They say to perform the same function again but you have to there to do it.

So if you set the remote start and let it run for 8-9min, then re-did the remote start with it running it would run for up to 18-19min with a maximum of 20min allowed. As far as I know there is no other way to make it longer in a single hit of the remote start.



As for my mpg, I got 10.6 in my truck last tank and I use my remote start everyday now LOL.
