I've noticed I'm getting worse fuel milage. My driving habits are exactly the same.

My LS has 64,000 miles on it.

I routinely change my oil, and all other fluids.... however my fuel filter has never been changed. My distributor, rotor, spark plugs, plug wires have never been changed. Would a dirty fuel filter be the culprit?

I can't think of anything else. I'm going to change the oil, transmission fluid and fuel filter later today. We'll see if it makes a difference from teh fuel filter...

 

Try running some fuel system cleaner through it. Injectors may be a little clogged.

 

Which type?

 

Also, what do you define as lower mileage?

 

Def. time for a tune-up plugs cap and rotor and if you got the money wires.....fuel filter as well....

The fuel treatment **** will aid in removing carbon deposits in your combustion chamber.....the deposits over time will soak up fuel decrease mileage.

check your tire pressures too
