my legacy is 4wd 2,2L 5 speed and
i would like to know how many MPG to expect
and also is the fuel guage really wacky on anyones car.
mine acts odd seeming less full when in motion thanks

your mileage is 21/27 city/highway

Our gas tank is a 'saddle tank', which means it sits ontop of the driveshaft, so the gas gauge is always a bit wonky, especially near empty.

I get about 28 with my 93 with 2.2L AWD and 5sp manual. I've never really had any issues with the gauge acting strange.
