My first tank was identical to RX-8-u-up's - 16.1 in town. My 2001 Millennia S got 18 mpg on the same drive pattern (work) and with AC running. The other cars I looked at - 350Z, G35 were very similar to the RX and it is OK. My greatest concern is that we get the Horsepower/Performance issue resolved.

 

My first one isn't complete but it's HORRIBLE! Does the top half go faster? I went 150Km on 1/2tank or 30 liters!

Of course I haven't been going light on the car (not too hard) but shifting at 5K instead of 3 and shifting at 7 k a few times :D

 

If you think it's going do down fast the first half, it will go down even faster on the second half.

Watch how fast the miles go up. Isn't that car a blast to drive...and drive...and drive?

 

220 miles at first fill up, 14.1 gallons. 15.71 mpg. lots of showing off on regular roads the first weekend thru twisties and such. cruising between 4 and 6k most of the time on highways. ac on most of the time. i have heard peopel say you get better mileage with the windows closed and the ac on than with the windows open and no ac, is this true? there will be more highway miles on my next tank, so the economy should be better.

 

Third tank check in...Jeeeeze it's been a while since I've been to this board, too much work lately got to pay for the car.

Anyway, here's my 3rd tank:

255.0 miles using 13.439 gallons = 18.97 MPG.

And for good justice, here's a re-cap of my 1st and 2nd:

1st: 230.9 miles using 12.194 gallons = 18.9 MPG.
2nd: 249.1 miles using 13.343 gallons = 18.7 MPG.

The best part is that the 3rd tank was ALL "city" (not really stop and go city, but not constant speeds on the highway). Plus this tank I've been bouncing above 6k a lot more frequently and have hit 7-8k a couple times here and there.

I think some of you guys doing really badly are just either always shifting a 7-8, or holding RPMS above 3k for much longer than you need to. I find that just about every gear shift around 3-4k will bring you down around 2-2.5k. If you are going to be at a certain speed for more than a couple lights, you may consider downshifting at around 3-4k to stay below 3k (where the 2nd injectors pop open) if at all possible.

Anyway, happy driving everyone!! I think I'll continue keeping track of this for a bit...just for my own edification. Although, it's funny, every time I look at the gas gauge and then start to fill up I think, damn I've driving this thing harder this time, I think my MPG is going to be ****, and then the pump stops at around the same gallon mark as the previous tank, but I've gone just a lil' bit further. :D, break in is almost over (I'm at around 750 miles), so then I'll see what the real story is once I start unleashing the power a bit more. But as I've said many times, I'm doing better than I did in my Z28 with similar driving, so I'm happy.
