As you all know, gas prices are shooting through the sky right now...what are some ways I can improve on my gas milage?

last year, i got around 270 miles on about 9-10gallons of gas, this year i'm down to 240 miles on the tank. What is going on? what would i need to replace to possibly help me improve my gas miles?

i have no mods on the engine at all and i shift between 2.5-3k rpm. my hwy and city driving is 50/50.

can anyone help out a car noob?


Thanks a lot
Tommy
