mine i think should go 360 if its a 12 gal tank w/ 30 mi to the gallon. i had 325 and the tank is like almost empty with the low fuel light on. i read somewhere that someone gets 420 a tank? will replacing a rusty looking fuel filter help? its got new plugs, wires, air filter ect!. it runs without any missing, it is real quiet too.

 

You really need to calculate gas mileage (miles/gallon) to make comparisons. You also need to mention whether your miles are driven in the city or on the highway. Automatics tend to get poor city mileage whereas their highway mileage is comparable to manuals.

 

In city I get a solid 22 MPG. I've done all tune up, everything I can think of. Only thing is an exhaust leak around muffler area. Pretty horrible if you ask me, my friends Mazdaspeed protege (turbo 2l engine) gets 24 in the city

 

last i checked, it said 29mi to the gal city and highway driving.
