thinking about swapping an st motor into my gt...., does better on gas Options

[celicaST]

just so you get an idea of how bad my car does on gas....

i have just over 1/4 tank left, and i have 155 miles on this tank, mostly city, some hwy...

it shouldnt be going through gas that quick. theres a whole list of possible causes for that so im not even going to guess. i would suggest an all around maintenance check.

[95gtschick]

yeah i'm getting that done tomorrow.

[hata]

man if you we're local..i'd say we can swap motors

[yungazzdriver]

well if u want i can trade motor mounts wif ya????

[TTE]

I think you will be better with 1.6L 4afe from Paseo.

this is something that has bothered me about my car since i got it.

i drive SO nice, and i've changed my plugs, wires, fuel filter, fuel pump, check my tires consistently (every week), etc....

but yet i can't even break like 250 miles to a tank in town driving (driving only 5 days a week to work and back, no extra trips).

What tire pressure are you keeping in them? Hauling anything around in the car with you? Any maintenance that could hinder gas mileage by casuing friction on the wheels (idk like wheel bearings, e-brake, etc)

any mods to the car?

[soulshadow]

I should smack you if you were to swap an ST into a GT. Who the heck would want to install something less in power for something that is already faster and stronger ?

tire pressure? i dunno, 32? whatever it says in the doorjamb. and no, i don't carry anything with me in the car, i never use my e-brake unless i'm parking, and wheel bearings, i have no idea.

i'm getting my car serviced today by the best dealership in town to find out what's wrong with my gas mileage.

but before they do anything they're calling me to tell me what it is, cause a lot of the time i can do it by myself or with my fiance's help. and it helps that i have a friend who works at the dealership i'm getting it serviced at, cause he can do it at my house then ^_^...

lol, i know i know, everyone thinks i'm an idiot already, i was just considering my options.

[pokemeintheeye]

eh i can pull in a good 370 on a tank, but its pushing it, I alway fill up at half a tank becaues i worry i'm gana get stuck in traffic for 8 hours and run out of gas, or just because i think the gas station is a good place to meet single girls my age where my car can start the converstion for me. (yeah I'm that desparate.)

and I hope your kidding, the little money your gana save on gas is not gana cover the cost of having a motor swap, just get a variety of fuel cleaners and injecter cleaners and a maybe a nice tone up.

Whether you're worried about getting stuck in traffic or not. It is best not to run it down to the last gallon or two anyways.

[yungazzdriver]

hahah man i think u shuld do it flintstones style and cut out the bottom, i think u can get 2 mp on that (man power) yeha way better than horse power ,

[Cutrara]

I skimmed through this topic but didn't read it the whole way. Did anyone mention your O2 sensor might be bad? I was working in the engine bay and had mine disconnected and I forgot to reconnect it. I got like 200 miles on a tank, but it was weird, no CEL.

[creis]

eh i have run with a bad O2 cencor, did not get bad milage by anymeans, maybe a little below normal, more things then that have to be wrong to get that bad of milage, maybe your fuel guage is off (although you would probably notice if your only putting in like 5-6 gallions. at the pump) try re-setting the ecu, and when you start it up in the morning let it idel a bit but look for excess gas out the exhaust. could hook an air/fuel guage up and see if its running really rich.

hopefully the doc found out the problem with it today.

[95gtschick]

well everything is fine...

our car's are supposed to get approx. 25mpg and i'm getting 22 and they say that's okay.

[Valo666]

Krysten, i had the same problem, i was gettin horrible milage. I was drivin 40 min to and from school every day and i was fillin up every 3 days. What i did was, change wires, plugs, cleaned air filter, oil, wheel bearings, got nitrogen in my tires so they wont deflate as easily, checked my cylinder head, timing belt, P/S belt, greased up every thing in the front and rear end and been takin it easy. Now, this week alone, i went out 2 my friends place on the other side of the city, to and from work daily, picking up and droppin off my gf at work daily, gone shopping, and just been crusing. This now im fillin up every 2 weeks.

[95gtschick]

what about injector cleaner?

[spunky393]

tell you what, this is just a whim, but look around the gas tank. make sure where it is welded from two pieces to one, it isn't leaking just a tiny bit around it. it took me a long as time to figure out that's why i wasn't getting good gas miles on my 91 mercury capri with a 1.6L engine in it. the gas tank was leaking at the front of the weld, just a tiny bit, so it wasn't leaving any type of puddle.

also, what weight of oil are you using?
check hoses that come and go from your under-hood fuel pump, etc. etc.

make sure they're not crack and stuff. after you got some heavy pressure going through those lines, it could be leaking out.

[elvasoshexai]

wow... i wish i could see the #s some of you people get... i get 20mpg highway driving and 19mpg mixed... when i was trying my best to conserve gas... the best i was able to get for all city(well.. suburban) driving was 21mpg...

I think you could use a tune up lol. My Mustang GT didn't even get that bad of mileage

[Sev408]

yeah 20mpg is pretty bad. I think i pulled 460 out of my tank last week.

I would look at your sparkplugs, wires, injectors and if you havent replaced your timing belt yet I would. It wont really affect gas but it needs to be done at around 110k.

[95gtschick]

i filled up today and calculated my mileage.... 17.83mpg. yeah, stupid dealership. totally calculated it wrong. they said our cars are only supposed to do 25mpg, and mine was doing approximately 22... i think not!
