I got my 2003 TL-s last august with 49,000 miles. it now has 61,000. The only thing i've done to my car is oil changes( fully syn. about a month ago). I want to mantain my car better but I have no idea what to do. im getting terrible gas mileage.

can anybody give me some pointers on what parts I should replace. spark plugs, filters etc....

 

Hate to say it, but do a search. It's been discussed many times before; quite recently to he honest.
