Never done it on any of my Toyota vehicles. (2012 Camry, 2014 Avalon, 2013 RX350, 2015 Corolla…) Never had an issue. I just follow the maintenance schedule. I think it’s a waste of money people like the car care nut scare people into doing and then it becomes gospel. but if you enjoy throwing money away, someone will happily take it.
