Yaris Gas Problem

[Lafiro]

OK, yes once I dont know why I ran out of gas, and had to push the car to a gas station, put gas, and after that day it went from 32 down to 24mpg. I took ti to the dealership and they blamed it on a bad tank of gas which looked/smelled bad.

Then a few weeks later and multiple tanks of 87/89/91 octane, still the same 25-27mpg.

I took my 2 subs and amp out, my donut, and put my stock tires/rims on; and It only did 1mpg better on average for two tanks.

I said to hell with it, put my 205/40/17 back on, and still got the 27mpg.

Now, I got pissed, went back a few weeks ago, and they did not want to do anything really, they just told me "the uce didnt report any errors so nothing can be done; and that the road test showed everything within ""spec""."

Well, its been a while now, and its still doing bad on gas.

I said to myself, no more driving at 80mph on the hgihway, and no more reving high betwen gears (like 3-4.5k)

I went normal the whole tank, mostly highway driving at 50-60mph. And guess what!!!!!!!! Still the same damn 27mpg. WOW I should imagine that with driving normally like an old person I should atleast seen 36+mpg average, but no.

When I first got the car, I was getting 35-38mpg average. One day went on a long trip and did 90mph the whole time, probably 250miles. I ended with 36.5mpg that day.

Now I do 60mph and dont rev high anymore, and somehow Im down to 25-27mpg range? What the F is this about.

Yes I have a 5door automatic.

yes I made the mistake of letting it run out of gas.

Yes I make the mistake of letting it run down till it flashes fast ALL the time.

So What is wrong, how can this be fixed? This way once its fixed I never again let it drop under 2-3bars.

Please dont harass me on my stupid mistakes, I'm already pissed enough at everything.

Thank you.
