Yep... that's right... 26 mpg on the highway! What the HELL was I doing right?? I drove three and a half hours to Norfolk from Raleigh, and the return trip, and got 26 mpg both ways!! Yes, it's an NA. I SOOO don't drive like a girl, either... lol *(even though I happen to be one)

Now here's the other dilemma. I only knew that because I filled up after each direction of the trip. When I fill my gas tank up, the needle on the gauge goes to Full, but then about halfway through the tank, it drops to Empty. Very few of my dash idiot lights come on for the things they should... so I am not sure it's related. I usually just stick to using the counter gauge and at about 200 miles, I fill up.

Any suggestions on how to fix this problem, please let me know!

Thanks!!

cool.
hey I get fuel economy that high, even driving around town... dont ask me how I do it, you dont wanna hear it... unless you like V8 swaps

the fuel level sending unit is very simple, you can diagnose the mechanical aspect of it very easily by pulling it out of the gas tank for a looksee.

You have a bad sending unit. Mine's been like that for years- goes to full, then at about 1/2 tank drops to zero. I just reset the trip odometer every fillup, same as you...

90% of my mileage is highway, and even as crazy as I (and you?) drive, I still get 26+ mpg.... 26.787 last fillup, matter of fact

Highway mileage in the mid 20's is fairly common. The FD is capable of a VERY wide range of mileage figures depending on how you drive it. My car seems to follow an approximate 5mpg incriment rule:

25mpg - relaxed freeway driving
20mpg - aggressive freeway driving
15mpg - city
10mpg - madman city driving
5mpg - racing at the track

LOL I should write that "chart" down, so I will remember it when I am out and about with my FC.

I get about 31 freeway driving (I'm not a friendly freeway cruiser...) @ about 80mph (4k rpm in the damn GTUs0, around 22-24 for most of my 'city' driving which is usually around 45-50ish. Some cars just like us!

When you filled up
how many gallons did you put in???

since you may or may not have an accurate fuel gauge...

i get about 26 or so on the highway in my 89 TII with a walbro and big injectors and more fuel pressure.

everyone needs a haltech

ha... You guys suck.

I checked about a week ago and got 12.7 gallons with 80% city and 20% freeway...

Obviously that's a lot of red-line time, but still. That's absolutely TERRIBLE. It sucks because I'm poor too, lol.

It probably helps in the GTUs that you can get your 5&6 ports to open up. I noticed that I dont have to give it as much gas if it's around 4k, but then I'm going over 90mph.

The only times I've ever gotten around 26 mpg in my 90 GTU is when I'm crossing eastern washington, just one long straight shot along i90, hell I even managed to get 25 with the AC on.

I routinely get 26 on the highway at 75 MPH and the top down. In fact, just about every RX7 I have owned seemd to get around the same mileage.
