Terrible Fuel Economy Options

[Digndoug]

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
