The "nothing blew up tests", or "the pile of failed engines" don't demonstrate for a second that they meet the industry tests that they claim.
They list the the ISO certified tests they have supposedly tested the oil against. The 4 ball test is only one of them. Check the data bulletins posted for each product and you will see.
