gas

[Galant306m]

im getting bad gas mileage. I was getting about 330 to a tank about two weeks ago and now im getting about 240 to a tank. My car smells like gas but isnt leaking any gas that i can see. no spots nothing just smells like it. i no that there is recall on the gas tanks ware they crack on the top but i called the mitsu dealer and they said that i dont have that recall, so im confused. I do have a check engine light but that has been on for a while now and i was getting perfectly good gas mileage even with the light. The code from the light that i have had is a idle control motor, but the car idles fine and dosnt act weird, im not burning rich cause i would smell that and my plugs arnt white. so im very confused as to what is the problem. and i just did a oil change last week when the problem began. Im thinking it might be a oil filter but im not sure ware it is, im taking it is a inline filter which suck cause ill break the lines when i change it. but any ideas to what it might be would be helpful ty.!

so what do you need? IAC or other?

or it could be on how you drive it, and where you drive it...

i think its the gas around here i buy from the same place, mostly everytime. I got to fill up tonight im at 227 right now on a quartar tank left im going to run out a lil farther ware i can get non ethanol gas, im going to try that cause a couple people that i said this to are having the same problem up here, so i don know if we got some bad gas or a bad mixture of ethanol. we shall see.!

I always get between 250-330 per tank. It kinda fluctuates for some reason. As on solving this problem, I have no clue.

EDIT: Holy snap, that could be the problem! When I lived in KC, Missouri, I was consistantly getting around 300-330, where the ethanol was actually more expensive than regular. Now back in Iowa, I consistantly get 250-300 where ethanol is cheaper and insinctively grab it instead because it shows a higher octane rating. But, I've heard, that even though it may show a higher octane rating, ethanol still has less "boom" than normal gas, right?

I'm not talking E-85, just the 10% blend you see normally in the midwest.

its crazy.....
but on the gs i get between 470 and 500 miles on a tank highway.....
and in the city, the gas light JUST came on and i'm at 389 miles... so i know i can take that to 420 easy w/o stalling the motor

Mileage usually drops in the winter. Up here in Alaska, mine goes from averaging 30 in the summer, down to 25 in the winter. I found this thread, below, in another forum.

Same here fellas. I was able to drive to PA back and forth with $20. Now, of course the gas is more expensive, but I can see my gauge droppin quicker than before, so I add another $10 for the same distance.
