Oh wow is all I can say. So this last tank is finally up, and can I say what a difference. I drove probably what a normal person does everyday and dropped my MPG down to 25. That to me is crazy I only got 292 miles on the tank. I have been averaging almost 30-32 mpg at 5 mpg more I get almost 55 more miles a tank that's huge considering I make one trip every week that is 60 miles I basically get a free trip. Ok baseline is done I'm ordering a heating pad today due to the cold temperatures, even with the car being in the garage. that will help out a ton.
