Ever since I got the car last Oct, my mpg's were avg in the mid to high 40's while it peaked once up to about 51. All these times, the MFD milage was never more than 3 miles off. Today, the MFD was giving me a avg of 50.5. I calculated the milage at the pump and found out that it was actually 57.33! I knew something was up when it took the car 484 miles to get to the last square in the guage.
wtg!! i am getting the same readings too. it must have something to do with the warmer weather or something. i have had 5 tanks in a row where the pump figures have been over the MFD. up until this started happening, for the most part each take turns being high
my pump readings have always been higher than mdf. When mdf achieved 59.1 it was calculated to about 62. Currently i'm calculating 372 miles at 50... 50... i think it's 57.3 or somethign like that. Since i use " no arrows " it's actually higher.
I climb 3000 ft. everyday and my MPG has been about 47. Last tank I hit 50.4. What a great psycological difference!
