OP:

Welcome to the forum. The Z is sorta finicky when it comes to fuel economy. I used to get decent fuel economy in the awesome Killeen stop-and-go traffic and I ran my AC constantly to keep from passing out in the 100+ degree heat. I would say that I am getting about 13MPG right now while battling a pig rich condition. I am running a TT kit as well, so it is to be expected. If you can drive over 45MPH for a decent spurt, then you will get good fuel economy. If not, just have fun getting to the speed limit as quick as you can and just deal with it. The cops around here hate it!

if your looking for MPG..... people should not get a SPORTS car...... its called a SPORTS car for a reason... not a sedan. means its meant to be driven differently than the non sport cars of its class lol.

for me im getting 23 MPG on the highway.

just looking at it in the garage will do a few things..... 1. give you whiplash... 2. make it seem like your getting Less MPG.....when parked.

Spent the last 256 miles trying to see what mpg i could get driving like my mother. I'm at 25.4 in 61% highway driving (yes, I calculated that too)

Thanks to those of you who have provided constructive suggestions or information. It's not that I'm so concerned with the mpg that I'm not enjoying the car, the car is awesome! I just have a reasonable concern based on a reasonable expectation set by the manufacturer and their estimates. Clearly other people have the same concern otherwise they wouldn't be responding with their results or tracking their mpg. That being said, I do believe it has some to do with the break-in period. The onboard computer is now showing 18.3 after about 1,300 miles of 70% city/30% highway.

Their tests are basically done with no factors. No hills, no wind resistance, and no tire resistance. Basically they drive it on a Dyno and those are their numbers. If you live in a hilly area, your gas mileage will be lower then us that live in flat areas. This also has to do with lack of torque and needing to rev a little more since the cars stutter a bit under 2500 so its hard to granny shift as it is lol.

the onboard computer isn't always so accurate. I usually calculate my mileage myself based off of gallons pumped and miles travelled since last fill-up. Some times it's spot on but more often than not, it skews high .5-1 mpg for me. I still get 20-22 in mixed driving based off of my own calculations though.
