my mileage has increased since i adjusted my valves....
averaging in the 40's on the highway and high 30's in the city.

my exhaust valves were half the lash they were supposed to be.
either the factory has QC issues or the valves recede into the seats real fast!...check those valves...it ain't that difficult!

Retire to where there isn't much traffic. It's over 30 miles from here to the nearest traffic light but most of my errands are in closer towns.

 

How many miles do you have on your car? Adjust by replacing shims? (I can't believe that Honda would still use screws, but . . . )

 

With 47,887 miles on the car, the lifetime average that I have recorded is 36.22mpg. The realisitc average is a tad bit higher as my snow tires throw off the odo/speedo by about 2-3% for 1/4 to 1/3 of the year. Average is probably closer to 37mpg.

no shims and thankful for it...yes! conventional valve train. four valves @cylinder, meaning two intake, two exhaust. great set up on the cam sprocket to let you know when everything is aligned.
there's a wonderful pictorial in the maintenence thread.

at the time of the adjustment i had about 52K.
should've done it at 24K!

cheers.....

Not much traffic where I live. Don't know if I'll ever retire. I'm OK with 40 mpg. Beats most. Sounds like you live a little more rural than me - but such places exist within a couple hours drive from here. 60 miles/22 lights for my twice a week work commute!

 

So far I have gotten a solid 37mpg on the tank. 60/40 city/highway driving
Best I got was 42, the worst I got was 34. (13'TW MT)

 

Another fillup, 42.7 which makes that single 39.x fillup an anomaly. At 1,675 miles the total avg is 43.52. I even hit the rev limiter about 8 or 10 miles before getting gas. (I could no longer follow the Subaru doing 30 in a 45 zone then 45 in a 55 zone.)

I've been doing more reading about gas formulations, and it's not that we have "winter gas" but more like we have "summer gas". From June 1 to Sept 15 -- which are high-ozone months -- the EPA restricts the components of gasoline that are most likely to evaporate and make low-altitude ozone worse. I know there are other changes and some state regulations so the formulations can change any time of year, but the big drop should be mid-September when the most volatile parts (that coincidentally have more energy) are removed.

All this means that I haven't ever had real "summer gas" in this car unless it was put in before my first test drive.

 

40k + on my Fit. Averaging around 35 mpg. Sometimes more, sometimes a slightly less. This is driving in metro Atlanta. Commute is 70+ miles a day. Couldn't be happier. Can get 40 + mpg on long highway runs.

 

I got my worst tank (37.5) followed by my best tank (42.5) the last couple weeks. I had a family issue 2 weeks ago and I think I was not focused on my driving like I usually am. Then came rainy, cool weather the next week. Same exact drive for 90% of the miles. Interesting.

 

500 Miles on the car so far. ~36MPG with about 20/80 city/hwy. Will probably go down once i get more lead footed but driving her easy since she's new.

 

Only about 300 miles on my new Fit, but I'm getting around 27 right now. I work 3 miles away so it heats up about half way to work which heavily effects mileage. Went for a drive today and averaged closer to 30.

 

I think that mine takes a bit longer than 3 miles to get better mileage. Your light may turn off, but I think mileage improves for several miles after a cold start.

But WELCOME. (Been too long since I was in Idaho, but great mountains and lava. Do I remember a meteor crater?)

 

My mileage display is sometimes high and sometimes low. My odometer is correct and I enter my gas purchases in a spreadsheet.

That spread sheet also has a "rolling 3-fill average" to help smooth out the lumpy MPG figures caused by filling the tank to slightly different levels of "full". I started this for long motorcycle trips where the tilt of the concrete around the pumps can cause "full" to change by 10% for a small gas tank. The rolling-3-fill average is the sum of the last 3 trip odo mileages divided by the sum of the last 3 gas volumes.

Today I decided to look at a rolling-3-fill MPG display. I didn't record the MPG display's "guess" for the first few fillups, but then started adding that number to the receipt to compare with what math said. But I do have 7 displays recorded that allows for 4 3-fill display averages.

The rolling-3-fill MPG display average is consistently 1MPG above my calculated rolling 3-fill average.

I cannot say that the display is great, but I know that each fill can introduce an error into the calculated MPG. The display may be better than I've thought.

Is this useful? No.

Does this make the MPG display work better? No.

Why would anyone spend 20 minutes looking at this? I just don't know.

Why write it up to post? I really don't know.

 

40 mpg according to the meter.
Realistic probably 39. Hwy 80/20 city.

 

Winter is here so my is steadily dropping with start ups and running the car while cleaning off both cars. Down to 32.5mpg versus 32.9mpg a couple of weeks ago will probably go down to 31mpg as winter progresses.

 

My commute to work this morning. Chevron 91 + Filthy K&N panel + 20% oil life + balding 195/60/15 Falken 512 @ 31psi (I haven't filled them up since it got cold and lazy lately).




4 miles streets with lights, 26 miles of highway @ 65mph average with light traffic and a few 3rd-4th WOT left lane passes @ 80mph. No hypermiling trickery whatsoever.

Just posting because I got to work and was surprised because I wasn't trying.

 

I am getting average 33 mpg. Rural roads, 20 miles commute plus in town driving.

 

Over thanksgiving weekend, my family and I drove over 1,850 miles in an auto GE8 Sport. Vehicle was 80% loaded and we drove with the defrost (automatic AC) on the entire time. MPG was ranging from 42 to 38 the whole trip. Loving the MPG compare to my previous Ford SUV but I do miss the size, power and comfort of the larger SUV

 

Just cracked 10k miles. My average fuel economy over that time is 33.5 MPG. Best mileage was clocked in the summer at 37.5 MPG, worst was 28.6 MPG during the spring, mostly short trips in city driving.

I'm very pleased in general with my mileage, but a bit disappointed when comparing to other Fit drivers who regularly clock high 30s (a rare occasion for me) and even 40s (never happened on my Jazzberry). There are a couple of theories as to why, one being I have an unfortunate habit of taking short trips, big hypermiler no-no, another being my propensity to drive 75 mph.

This is getting a little long, but I was wondering at what point most drivers here are shifting. I was originally sticking to the OEM manual recommendations (1-2 at approx. 15 mph, 2-3 at 27, 3-4 at 35-40, etc.), but that seems a bit sluggish not to mention spends more time accelerating, less time cruising. Lately, I've been shifting up out of first around 3500-4000 RPM. Any opinions on whether this is adversely affecting fuel economy?
