I need to get mine out on the road and open it up a little. I wish I got the kind of mileage you guys are getting. I'm getting 13-14 strictly in town driving, car really isn't all that broken in yet though.

 

 

har har ... that is my mileage.

11-13mpg
but that's probably just cuz of the way i drive.. pedal to the metal from 0 to 150mph ( i get to ~130mph on a daily basis! )

 

Mine's a daily driver. I drive 8 miles one way to work with 17 signal lights and I average 14.5. I do 75-80 when I go away on some weekends to Orlando and I average 23-25 highway. That's a drive of about 200 miles.

 

Understand about milage.

I have 6 months and 4200 miles on the pig.

City drives produce 13 to 15 mpg.

Highway drives 60 to 75 mph produce a 21 to 23 mpg according to car computer and has been verified at the pump with pen and paper.

 

I get about 18 combined, best I've seen was 25.8 on a trip, highway. Usually cruise @ 72 or so on highway.

 

I get about 14-16 in town (los angeles) and anywhere from 22-25 on the free way doing 70-80. Auto trans with 4.10s. I have probably 12k on the car

On my trip home from Los Angeles to Louisiana and back, I averaged probably about 24mpg, doing about 75-80, sometimes 85.

 

That's realistic....
I live in FL so most of my driving is on the highway. I normally get about 22mpg mixed hwy/"city" driving. The best I've ever gotten was 27 on a long trip.
However, I worked up in DC last year (THE definition of "stop & go" traffic) where my mileage plummetted to about 14 mpg. And that is all reasonable driving. I'll get on once in a while but every day.
My point is that what one person considers city/stop & go traffic may actually be an exaggeration.
Hope that helps.

I have Saleen S/C with JDM 3.6" pulley @ ~8#: My Avg Mph is currently 29 mph with 70% city / 30% highway and MPG is 14.6

 

I consistantly get 18mpg and that's running at about 27mph average... mostly city driving. The farthest highway stretch I've had it on is about 30 miles, averaged just over 22mpg, but I'm pretty sure that would be higher on a longer, more consistant stretch of highway.... can you say "Road Trip?"

 

The longer you sit idling without the car moving, the worse your avg. MPG readout will get. I was stuck waiting in line at the Canadian border two hours last Labor Day weekend. I sat and watched the mpg number drop. By the time I got going on the highway again my avg. mpg was 11.1

The best mpg I ever got was when I made a 10 mile trip down a road with no traffic at all, doing a steady 40 mph. I reset the computer as I left my house and by the time I reached my destination 10 miles away it read 38 MPG .

 

90% interstate driving at 70-75 mph = 23 mpg average. Pretty normal I'd say.

Maybe I should install a SC and some 4.10s to improve my mileage.

 

I avg 12-14mpg. Most of my driving is below 40mph in traffic and city driving, plus I hammer it pretty hard all the time. I'm safe, but impatient. If the lane's open, I'm goin', and green tells the guy behind me that I've already left.

Highway, though, I do much better. Last trip I took, I averaged 35mpg, doing 65-95mph over 200 miles. Big engines usually do better on the highways anyway. Once you hit a bit of traffic, though, yer doomed.

I decided midair refueling was the only way to go, so I did a little mod work on the roof to solve the problem:



I keep calling the Air Force, but they won't cooperate for some reason...

 

My gas milage went up big time after I put a few thousand miles on it. I typically get about 25-26 on the highway going between 65 and 75, and around 13 driving in the city in stop and go traffic.

I have the manual 5spd with the stock 3.55 gears.

 

I think part of the reason that all these people are getting poor gas mileage (only around ~25 tops on the highway at 60 mph) is the tuners.

I had a Predator, and the BEST I got was 25 mpg cruising at 60-65. This, combined with the on/off switch-like throttle response, made me go back to stock. My mpg went back up to almost 28 at 60-65 after returning to stock.

 

I like your ingenuity!!!!!

 

just for kicks once, I reset my computer MPG at the top of the mountains, and when I got down to the bottom it read over 68 mpg

On the subject of MPG, has anyone double or triple checked the computers estimates with raw figures over a period of several tanks? I'm not so sure that I completely believe what it reads. Not because I think it's off base or have any reason to not believe it, but just because I guess I don't understand how it's determining it's results.

I don't ever check my MPG on paper (I'd buy an import if I was conserned with my mileage) but I do take note of what the computer reads out every time I reset the computer and trip odometer after a fill up.

 

Error404: I've double-checked the computer for the last 15 fill-ups... Never been off by more than 2-tenths vs pen and paper calcs... most of the time, it's right on.

 

The trick is to either leave the computer alone and let it get enough data, or only trust its results in a specific scenario. (ie - if you reset while cruising at a constant speed, you'll get an okay number of how you're doing right then, but if you hit some traffic or whatever and your fuel consumption profile changes, the number gets...misleading).

The longer you leave it alone, the better it gets. The periods of good fuel economy (highway/cruising) will average out with the bad (city/hammering).
