Ok, got the car with 16 miles on it, so it hadn't been driven a lot. Given that, we've gone through two tankfulls so far. First one : 34.95MPG and the 2nd tank : 33.4 MPG. Most of that was freeway (about 75%) and city: 25%.
2008 Fit A/T

 

I just drove to Chicago and back to see a game a Wrigley Field... about 310 miles each way.

On the trip up I got 36.5 mpg - and on the return 35.9 mpg.

Nice to get there and have the gas gauge still close to a quarter tank - and just a tad lower after return... even though I set the cruise control on 80+ going thru Indiana.

 

08' base fit a/t

i get between 27-31 mpg city i try to keep it under 4k rpm

kinda week i thought it would be better i guess i will try to sell this piece of crap, about the same mileage as my srt-4 (with a 20g) but with no power , performance or looks to speak of...very disapointed with honda this was my first and last honda, i would say its worth less than 1/2 what i paid for it

 

It's been over a year since I checked the board, but it looks like some things don't change much. There are still people reporting wild single tank results while admitting that the tank before or after was much lower. I made a few posts about this in June '07.

6-14-07 Single tank reading are not proving to be very precise due to fill variances, but they do put you in the ballpark.

6-09-07 I believe that because it is so difficult to get consistent fills in these cars, and the tanks is only about 10 gallons, a variance of +/- 1/2 gallon can cause your single tank MPG to calculate out with a 10% variance. By doing the math over 10 tanks, the measuring variance drops to 1%. In the AT mileage thread you can see that I overfilled one tank resulting in that tank calculating out to 30mpg and filled regularly the next time with a calculated MPG of 37. If you take 1 gallon from the high mpg tank and add it to the low, they both come out to 33.5 mpg, almost exactly the average that I've gotten over 10 tanks.

In another example: you drive 280 miles on a "full" tank. You go to your favorite station and you pump 8.5 gallons by the second click off. You do the math and end up with 33mpg. You drive another 280 miles, go to the same station and pump, but this day the pump is running a little faster, The pump meter is accurate at any flow rate, but with the faster fill, a couple of air pockets get trapped, and you only get 8 gallons by the second click off. Your mpg calculates to 35, yayyy. You drive another 280 miles but since your tank wasn't quite as full when you started, you drive farther into the tank. Back to the same station and pump, running like it was on the first day, and it takes 9 gallons to fill the tank exactly to where it was the first time. Your mpg has dropped to 31, is something wrong? No, your car has delivered 33 mpg the whole time, the normal fill variances are making your numbers jump all over the place.

The Fit has a very long fill tube, which appears to make these variances typical. My 914 has a cap on the top of the tank, you look down the opening and see gas, those fills are more consistent, though a slight slope to the gas station floor can trap air at the other end of the tank and cause a short fill.

The point of this post was to share my opinion that you shouldn't get too excited about high mpg on a single tank, nor should you get bummed if it goes the other way. Keep track over time and you will be able to figure out the mileage that your Fit is actually delivering.

I live in San Diego too and I'm not getting great gas mileage. Same as you. 28-30. I think it has to do with the fact that we're constantly driving up hills, or at I am. Hills kill gas.

***************************
There is some truth to this, but you are missing a couple of facts that would really help. I live high in the mountains of NM (7500 ft), so I don't climb hills, but mountains. I also have a Fit Sport, but 5 speed manual. But we have proven many times that the thin, dry air up here improves gas mileage a lot. On the coast you are sucking in damp, heavy air much of the time...and that creates not good gas mileage. But I believe you could also really improve the situation by increasing your tire pressure. I run at 45 psi, and the ride is very good for us. I have never taken a long trip with our Fit, mostly town and hwy miles.... and we fill up twice per month. But we are consistently getting over 40 mpg, with the highest being 43.5.

Pump up your tires....you will notice a big difference.

 

I guess I will try two idea's. try driving 65mph. raise tire pressure to 45psi. I will let you know how I make out.

 

Hey everyone - especialy ewdysar - THANK YOU! The info was really great and is putting my mind at ease a bit. It's very hummid in Austin and we've had our hottest summer in 85 years, so it's always AC on for me. I'm a girly girl, can't arrive sweaty! I had my mindows tinted the Monday after I got the car, but it gets hot in there - much hotter than the RX8 with black leather seats, so I run the AC on 2 or 3 a lot. And, even if I only average 29 mpg, it's still so much better than the 16 or 17 with premium fuel (required) in the 8. I still yearn for those high numbers...but I think I'll just be happy with my beautiful blue fine Honda ride as it is. Though I still hold out hope for higher numbers this fall and winter.

Thank you SO much again for the info and the time!! )

 

I have an '08 BBP Sport AT. It had a full tank of gas when it was shipped to me, but 9 "mystery miles" that the dealer couldn't account for on the odometer. I wonder if the driver of the truck didn't take it off and tool around in it...but irrelevant..

I filled it today for the first time (a whopping 8.9 gallons!! Less than $30). According to my calculations, I am getting at most 25 mpg, mostly city driving. I do run the AC all the time, and we have the 10% ethanol blend gas, which does cut mileage some.

That's not bad mileage, but I'd love to see 30 mpg in the city - how can I improve my numbers?

 

I averaged 38mpg over 426 miles - two 5.5 gallon fill ups. (Single one day 6 hour drive).
All highway with some traffic - average speed for the trip my gps says 76.3mph.
Temperature range was 85 - 91 degrees.

 

Tire pressure - go over 32psi. Max tire pressure the dunlops can hold when COLD is 51psi. Run around 40PSI cold all around. You'll notice a difference in MPG.
Keep revs capped at 3500rpm, speeds maxed at 70 highway, and let up off the gas early if you know a light is about to turn red.
25 is not bad in the city especially with A/C. most of my City MPG's are about that. I rather not drive too conservatively. haha.

 

Just did a 3 week run to Arizona and back through Utah/ Idaho...4475 miles. Kept the throttle controller on "eco" but drove 70+ mph most of the time. Averaged 33.7 with a high of 43.6 from Flagstaff to Kanab. The low was 27.9 from Sedona to Flagstaff with 4 adults and a big cooler. Not too bad for an AT...

 

Thanks a lot! I'd seen people talking about upping the pressure in their tires, so I'll do that right away. I'm not going to nurse the car and drive like grandma for 3 mpg, though. If we are talking 30 v 24 mpg, then I might slow down all the time. I never speed but I haven't been watching the tach either. And I don't race up to lights and then brake like a crazy person. So...hopefully my mileage will improve, although I'm probably done with the break-in.

I think our gas formulation sucks too.

 

Zippy and I did our annual CO to OH and around the midwest trip again this August. I did not make it a mileage run either way - was tight on time. I was loaded down with about 300 pounds of gear. Average for the trip was 36.9 MPG.

Last weekend I did a central CO to WY trip. Two of us, 175 pounds of gear. Ran the air on the way back. Tooled around in first gear on and off both days at the event. Did keep it to 72 and under on the highway.

38.7 MPG average.

Tuesday did a run over to Taylor Park to meet friends and do a dirt bike ride. 125 pound trailer, 200 pound bike, 70 pounds of gear in the back. 72 and under again, no AC. 34.3 MPG.

Yea, I'm pretty happy with Zippy

 

ive had our fit for five months and from the second tank full ive kept up with my mileage every fill up for 5 months and i have never seen over 26mpg except twice i got 28mpg. i have a 08 AT and drive city all the time and have yet been able to take it in a highway drive to see if it gets better. the longest between a light or stop sign i have is like 6 miles.

 

Do you have the ethanol blend over there? We do, and our mileage sucks. And has, ever since the stuff was put into the gas. I hate it. I'll take my corn in tortillas and whiskey, thanks, not in my gas tank.

 

hey thats totally normal for city driving. certainly within epa city range specificiations.
It's just somewhat sad civics do better with mpg.

 

yeah tell me bout it, my hatch with swap, intake, headers, exhuast is getting 28 to 31 mpg consistently...filled up this morning and adding it up and got 31 mpg this past fill.

 

All my info is from meticulous use of my scangauge I bought months ago. My car has a sid SRI and megan axleback. Using normal dyno oil and 87 oct gas from Costco and Chevron. Most of my driving is on pretty flat streets, with the only real hills and inclines appearing when I'm not on my daily driving route from home to school/work and back.

The highest whole-tank-mpg I've gotten so far is 32, and that was with around 85% highway driving going from LA to San Diego and back. The average I get (50/50 city and highway) is around 26-27, and I've had a few tanks that were 28-29. I shift in S mode, and I usually shift up around 3200-3500 rpm, and never push the car past 30 TPS according to the scangauge. When I try my hardest to keep my rpm low and throttle position low (<30), I still get around 26-28 mpg. The variance is very random and no difference in driving technique produces 26 or 28 mpg consistently. I have noticed that city driving absolutely kills mpg, mostly due to the fact that (at least in my car) I don't hit the "sweet spot" of 30+ mpg till I'm at around 40 mph and no longer accelerating.

Take hills, slow zones, and having to stop every 3-5 minutes at a red light, and that's alot of time spent in gears 1-3 below 40 mph just trying to get up to the "sweet spot."

Usually I hit an average of 32-34 mpg when I'm traveling on a flat stretch of highway at 70 mph, but all that is negated by the fact that I have to spend so much time in the 0-15mpg range during city driving.

Here is what my scangauge shows per gear & rpm range while accelerating during what would be a normal daily drive, all at around 25-30 tps:

1st gear : 0-5 mph : 0-3000 rpm : 0-7 mpg
2nd gear : 5-20 mph : 0-3000 rpm : 7-10 mpg
3rd gear : 20-40 mph : 0-3500 rpm : 10-20 mpg
4th gear : 40-65 mph : 0-3500 rpm : 20-29 mpg

I shift into 5th when I'm at 40+ mph in the city, or around 65 mph on the highway, at which point in both cases the mpg starts to even out around 32-35 mpg in cruise control, no longer accelerating. So this means that every time I stop at a red light, I have to go through the slow process (due to keeping a light foot/low throttle position, shifting at low rpm) of moving from gears 1 through 4, from 0-40 mph - that long stretch of gears 1-3 where I am stuck with the very low mpg before I can turn on cruise control in 5th gear/40+mph where I finally start getting good mpg.

Also of note is that according to my scangauge, taking rpm up to 3500 instead of 2500 makes no difference whatsoever to mpg. In fact, shifting at 2500 would just make the car bogged down and so slow to accelerate that it has to spend more time in the low mpg zone of the low gears/low speed that I'll be using more gas just trying to get up to the higher gears/speed.

I still have no idea if there is some kind problem with the car that is resulting in the huge gap between my results and the average driver reporting in this thread, but at the least I know that I can get great mileage on the highway. Is this normal to have such atrocious fuel economy going from 0-45 mph at a slow and steady climb in speed (<30 tps, <3500 rpm per shift)?

The funny thing is, when the question of why some Fits are getting low overall mpg while others are getting much better results from say, JUST city driving, the answer from those who aren't having mpg problems is that it's all about technique, and that it's due to a lead foot. Well, after months of driving around at 20-30 tps, sticking to 2500-3500 rpm shifts, I've seen absolutely no difference in the resulting mpg of what have been pretty consistent drives over the course of months. The fact is, to have an even lighter foot to hit 15-20 tps means to pretty much not touch the pedal, considering the Fit idles at around 14-16 tps. The car is slow enough as it is catching up to the speed limit using <30 tps, <3500 rpm shifts, I doubt there is a more efficient and extreme method that others are using just naturally for controlling an even lower throttle position, shifting at lower rpm, while actually driving instead of rolling forward. If I start using >30 tps, I find that my mpg starts to suffer dramatically while not getting that much greater response and power from the engine.

By the way, before anyone points out that I'm using a short ram intake - I've done plenty of experimentation with the intakes, stock vs my sri - and the sri beats the stock in both mpg and performance. I've driven at least a few thousand miles using each intake, resetting the ecu every time I've changed the intakes out. The stock intake lacks the oomph the sri provides at the lower gears, and it actually killed my mpg I was getting with the SRI; highway mpg was down by 2-4 mpg travelling 70 mph on a flat stretch, and city mpg was down around 1-2 mpg throughout the rpm and mph range. There is nothing to be gained from using the stock intake from what I've found in the 13,000 miles I've put on the car so far, not to mention that my car struggled up hills that I could manage with the SRI.

Now one thing of interest is that I recently installed a WeaponR street header and reset my ecu. After 100+ miles of driving, my scangauge reports that I have an average 29-30 mpg so far from around 60/40 highway and city driving. While I am used to seeing my average mpg just keep going down and down while driving around the city (on every tank I've had since I got the scangauge, I'd get around 32-35 mpg from highway drives, then at the end of the tank the scanguage reports an average mpg of 24-26 due to city driving killing overall mpg), I've actually been able to keep the average mpg from going down the way it usually does while city driving. There is definitely increased torque and response in the lower gears and rpms with the header, resulting in less time in the mpg-killing-zone before I reach that "sweet spot" where I start hitting 30+ mpg. I'll have to see if this trend will continue, but it's looking pretty good so far.
