My Z still gets the same mileage as was advertised from the factory. 16mpg city/ 24mpg highway. With the original opti-crap and 145k miles. My commute is about 14 miles round trip up and down the Black Horse Pike. I am completely insane on keeping up with fuel system maintenance. Fuel filter every 7k miles along with a pressurized fuel injection cleaning. Startron enzyme ethanol treatment everytime I fill up(which is amazing stuff I might add), peace of mind that the ethanol wont eat up my older non-ethanol fuel system.
