I went 125 miles with all my pips last weekend on a very full fillup, but now I'm at 305 with 2 pips left showing 43.7mpg on my screen. If I insert any short, 10 minutes trips with a tank, the mpg goes steadily down. This is why I haven't hit 50mpg (close though) on an entire tank.EJ23 said:Last week I went 115 miles with all my pips. I only filled up with 8 gallons. My tank never holds more than 8.5.
