My understanding is that there is a standardization for specification for lubricants, no secret ingredients . A federal law was passed years ago that manufactures could not void your warrantee by using a non manufactures product as long as it met the proper speciation, motor oils have a number of specs , can not do any harm by using a higher spec , you certainly wouldn't want or willingly use a lower spec oil than called for or paid for
