Hey guys, I know that you have all probably been pretty anxious to participate in my poll, but If anyone has a second to help me with my probs stats class it would be awesome! Thanks guys! Just pick what best fits the gas mileage you most often get..thanks again.

 

Are we talking about city, or highway driving here?

 

I agree, you should specify which it is. I went ahead and put 18-20 since thats what I get in normal mixed driving. I can get to 26-28 with solid highway, though, or at least I could with my old motor. I have yet to see with the one I just dropped in.

 

i get less then 12 lol

 

less than 12!!!! help me!!!!

 

if ur getting below 12 mpg relatively stock u should be replacing ur o2 sensor and seeing if ur plugs are still good

 

im not stock hehe

 

If your getting less than 12, then the O2 sensor is the least of your problems.

 

> You were able to get 26-28 mpg at one point. That's pretty good for an FC.

> I'm getting about the average... mixed 18-20 city, like you pointed out. And slightly higher on highway... roughly 21-24 mpg.

> I have a new TII now that's on Premix and I haven't calculated Mileage but I'm rougly getting 14 or 15 MPG right now. It could be higher but I've been stomping on it lately. What's the average mileage for a TII on premix?

 

Average city driving for me results in 14.5 mpg in the NA rex. Interstate driving gives me 22mpg, but I have a crappy old wore out automatic.

The TII on the other hand was getting 16 and 17 in the city...... when it was running.

 

I get ~24 highway doing the speed limit without the AC (Windows down, sunroof open).

 

Yeah, it got pretty good gas mileage with the old engine. It was freshly rebuilt (10k miles) when I got 28 MPG on the highway. It was solid interstate cruising between 70 and 85 with the windows down. In "spirited" back roads driving, which is the main other way I drove it, I got between 18 and 20 mpg.
I am curious about what the milage on my new engine is. While I am saving for a proper rebuild I dropped in a junkyard s5 motor with 95k on it. I have put about 100 miles on it since I got it running, but its down at the moment while I am redoing the wiring harness. I hope to have it running tomorrow or Saturday, so I will post my mileage once I get it.

 

Im not completely sure, but I guessed 16-18. I was getting slightly better when I first got the car. My car is a bit out of time right now and have some other small issues. Plus my O2 sensor is not working at the moment. Wire where it goes into the sensor has wiggled back and forth so much it it just hanging on by a strand or 2. So I highly doubt it works

 

I am mostly just interested in average fuel economy, highway, city, modded, stock, stick, auto, it's all valuable as far as my stats assignment goes! Thanks alot guys!

 

For the record, I had a large streetport and a RB collected header for those fuel mileage figures.

 

I just got less than 12 mpg. I did about a 50 mile run in almost entirely 2nd gear up through some mountain roads, RPM about 4000-6500 the whole way. I calculated it out to 10.8 mpg, and that includes the freeway trip home at 80mph. Is this normal for that sort of driving, where I was constantly using the compression braking of the engine and punching it coming out of corners? Its a completely stock 87 N/A GXL.

 

you didnt see htat mythbusters episode, did you.. you get more mpg with the AC on, windows up at highway speeds

i got 22 mpg in the TII last trip to cola i made, usually 16mpg city

 

i saw that

 

My N/A I can get as much as 35 on the highway, but my TII with a TO4B and 720 primaries and 1000 secondaries is well under 12 MPG. (but damn it's fun to drive)

 

 

+1

 

you guys are all negative nancies. he could have a Honda powered FC with awesome mileage.

the NA gets 17-18MPG city and up to 25MPG on long trips.

the TII gets 15mpg(i have to work out SOME bugs still) and 18MPG Hwy.

I'm glad the TII is getting some TLC the next few months because Gas prices are ridiculous right now.

 

i rarely get above 20 mpg in my N/A. but its a mix between city and high way driving every week.
i avg. around 18

 

When I was N/A I got 18 city 22 highway. Now when I got the TII swap done im getting around 14 city 17 highway. But the car is running extremely rich im pretty sure the O2 sensor is cooked. I did however get 25 highway during breakin with no boost!

 

so.... you swapped in the geo metro motor? thats hardcore!

seriously, my old 86 gxl the most it ever got was 28hwy

now... my 90 GXL/GTUs gets 12 or less, no matter if its highway or city... somethings horribly wrong lol. Motor needs a rebuild. 215k on the stock OEM never rebuilt motor.
