I didn't say or claim JASO "tests to verify requirements" or anything along those lines. But as I've mentioned before in these discussions, in order for JASO to have specification documents they know what tests data needs to be submitted by the oil manufacturer in order to meet the their specs and get the oil registered.JASO doesn't test to verify requirements... they only register oils at $365.00 a pop times 1,537 JASO registered
oils = $561,000 profit... Even if an submitter's paper work fails to meet specs their name will not be identify so
they will not lose market share... in other words JASO knows who failed but the public will never know...
In my opinion JASO is not much help because testing whether the oil pass muster or not falls right back to the owner...
The "muster" falls on the oil manufacturer regardless of JASO or not if they claim their oil "meets or exceeds JASO specifications". In order for an oil manufacture to meet that claim and put it on their bottles of oil they would have to do the same testing that JASO requires. If the oil manufacturers who make those claims actually do the tests and meet all the JASO requirements or not is left only to trust of the consumer since there is no verification from a 3rd party like JASO.
