I know this topic has been asked over and over but I am concerned about my fuel economy. I've done some searching on this sight on gas mileage. Some of you guys aren't really concerned with it because it might not be daily driven cars. I drive my car to school everyday and usually is about 25 miles each way. I think Im only getting 15-15 1/2mpg. That is only highway and very seldom I get into some minor traffic. My Z is completely stock with no extra weight in the rear. I've done tuneups at school and inspected my plugs and coil packs and they are ok. Although I do smell a little gas at times but I cant seem to find a leak. Is there a common fuel system component which tends to leak on the Zs? I think I should hook it up to an analyzer at school so I could see the emmisions. Any suggestion please. Thanks.
