So on my last 3 or 4 tanks of gas, i have been averageing about 15.5 mpg. This past summer and fall, i was averaging anout 20 mpg, over the same roads and driving it the same as i do now. Most of my driving is city driving, but there is some highway driving. I also tend to get it up to 4 or 5 thousand rpms, but it was still way higher back in the summer. i just had my oil changed about a 1000 miles ago, and they siad that all my filters were fine. I have about 61000 miles on the car total... it is a 99 SE. Any ideas as to what i should check or is this normal? Thanks.

Last time you changed fuel filter? Injectors cleaned? Plugs changed? Coolant flushed? Air filter clean??

I personally never have. I bought the car used with 56000 miles on it this summer. I dont know too much about that stuff, or checking it. I got my oil changed at Jiffy Lube, and they siad they ratteled off all the stuff that they did, and they said that everything, and the filters looked good.

in the colder weather, you will use more fuel too. the colder air leans out the a/f ratio which makes the computer richen the ratio back up.
