99.9% certain that the Toyota ATF WS and Asian WS are synthetic basedI agree. On top of this data, the simple fact is that Maxlife is also a Synthetic Blend. The OEM and Aisin are pure mineral based. The Amsoil and Ravenol are pure synthetic. There is zero doubt that synthetic is superior to mineral based lubricants as far as longevity and protection.
Sure, you can just change the mineral based lubricants more often and be just fine. If that is someone's schtick, cool. But to naysay something that is more than likely superior just because it isn't something you want to or feel worth it to do, doesn't make sense logically. A kind of Fanboyism.
I also agree about providing evidence. You can't really prove there isn't something wrong with the oil. All you can do is look back at actual data of users and see if there were problems using it. If there isn't any comfirming data, then the assumption should be made that there isn't...until there is confirmation that there is.
