ELF (Total) products on the API list ? Only lists some API SN oils, yet I swear I can still find some API SL ELF oils on the shelves !
I won't trust the API list. Seems too short. Even on a reputable brand like ELF (TOTAL !!)
Even Q8 (Kuwait Petroleum Research & Technology), a reputable industrial lubrification company doing motor oils, have numerous API products in their line. Yet, only 3 are listed...
Can't find any europpean store brand (like your US Supertech), yet those are reputable oils here. I don't know... I'll ask consumer support. Maybe spend a few bucks for a VOA.
The API certification is the standard of motor oils and while a quality product may not need a API certification. Having one means there is at least a verified quality the product has. With your beloved Auchan there is no basis for it quality.
