The reason i ask is that my car only gets 200 miles per tank in the city thats rougly 13 MPG anybody else have this problem?If not what can i do to help the MPG car has 35K on it everything seems to be fine

What year is it?

Low mileage doesn't mean new.

2002

Six years old. I'm guessing it's still on original plugs and wires. I'd swap out the plugs and wires. Clean the MAF. New front O2 sensor. Low tire pressure.

How's it running other then poor mpg?

Like a dream lol.

Yea i neevr did a tune up on it ut thats because i dont drive it a lot. Whats normal MPG for it tho.I had a SE and a GTP and they all did 200 or little under 200 per tank.Car eats more than v8s and its scary

On a GT I'd say around town brooklyn I'd expect mid teens. In a "normal" city I'd expect upper teens to low 20s.

How much idling does your car do when you do drive it?

3 rpms 3.5 but when my car is just idling the rpms stay on 1 it dontesnt go to .5 i dsuno why

my gt stays around 22/23 mpg and that is both country roads, no city here, lol and highway

ya same here my mpg stays at 23.9...i wish it would be ALOT higher...but its not...

I was getting about 175-200 miles when I was in Pittsburgh (city miles). Here in the country part of Indiana I get around 300-350 miles on the tank.

In city miles I get alil over 300 Miles per tank.... Thats babying it...

Highway miles (around 80mph) I get about 350 Miles per tank

~400 miles a tank, mostly highway. DIC says 23 mpg. No real tuning yet.

wow 400 lol when my car gets to 200 im excited lol.Thanks for answering guys

one time doing 60 I got almost 500 miles on highway ( I think tail wind helped)

yeah i get around 250, with mixed driving, but i will be putting on my new dp soon with a new o2 so i hope that helps

i get about 34 mpg highway, 23ish city.

its all in the tune

City MPG is all about how you drive. You need to accelerate slower and look ahead. You will learn to back off teh throttle sooner and still get to the next red light. Yeah I get people riding my back bumper for the last 50-75 ft before we stop, but why should I continue to be on the gas until I have to break. Also leave for work or any other appt 5 minutes earlier. That way you are not tempted to push your speed or race thru the yellow/red light.

Liek others have said, tires should be 32-35 cold, empty the extra crap out of your trunk. Never try and accelerate up a hill if you can help it.

I have also found that my car will lock up in OD at 43MPH. If I can set my cruise in town, I will. The car will stay in 4th gear.

I like filling up at this gas station at the top of the hill and reseting my mpg. it'll read up in the 40's by the bottom of the hill. Then it's back to reality where i get 18-23 depending on how pissed off i get on the road durring that tank. I drove staring at the gauge one tank and adjusted my driving to make the numbers go up. I got a tank to average out at 28 mpg. That was mostly highway never breaking 55 or going over 2500 rpms unless needed. Amazing mpg, but driving that slow drove me insane.

yea everytime i went home from fort campbell to fort wayne ind which is like 45 min from the mi state line and 20 min away from the ohio state line id make it on about 3/4 of a tank and thats a 425 mile drive doing anywhere from 80-100 depending on the radar detector!!

I noticed yesterday I've lost 4th gear in my trans. Interestingly, it doesn't seem to have really hurt my gas mileage, and the 2900rpm @ 70mph has REALLY improved the noise level inside the car. So freaking quiet in comparison. Cruising at 70 in 3rd gear I was getting 26mpg on a flat road. Makes me wonder how much the OD really helps us. Must be very poorly tuned from the factory, should kick down at lower load than it does.

At 70 on a flat road I can get 34 mpg so you tell me how much it helps or hurts?

You need some maintenance and/or tuning. I would say all city driving, you should be at minimum 250 per tank, 15.5-16 gallons used. It is in the way you drive to. Actually pay attention to how you drive. Accelerate like there is an egg between your foot and the gas pedal, and tell the other drivers to go around. Have your tires inflatted properly.
Before a tune, I was getting 260 max in a tank on mixed driving. Then a tune came along, and I was pushing 350-370, more highway than city.
I have seen my mileage drop recently on the highway due to probably untuned in a month or two and the ethanol in the fuels.

That's why I make a little sacrifice in the wallet, because it helps keep me sane.

I live in heavily congested Northern NJ, and the MPG is in the 19-22 range. Have no idea on the tank, since I rarely fill it.

What else should i do besides changing plugs wires and 02 sensor
Thanks

fuel filter

Theres no way for me to extrapolate from your example to mine. However, if you were to reset your DIC on the freeway after forcing the tranny to 3rd, you would have a valid comparison (34 mpg w/ OD, x mpg w/o)

Well in 4th at 70 Im just a hair over 2,000 rpms. So 800+rpms is quite the difference when it comes to mileage.

Almost 400 per tank with my gt

Welcome to the board.

See, you would think that, but my experience hasn't been that way. I think even though the engine is spinning faster, the reduced engine load offsets the high rpms to some extent. *shrug* W/o having my 4th gear any more, no way for me to test.

My DIC says I average 22 MPG. And I drive 80% highway .

I know I need a more efficient tune based on my A/F ratio on a dyno taken several months ago. Just can't afford to take it to Intense or ZZP to do it. I would like a tuner so I can do it myself but its my DD and I'm becoming less weary to experiment on it.

I need tuned to bad.

well i beat my own record today 159 miles on a full tank im going insane over ehre lol gas is 4.20.You guys really think a tune up will improve MPG by that much

I would like to know your driving habits. Do you let your car warm up? Do you start it and drive? How many stop lights do you sit at? how long is each light? How far is each commute?

Run a can of quality fuel system cleaner the next two tankfuls. I like seafoam, lucas, BG 44K or Berrymans B12.

If your car is not a GTP, do not buy premium gas.

How does your tire wear look? Get it aligned.

Change your Air filter.

Buy some mass air flow cleaner and clean the crap out of your throttle body.

Sure theres not a hole in your tank?

Herc

i drive around 40 in a city and 70 75 on a highway.Race rarely becasue GT is kinda slow(thats why i want a turbo ive been asking about)
Lots of lights brooklyn and manhatten is a pain in the butt.I Autostart the car for about 4 mins everytime im bout to drive.Commutes always different.

chevyman

yea ill deff going to put the cleaner.Ive been puttin Premium in a car ever since i bought it couple of years ago.I realy think premium makes your car drive better.New filter got it 2 mnths ago tires look almost new still.As for the rest of the stuff im going to autozone tomorow lol

Zalfrin i checked it yesterday accualy no hole

plugs wires 02 sensor throttle cleaner fuel system cleaner fuel filter.Is that good enough or more thingd avaliable

I used to always get things done in shops but im tired of being robbed there thats why its all new to me lol

THANKS A LOT FOR YOUR HELP GUYS

those plus properly inflated tires are the standard list for improving mpg. don't waste your money on premium, you don't need it.

When i just bought the car people told me to put synthetic oil and premium gas so ive been doint that for a while.Does it really make no difference

how much air should i have in the wheels

I had a professor at Kettering University (formerly GMI) that said premium actually doesnt do anything better if your car doesnt need it. He said its good every once in a while to kind of clean things out, but not necessary. Since you have a gt, no premium necessary.

i mean in the tires

O yea??Hmm thats something to consider

Kettering eh? That was my second choice for school, but now I'm glad I steered clear of the auto industry (not all they do, but heavily involved).

just over 500 miles at 75mph
