Gas Millage Issue

01-12-2006, 09:15 PM

ok people i have had this car for roughly one year. I bought it at 35000 its currently got about 47000 now. I change the oil regularly. but i cant get any more than like 180 miles per tank of gas. Is this normal gas mileage? What can i do to improve this i really am getting to the point where i cannot afford to drive

i have an 04 3.4L i sometimes get up to 280 miles per tank...once in a while a bit more. but usually i do get between 200 and 250 per tank. and i usually drive it hard.

obviously something isnt working efficiently in your car to produce this bad gas mileage. i get well over 30mpg with a fully loaded car (5 people) on the hwy.
check to see if it is leaking anything in the driveway where it sits, then bring it to your local trusted shop and tell them if its leaking any fluid or not, and explain your problem. there is NO way we can diagnose your car for you on here babe.

make sure your running better oil, make sure you have 100% electricity in your coils, wires, and plugs, also check your vaccuum lines such as your PCV...........and make sure your MAF is properally working.

and change your fuel filter?

Check your fuel pressure regulator... take it off make sure its not squirting out.... change all spark plugs and wires... change the coil packs.... change the air filter. that will solve it for sure if nothing seems obvious

Highway, city, going down to "E" or 1/4 tank, flooring it at every light, or not, 2.4,2.2, or 3.4?

Since I moved outside the city I avg about 20 MPG, just did 21.2 MPG filled up 11.5 gallons (3/4 empty) which worked out to 245 miles.

I have the 3.4 liter motor

driving respectively redog, or lead foot........if i drive 1/2 and 1/2i can get about 22 average, 24 if i granny it non stop, and about 18 if im driving like a maniac.........

yeah i usually average close to 30 highway and mid 20's in town, so i think something just isnt working right, or flowing right, id get something fixed, or i would also make sure you are doing your calculations right

cherrington17 · 01-16-2006, 08:41 PM

i get close to 30mpg, but when i do drive now its 120 miles at a time, at 65-75mph...

before i was driving long distances, i usually got like 20mpg around the town i live in.

3.4L V6 of course....

you have the 2.4, stay out of this conversation!

Anyhow, it happens to all of us in the winter itme. During the summer on the highway, i can stretch 400 miles to a tank. now in the winter with city driving, i'm sporting a nice 18 to 20. Its a combination of the winter fuel mix along with the fact that its just colder and it takes the car longer to get up to operating temps. also when you're running your defrosters, you're also running you a/c compressor and that never helps fuel economy. just some things to take into consideration. give it a wait out until spring/summer and see what develops.

my 02 3.4, with 57Kmi gets about 22-24 right now in winter, and i used to get 25-30 in summer and all i got right now is a K&N filter. filter did bump up my MPG by 1 though i was happy. specially at 3.30 a gallon( katrinas a BI#ch)winter gettin 320-340MPT tank, summer like 350solid 380 all freeway

Don't complain about MPG, I figured out the Delta's MPG

12.5 mpg both city and highway, which I don't think it too bad for a car of it's size

If the mpg really bothers you, buy a Prius

I just rolled in from a 416 mile round trip to visit relatives. I nailed 29mpg on the trip. Have been getting real lousy milage for the mixed highway city driving, but for all highway I'm pleased.

With my mods I get 28-30 highway and about 22-25 city depending how much city isn't highway.

This is also during the heart of winter. Let it be noted this is not babying it either.

AlbinoMonkeyRat · 02-09-2006, 10:28 PM

Check your filters. ESPECIALLY THE AIR FILTER. If the air filter is clogged up, then the intake is going to heat up and the air temp sensor in the intake will read that hot air going into the engine thus burning off more gas.

Also, make sure you're not trying to drive like Mario Andretti.

With a stock 3.4L and driving a mix of city & highway, I usually get 22 MPG. If I drive like its a race car than it quickly drops to 16-18 MPG. I found that your driving style greatly affect the mileage. My previous car was a 96 GTP with the 3.4L DOHC and it was much more tolerant of my occassional race car style driving without a huge drop in milage.
