Hey guys...i've recently started to notice that my gas tank guage is going down SOOO fast. I've done that thing on my navi to check my mpg's...and it said 15.2 - 15.4. That's terrible. What the hell is wrong with my car?!
Its never been this bad before.

 

Check to see if you added a brick to your right foot first. Then check for possible vacuum leaks.

 

then reset ur ecu and if problem persists, I'd highly suggest removing the paver from your right foot

 

has your area changed gas mixture for winter time

 

Hahaha...u guys are funny. I havent been driving too fast lately. And i've been trying to take it easy on gunning it everytime i get a chance. Yet still i feel like im getting 10mpg....HUMMER STYLE! Before...even when i used to gun it alot, it wasnt this bad. Im gonna reset my ECU tonight...hopefully that will help a bit.
As for my area changing the mixture for winter...???? I have no idea. I fill up 93 everytime i fill up. Nothing less.

 

it happens same time when they change for summer blend, your mileage goes to **** for a while...

 

When's the last time you got an oil change? Typically after about 2500 miles my gas goes down to 15mpg but after a oil change I'm back to 20mpg.

 

damn you get at least 15 everytime???? lucky....wish i didnt like acceleration so much.

 

15 mpg sounds great. I'm averaging 10-12 mpg driving in NYC. Even when I drive conservatively I never break 15 mpg in the city. Cruising on the highway I get 19 at best...maybe I need to get my car checked out.

 

I get anywhere from 19-20.4. I live in Tx where the Summers are freakin hot with a/c. I drive it in 7:30 rush hour and 4:30 rush hour traffic back. Have you done your regular maintenance like airfilter/oil/oil filter? How many miles do you have on it?

 

My car is brand new just broke 1000 miles and Im getting 16.2 on the navi screen and driving normal nothing crazy.

 

I've had all of my normal maintenence and oil changes. I really don't know why my mileage is so poor. I am not racing it but man - it seems like when I do gas it you can see the needle move.

 

i hit 400mi on one tank for the first time ever this week

i filled up to a little over 17 gallons. my exact mileage was 402

 

^how the hell did u do that?

 

i got 400 mi out of a tank on my drive from PA to IN.
