To the OP -- your mileage certainly sounds low to me. The lowest I've ever had for a tank was 22.4 mpg, and I average 24.4 mpg. But as everyone else has said, there are many factors. Also, I don't recall seeing a thread for a specific AP1 problem that caused low mileage...
I like the suggestion of filling up then going on a highway ride of at least 60 miles (preferably more) at ~60 mph, then refilling right after you get off the highway to see what you're getting. That's a good way to start tracking your problem IMO. Good luck

top down decreases mpg by a small bit, but most of all give yourself time to get used to the car. at first you are enjoying the constant rush of the setup but over time you will ease off and mileage should improve unless there is something wrong with your car.
my ap2 gets about 22-23 average with over 28 on longer trips, keeping in mind my mix is about 50/50 freeway blvd and there is altitude where i live, yes hills make a difference vs all the time flat land.
i am ok with my mpg i did not buy the car for the best mpg in class althought i think it has that going for it as the others have mentioned.

In my first month of ownership I would be surprised if I did better than 10mpg With all the enjoyment of flogging the car all over the place and revving up to redline constantly until the initial thrill wore off, I didn't bother measuring how efficient I was being

[QUOTE=Disgustipated,Jun 2 2010, 01:28 PM] It depends on how fast you're going. If you're driving over 60 mph with the top down, the drag increases exponentially. So city driving with the top down means there's a minimal, perhaps nonexistent decrease in gas mileage. But once you hit the freeway and speeds go over 60 mph, you're gonna start feeling the effects of drag on your gas mileage.
My advice is to roll up your windows all the way with the top down if you have to go on the freeway. If I know I'm only going on the freeway for a brief amount of time with the top down, I'll roll up my windows to minimize the effects of drag.
Also, don't drive with your windows down (top up) on the freeway. Use your air conditioner instead. The MPG hit due to drag with the windows down is much higher than using your A/C.
I always laugh when I see trucks/SUV's going 85 mph on the freeway with the windows down.

I've always been told this as well. When I had my sentra, I made a trip from San francisco to LA. I had my driver window down averaging about 35-36mpg, with three passengers. About halfway through I turned on the AC and window up, and it quickly dropped down to about 30-31. Turned AC off, and window down and it went back up to 35-36.
Keep in mind I-5 is a flat straight road, temperatures really don't change on that stretch, no traffic, and kept cruise control on through the stretch @ about 80mph.
I'm not saying it's not true, but my experience(s) seem to say otherwise.

The physics of having the windows down can be demonstrated with a couple of examples. Look at a parachute or a plastic bag. When moving at a high enough speed, they fill up with air and this slows them down. The same thing goes for the inside of a car.
Modern cars' A/C compressor doesn't use up a lot of gas on low settings. So as long as you're not blasting it, it should have a smaller effect on gas mileage than having the windows down.

Another thing to note: on short trips, going 75+ is just a huge waste of gas. If you're only going 20 miles, depending on how much is freeway/city, you're only going to get there 1-3 minutes faster on average (I factored in a low amount of stops... which is being optimistic) going 80 vs 65. But you'll use quite a bit more gas. I try to keep my max speeds around 70-75.
Except when using VTEC, of course.

yup i just made 355miles to the tank and still had 1 bar left when i put gas in. this was with 3/4 of a tank hwy mountain roads going between 40mph and 70mph frequently. the last 1/4 tank was city driving
