Terrible Fuel Economy Options

[97sccelica]

Honestly speaking... 20 mpg or so is very very poor.  Your cars may need some serious tune ups.  My Celica got 38-40 mpg during a road trip last summer... and still currently gets well over 30 mpg around town...  Time for a tune up perhaps?

Oh yeah... and I drive the crap out of my cars... ;]

ain't that the truth

i got 25mpg in the city when my ST was turboed!

currently my sister is getting like 21 mpg. thats just horrible. i assume its her driving, but i will change out the plugs, air filter, fuel filter, and maybe even the o2 sensor.

btw, my wrx gets 21-22mpg in the city, and believe me, there are times when i really get into it. lowest mpg i got was 16mpg, but that was for the very first tank, which included the test drive, and showing everyone what the car had.

30mpg on the freeways

Lab vs Reallife

Spoke to the Toyota service rep., he suggested that you are better to compare to vehicles of the same age and model, then the quoted stats from Toyota. So looking at my post, we have: exxtractor (me), dstrbcelica, drocay, funnyboy, fallenhero and MrE (not sure model) who are all reporting real world fuel economy of around 20-21 MPG. I don't think I'm really that worried since it seems for many of us with the 7AFE 1.8L from 94/95 this is probably ok. Sure you are always going to get someone who gets 30 MPG with their 94/95. But to spend the cash to replace the fuel filter, oxygen sensors, and a tune-up on a 10 year-old vehicle... I'd rather not. I'm just going to do my routine maintenace and hopefully I can get anotehr 2 years and then I'll buy a new car.

dude... I can smell gas in my exhaust when the car is running. it's so flaimin out of tune you could blow fire out the tail pipe.

Jon= getting the car worked on after brakes are installed.)

[Drocay]

but do any of u guys know how i could check to see if o2 sensor is problem its kinda expensive to just buy one and wing it and then not know which o2 sensor is causein the problem.

thanx.

Remove it and you can see how dirty and cloged it is. I eye balled mine and changed them. They were rusted over and all nasty lookin. Otherwise, wait for the CEL light.

Even still 20 is ridiculous. As far as the cash goes if you spend maybe 300 bucks for all the stuff needed for a tuneup and DIY, you will save easily over that amount of gas in the 2 more years you plan on keeping the car. How many miles does your car have now? If you keep up on planned maintenance....not just regular maintenance, your going to keep your car operating at maximum performance. You mentioned you got the plugs and wires done at 97,000 so Im guessing you dont have much more than that. My 94 ST auto when it had 103,000 averaged 32mpg.

As far as the lab vs real world mpg....I now have a 5 speed GT. Toyota says 22 city, 28 highway. In summer I AVERAGED 29mpg. Now I average 27. My car has 105,000 miles.

iono...i still haven't filled it all the way yet. but, it's better. i'll bump this again after i've gone through a full tank.

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!!!!

[Drocay]

any updates man.

[FallenHero]

I ran a fuel system cleaner... I got about 250 miles on that tank... didn't work. Next= O2 sensors.

[rocky2006]

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.

[Rjb23]

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.

[rocky2006]

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.

[FallenHero]

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.

[rocky2006]

resetting the ecu didnt help for **** for me.

[LatinKraze]

I did a full tune up a few weeks ago and the MPG didnt change. Imma try fuel filter in the near future.

[LewFX]

i thought the fuel tank held 15 gallons not 13

[Drocay]

yup holds 15 light turns on at 12 with 3 gallon reserve.
