions of bottles of oil that are not what they are supposed to be and people are unaware of it.
