Terrible Fuel Economy Options

[exxtractor]

Using 87 octane I'm getting approx 20-21 MPG.

Man my '94 1.8L ST auto is just getting brutal fuel economy... don't get me wrong its probably the way I drive, my typical commute is 45 miles round-trip (35 miles HWY/10 CTY), and I have bad habits like aggressive acceleration for green, driving 65-80 MPH on HWY. Last time I posted a few months ago it was 22. Amazing when I hear peole say they are getting in the 30's. Guess I should change my drivng habits... maybe not.

Have you done a tune-up on your car? Have you tried slowing down for a tank of gas to see if you get better economy?

It's possible that you need a tune-up or O2 sensor.

i don't think it's your driving habits. i'm having the same problem and i think we just need a tune up.

I was gunna say, I thought i was getting terible, like somthing was wrong. I was getting around 24 mpg, and thought that was crap. Then I replaced the plugs, cleaned the air filter, and started driving a l,ot slower and shifting around 2500-3 compared to 3500-4. I got then around 30 mpg. It seemed to much of a pain to drive like that though. So now i drive norm. I still will accel kinda quick, but shift into higher gears faster, and cut out the always trying to race people an ****. so now im getting around an average of 26mpg. I would say replace your fuel filter, that would most likley help alot and prolly hasnt been changed. Come to think bout it, I should do the same.

I'm pretty good about trying to take care of the car, had the plugs changed at 87,000 miles. Regular oil and service, but I don't belive the oxygen sensor has been changed... possilby for the life of the celica. Might do that at the next oil change. Would changing the fuel filter have any effect?

[hellsyphon]

Yes it will. A fuel filter clogged up with junk will kill your gas mileage. A new fuel filter wouldnt hurt and maybe sometime in the future flush your fuel line?

I just changed my fuel filter on my geo prizm (4a-fe). It wasnt all that bad to do. Just please remember to use TWO washers. One on the top side fuel line fitting(out > going to engine) and one on the bottom side of the out line. I forgot to check if both were on and it looked like my new fuel filter was a water fountain lol. The in line(from gas tank) is a metal line that you unscrew using a open wrench from the underside of the vehicle when its on a ramp or jacked up. Put something under the fuel filter too so you dont get it all over your driveway. I looked on my 95 GT and it looks MUCH easier to change on the celica than the prizm.

I don't think its driving because i'm getting the same and i've changed my driving habits. I remeber when i bought the car it was getting around 26-30. So i think i'll try tune up first.

[funnyboy117]

Yeah my auto ST hardly gets 20mpg and I only drive it hard once in a while, such as going 100 on the freeway once every couple months. Other than that it shifts when it feels like it, I hardly ever take it to redline.

I replaced my air filter a while back but there was no noticeable difference, let us know how much the fuel filter helps if you decide to try it out.

[FallenHero]

agreed, I get a bit over 20 also. I think it's the O2 sensors though.

[Kwanza26]

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... ;]

[Batman722]

Something is definatly wrong. I get 33-34 mpg with 148K miles on it. O2 sensor, fuel filter, and tune up ASAP.

[Mr_E]

For reference, I rarely see over 30mpg. 20-22 is very very normal. 7mpg is my record.

And UK gallons are bigger as well.

I'd debating attaching a bucket to the tail pipe to catch all the unburnt fuel it spits out.

Yeah... but these are 7AFE engines we're talking about here... You have a gas guzzleing snail... ;] Also, I don't think the UK has as many long straight roads as in the US so you don't get as good of cruising MPG also... =P

[Mr_E]

The man has a point.....

[soltrain]

augh! i just checked and I get about 18mpg. 18! ...maybe my o2 is bad after all.

[Drocay]

how would i go about checking if the o2 sensor is bad, i don't have a cel going off or anything?

[Borrazca]

Just saying the same as them all. get a tuneup. only reason i'm really posting is to say that i drive a 94 gt stick and i have probably worse habits than you as with the aggressive accel on a green light and about 100 down freeways. i run a 30/10 back and forth to school everyday. I get about a week of driving on 20$ of gas (2.18 over here when i tested). Round about 27mpg

[vangSTa_celica]

I just went from Oshkosh to the Metrodome in Saint Paul this weeknd back and forth and filled up twice. Averaged about 35 mpg.

EDIT: That's with 165,600 miles too.
