Dodge Neon low mpg

[Antigrav01]

Well now... This might be helpful. I found out how to see error codes and I got 456 and 440. I think 440 means theres an EVAP failure and 456 means an EVAP leak. I could be wrong though. I only looked on a couple websites.

My temp gauge was always at the second line, the one a little below half. So anyways I guess my point is, even if it seems low on the gauge, it may not actually be, see if there is some way to verify the temp or where it should be.

thats right where it should be.

evap systems are a pain to deal with...i had an evap leak on my old car and i replaced all but the lines to have fixed the problem it would have involved replacing all the lines including the gas filler neck

Im starting to feel like I got ripped off with this car. I expect things to happen to it, but not this soon after buying it.

Im bringing back this post, but I thought id give an update.

The only thing I did was change the oil. Ive since increase my mpg to 24 as long as im careful. Whoo! Pathetic still, but hey, better than 22. Also...I just realized something. The station I always use to fill up uses 10% ethanol. Big sticker on every pump that I somehow missed. Now I know I still have some maintenance to do to get my car back to its proper efficiency, but that ethanol mixture is definitely lowering my mpg.
