hi there..im just asking this...is theres a difference with gas mileage with the weather at.....106F....i look a little drops of my gas...with that temp. With 77F or less the car runs excellent(talking about gas) but i dont know if im wrong....i check my ecu etc, tire pressure etc...and everythings ok.

 

I've noticed that my car gets better gas milage in warmer whether then it does in winter. When its like 80 it seems like my car goes further on a tank of gas. This could be caused because of additives put in winter gasoline, as for your problem between 70-100 I would doubt it would really matter. Make sure you have 32psi in your tires, check your fuel and air filters as well.
