API has been testing off-the-shelf engine oils carrying the API Starburst and Donut under its Aftermarket Audit Program (AMAP) since 1994 and in 1999 began testing API-licensed product dispensed from tanks and drums at quick-lube facilities, service stations, auto dealerships, and truck maintenance facilities. Since 1994, API has tested approximately 7,000 API-licensed oils from around the world.
Interesting. It appears the API's AMAP program tests oils dispensed from tanks and drums, but doesn't test oils marketed in bottles.

API went on to say, "Under AMAP, API-licensed engine oils are purchased in the marketplace and bench-tested to determine their physical and chemical properties. The results are compared to licensee formulations on file at API. Conforming oils show bench-test results that are consistent with the formulations and meet program requirements. All samples undergo elemental analysis, viscosity at 100°C, and high-temperature/high-shear testing. They may also be tested for cold cranking, pumpability, volatility, foaming, filterability, rust and corrosion inhibition, and shear stability. Product packages are checked to make sure they correctly display the API Marks and carry product trace codes. A number of bench-tested oils undergo actual industry sequence engine testing for oxidation, deposits, sludge, varnish, and wear."
It's interesting to that a number (but not all) oils undergo testing for wear (which could include sequence IVA) under the AMAP.
Since not all oils are subjected to wear testing as part of the auditing process, the issue could have escaped API's notice. However, since the API was made aware of the issue, you would think they would take an interest beyond just explaining their process. Their statements explain how E-M's goof (hopefully a temporary mistake) may have gone unnoticed, but it doesn't explain why no additional actions are apparently needed. Though not intentional, the API's explanation and failure to take further action serves to undermine their image and credibility.
