He further suggested that I am trusting XOM to meet the Ford specification (WSS-M2C930–A) instead of simply using a 5W-20 that meets WSS-M2C930–A. For reference, M1 AFE/EP 0W-20 meets or exceeds Ford specification WSS-M2C930–A and WSS-M2C945–A.
We were hijacking the OP’s post and so I thought I would start a new post and the point of this post is not to debate Trav and my points of view (or who is right/wrong). It is to ask does Ford (or any OEM for that matter) certify that oil made by any oil vendor who states it meets OEM specification “X” actually test or certify the oil to see that it does? To my knowledge, no OEM does this—I would even question if Ford does this for Motorcraft oil (currently made by COP).
Thoughts? Do OEMs test the oil or simply leave it to the oil vendor?
Here is some good insight into how this works:
Oil Additive companies (Lubrizol, Infineum, Afton etc) have entire divisions dedicated to working with OEM's on the development of new lubrication technologies and specifications. Generally the company that helps develop the spec gets a "leg up" on the competition by creating the package and associated sample formulas which they then market to their blenders. Usually the OEM spec is released and then other companies can compare their testing results with the posted spec or submit a package of tests for approval to the OEM as JAG described.
The resultant formulas are then typically describe as:
Approved for - these are the ones containing the DI pack developed in tandem with the OEM or sometimes those which have received some sort of formal review and approval by the OEM (like those who use Dexos)
Meets or Exceeds - this description is most often used by products who can prove they meet the specs as published. These probably weren't reviewed by the OEM but can be used with confidence.
Suitable for Use - these products typically have the features required but maybe don't meet some minor test in the published spec, or maybe uses an ingredient that wasn't in the original approved formula but is a proven replacement (ie a bright stock replacement additive vs using actual bright stock)
When a blender (major or independent) makes these claims on their products it is often because the additive manufacturer provides a list of specifications that using their package is either automatically approved for or is suitable for (ie API SN or some of the Ford Specs you referred to.)
