I dont recall the day very well, but in my fuel log for 1-16-18 you will see some pretty horrible mpg numbers. Mostly because roughly 8 to 9 EV miles were actually generated during "engine running due to temperature/erdtt". Which made gas mpg look extra bad and EV miles look extra good.

I think 2013 and up had options to change erdtt from 25F to 15F, would help a little.

Edit: there is a way to defeat erdtt entirely by installing a correct value resistor where the outdoor temp sensor is.
