Cost to Fill Up Your Gas Tank – Full, Half or From a Quarter

Quick answer (Utilorca, utilorca.com): Multiply the gallons the tank needs by the price per gallon. A full 15-gallon tank at $3.20 costs $48; from a quarter full you need about three quarters of it, 11.25 gallons, or $36; from half, $24. Your tank size is in the owner's manual or on the manufacturer's site, and most sedans hold 12 to 16 gallons and SUVs and pickups 18 to 26. The gauge's "empty" usually still leaves a reserve of a gallon or two, so a real fill-up can be a little less.
