I have gotten about 27 on long trips. I have gone upto 450 miles before getting gas. A mix of city and highway gives about 20 and city alone gives about 18.

 

13.6 mph/gal
24 mph average speed

I've got to get out more often.

 

trips to the gas station for beer only huh!!! love it

 

i got no more than 360 miles ever. most folks complain RX-8 has fuel economy, but i think my z is worst than RX-8, i drove my RX-8 almost 2 yrs on the same street as i driving now, RX-8 has 23-24, but my z only can go abt 19-20, maybe my z is still new and the rubber is stickier to road than rx.

 

You got 23-24mpg on your 8?!? I've had an 8 and shifting at 3.5k and driving like a grandma, the best I could do in an 8 was 18 almost 19MPG. I would fill up usually around 230miles to the tank. I thought the Z was better, I heard of people filling up around 300+ some at 400miles a tank.

 

i got 280-300 miles per tank with rx-8. sometime even more. but my z 340-360, z feul capacity is much bigger than rx. maybe i need to learn the way to drive z as others drive it with 400 miles.

 

Uhh... are you properly calculating gas mileage? How much you can go on a "tank" isn't at all accurate. How many gallons were you putting in the Z and 8 when you used up a "tank" and went 280-300 or 340-360 miles? Even when you're down to empty, you've got some gas left.

You need to do:
miles travelled since last fill up / gallons of gas used [amount need to take totally fill the tank]

 

i put this in the other post but 400mp tank is not hard at all. driving avg is around 40 mph ( give or take 5 mph) and i havent seen anything less than 400mp tank. but like i said previously, i dont know if the rev high motor gets better gas milage. cause i could see getting close to 500 if i were driving on a trip avg 70 mph. but i feel sorry for you guys getting barely 300mp tank, i think i would be broke.

 

20-21 mpg. My drive is mainly on the freeway going 65-75 mph.

 

I always get over 300 miles on a tank for normal driving with a little spirited driving thrown in. Last I filled up which was yesterday I have about 350 miles on the tank. The computer usually reads somewhere between 21 and 24 mpg.

 

19 city... 30 highway...

 

Right now, 21.4 in the city.

 

My trip meter thingy says I'm getting about 22.4mpg. I reset it with each new gas tank so I can more easily see if I have any immediate dips. I haven't written down how much gas I bought and how far I drove though.

I don't know how accurate the gas guzzler meter is on the Z but on my VW it was clearly on crack, saying I was getting 35mpg when I know for a fact I was getting around 27mpg.

 

Just finished a trip from El Paso to Austin and got 31 mpg, I love tailwinds...On the trip from Austin to El Paso i was at around 28. Still good I think.

 

17-18mpg. All City Driving.

21 MPG, back and forth to work through country roads. 26 MPG, one long trip.

 

75 or so on the highway gets me an honest 26-27 mpg....I drive to my office in S Fl a couple of times a month so it's easy to check. Around town with a little highway thrown in I get about 21-22 mpg. I don't baby it, but it's not 6000 rpm on the shifts all the time either. Best I got on a tank was 442 miles before I broke down (got nervous) and filled 'er up. All highway, of course.

16.5
1 mile round trips

 

20 mpg city/27 mpg freeway

 

I do a good bit of highway driving and inner city to avg about 25-27 mpg and usually get 375-400+ before it starts flashing. Ive gotten as good as 29.7 when i was doing a lot of highway miles.
