I'm having gas mileage issues....

[cavaliers60]

My car is really making me mad now.... Ever since I got the new tires, I've had the worst gas mileage ever! before my new tires, I could drive to Terre Haute and back (about 1 hour 10 minutes up and the same coming home) and only use about 1/4 of a tank. Since my new tires, I used half a tank of gas on the same trip!!! WTF is wrong with my car?!?!?!?!? Are new tires suppose to make your car have crappy gas mileage????

Tire pressure, driving style, winter fuel blend..?

[cavaliers60]

My tire pressure is set at 32 PSI. It's what it's always been set at. Should it be more?

My driving style isn't bad... I don't floor it, nor do I speed. As far as winter fuel blend goes, I don't know... I've NEVER had bad gas mileage like this.

time for a new fuel filter?

[cavaliers60]

I was thinking that too.... I haven't changed mine since I bought the car so I really don't know how old mine is.... How much would it cost if it does need to be replaced? And would I be able to do it myself?

[Steven01]

Well Here Is a Example of Mine. My New BF Goods Give me 400kms to a tank Little more becase i dont drive it till empty... BUT since WINTER is NOW HERE at LIKE -20 to -30 + windchill I only get about 300. And In the summer I belive I drive harder.

[cavaliers60]

yeah but still.... I have NEVER had that much of a decline in gas mileage. It's like I'm only getting 8 MPG..... I haven't done the math cause I haven't filled my car up all the way recently, but I'm sure it's pretty close the that 8 MPG mark.......

Question.... Where is the fuel filter located?

[Steven01]

Well if you see im loosing 100 Km Per tank in winter thats 1/4 of my tank evry time I fill. And i fill my car once a week Atlest sometimes more. I spend about 45$ to fill.

[cavaliers60]

I still might replace the filter since it hasn't been done in a couple years..... Depending on how hard it is to replace or if I have to get it replaced by a professional...

[[ion] C2]

calculate your mileage.. don't just go off your assumptions of what you're getting before jumping to conclusions lol

[cavaliers60]

Oh I will... lol I would also like some info on replacing fuel filters and anything else I could do to get better mileage. I just hope it gets better....

[Ryan from Ohio]

Winter fuel and cold weather sucks. Over the summer I topped out mileage at 320 per tank. Now Im down to 250. Thats a big difference for a 12.4 gallons at fillup.

Im only getting 20 MPG now.

Something s not right with these cars I swear...

[cavaliers60]

Well, I noticed that my car starts really hard too when it's extremely cold out too.... I hate cold weather....

fuel pump?

[pimpalero2003]

i didnt have a problem with mpg when mine went out.

[freakout]

Make sure you check the tires cold. You just had them put on IIRC. If they aired them up in a warm shop, they won't be the same outside. When the temp drops the air is denser it takes more to push your car through it. The fuel filter is back by the tank. An o2 sensor will screw up mileage as well. Even though it's not throwing a code it can still not read corectly messing with you a/f ratio burning more fuel.

[pimpalero2003]

who cares about mpg anyway these days

[rustyballs_69]

Your gauge could be reading wrong. Its common with the aleros.

The fuel filter is under the back of the car. Its behind the gas tank.

[cavaliers60]

So, I could change the filter myself then... That's good! only $8 for a new filter! I might go ahead and do that..... I'll look into the o2 sensor.... Where would that be located? We have two of them right?

[rustyballs_69]

How many miles do you have on it?
