The normal drain interval for transaxle oil is 60k miles per Toyota. However, we've found it needs to be closer to 30k miles. Your mileage may vary.

In my case, I was looking to see if this second pan heater would last more than a year ... no. So I'm thinking 'outside the box' for another solution ... a Prius docking station at home.

As for coking the oil, that is why I'm interested in a steam heating solution. The temperature will never exceed 100C so the oil will be 'safe.'
