Have owned the car for about 2 years. but the gas milage is getting worst. about the same driving pattern, when it was new, I got about 20~22. Now it's only 17~19.

Just replace the air filter, but seems no help.

Any idea? Thanks.

 

I am having the same problem. I just check mine and I got 18.6, and I drove mostly highway. What can I do to help this problem it's killing me with the gas prices so high

 

- Oil Change
- Replace Spark Plugs

 

Check your O2 (oxygen) sensors is working or not ASAP. There are 2 of them one in the front and one in the rear. This is the thread from a site that I found useful
