Auto/Standard? City/Highway?

To get accurate readings it's best to reset everying now and again to try getting the average of each trip you take... Resetting everytime you turn the car on will also help you grasp a better understanding of how your econmy fluctuates depending on speed, AC usage, as well as terrain and weather. That's what I do to keep myself up-to-date on how I'm driving...

If it doesn't help any... Deffinately take it to the dealer...

ummm you should get more than 24. unless something went horribly wrong with the 08s. i was getting 27 stock in my 06. with intake and exhaust im around 29.

these mpg are about 90/10 city/hwy also. you might wanna take it to the dealer and have them look. there are so many things that can be a factor in your gas mileage.

my boyfriend said it was because of the leather, etc...that they made the car heavier so it wouldnt get to great gas mileage but i dont think it really could be right?

usually if its a used vehicle,dealers can give 2 shits if the filter is changed or not.When I changed the spark plugs with bosch spark plugs and fuel filter,it made a difference in my gas mileage.You might need a different fuel filter or try grabbing that fuel system cleaner that you put into your gas tank that usually helps out.

Ya it could be your fuel filter for sure. also your oil. running dirty oil will lower MPGs. if you bought it used, the 1st owner may not have changed oil for awhile. just throwing out some ideas.

thats usually the case of a person selling a car,they don't want to take the responsibility of the car so they decide they will trade it in for something else
