Default losing in MPG

As u guys aware, the gas price is kinda expenisve nowdays, I just don't understand why my 98 LS can only make around 300 miles with full tank means 300 mile for 20 gallons? B4 it's around 360+ Do I need to do the fuel injection in order to improve my gas range? BTW, I did floor it hard pretty often but never experience such losing MPG before!!

Well,

300 / 20 = 15mpg
360 / 20 = 18mph

I typically get 19mpg combined highway/city average. These cars ARE thirsty if you use the power frequently. 300hp and a heavy care requires GAS to go fast

The difference you state is not large if you were doing a lot of playing with that tank.

Other than driving style did you change anything else? Exhaust, tires/wheels, torque converter, etc?
