BUICK REGAL GAS PROBLEM

1998 Buick Regal • 156,000 miles

Over the past year my car's gas mileage has been slowly getting worse. Right now its getting 20.3 mpg and the car is starting to chug when I reach appox. 50 mph.
I had the spark plugs replaced last summer. If I replaced the fuel filter and started putting real unleaded gas in, would that fix the chugging? Would a transmission fluid flush help? Any other suggestions?
