I ran a fuel system cleaner... I got about 250 miles on that tank... didn't work. Next= O2 sensors.
let us know if it works. i got 21.4 mpg on my last tank with a brand new air filter. not very good, huh.
Check your tire pressure, that has alot to do with fuel mileage. I got 390 miles last week on 13 gallons, so I got about 30 mpg.
does the car have a tire pressure reccommendation or should i go by the tires' specs? the 21.4mpg was only city driving but it's still terrible.
I have larger tires on my car and I still get bad mpg. It has to be the O2. Or I need to reset my ECU and see what happens.
resetting the ecu didnt help for **** for me.
I did a full tune up a few weeks ago and the MPG didnt change. Imma try fuel filter in the near future.
i thought the fuel tank held 15 gallons not 13
yup holds 15 light turns on at 12 with 3 gallon reserve.

It has a 16 gallon tank. but yes 3 left after the lights on.

I just replaced my fuel filter pcv valve and injector cleaner. It seems to run better and smother and accel a lil faster.. but not to much of a notice.. Hopfully it will help with milage.

Also why are there two posts about this fuel ?
This one was brought back from 2003. The other thread is recent.
I've never seen my gas light go on when my tank is near the end or I just dont let it get that low, once its below that last line, I refill.

cant you just try a higher octane,i might try an fit a octane converter,it fits on the fuel line after the filter and converts 96 octane to 99,costs £55,might be worth it,any way what are you guys complaining about,at least you dont pay £0.79 per litre,that works out about £40 per tank,scandelouse!!!!

converts octane? yea, i'll believe that when i see real proof, other than claims from the company.

i recently installed a new air filter, and today i put in a new fuel filter and oil filter and i changed my oil. ill see if that helps out at all. what does a pcv valve do?
pcv = Positive Crankcase Ventitation

after what i did, i went from 21.4 to 24.2 mpg but i did more highway driving so its not too accurate. can plugs be the problem? i dont know if my plugs have been changed at all. i bought the car with 59k and it now has 64k. how much should i expect to pay for new plugs (performance in mind too) and how often should they be replaced?
irridium=$40ish dollers. You can install them yourself.

Stock plugs(all you really need) =10-$15 tops from toyota
