slick Posted October 28, 2006 Report Share Posted October 28, 2006 Ok my HUD is saying I average 6 mpg. WTF???? Why is my car getting such shity mileage? Well... after reading countless threads from you, sounds like you beat on your car a lot. Obviously not good for gas mileage. Quote Link to comment Share on other sites More sharing options...

mfewtrail Posted October 28, 2006 Report Share Posted October 28, 2006 28 city? how the hell. Miscalculation, that's how. 28mpg in the city might be possible for a split-second, but that's about it. Quote Link to comment Share on other sites More sharing options...

No joke. here's a pic of my mpg after filling up, reseting the DIC, then coasting down a long hill. soon as i got to the bottom and actually used the throttle, my mpg shot down fast!! but for me, my city driving consists of driving back and forth to work. 2 whole miles there, 2 whole miles back. my car idles more than its actually moving!! which is why i get 16-17 city, but freeway is like 28-29. i average around 21 since i do almost all city driving. Ok my HUD is saying I average 6 mpg. WTF???? Why is my car getting such shity mileage? Maybe someone is stealing your gas. :lol: Quote Link to comment Share on other sites More sharing options...
