Gas milage way down

01-13-2005, 01:48 PM

I have noticed a huge decrease in my gas milage lately. I used to be able to go 325-340 miles on a full tank of gas but now I am only getting about 275 on a full tank of gas.
I recently had the fuel filter changed about a month ago and a new battery replaced the day after christmas. I am not driving any differently than I have been.
Any ideas what this could be caused by or how to get better fuel milage?

Thanks

o2 sensors, air filter, plugs.

run some injector cleaner through it? seafoam it?

check tire pressure? alignment?
