DX/LX/EX: Your Gas Mileage

[blitz911]

highest is 26mpg and lowest is 21mpg. mostly all city driving. i have an auto ex. but i hope it'll go up after i do an oil change. i'm at 30xx miles right and the oil reads at 50%.

[yeppi]

how do you calculate your gas milage?

[grc0456]

Worst = 31.5mpg
Best = 39mpg

Mpg = miles driven divided by gallons of fuel used

Method = 1) Fill Tank, 2) set trip meter, 3) drive car, 4) fill tank again, 5) note miles on trip meter, 6) divide miles on trip meter by gallons used on second fill up

Wow, I'm shocked to see that most people aren't getting much better mileage than the Si

[bodydraggin]

im averaging 24 mpg all in town and sorta hard driving.

[TrekRider]

Average mileage 36.5
Best mileage 44.3 (85 mile average)
Worst mileage 34.6

'06 LX Sedan

[Intrepid175]

My local driving runs around 40% highway. I'm averaging between 31 and about 33.5 mpg with that depending. My low tank so far is 30.5 and the highest I've gotten on a trip was 39.9 mpg, obtained with a nice tail wind the whole way, just couldn't quite squeek that last tenth of a mpg.

BTW, '06 EX sedan, navi w/MT

[Honda2k7Ex]

Im getting about 22 miles per on average. Really piss's off since the main reason i got this car was for the gas mileage

[Janizary]

Honda2k7Ex, sounds like you are getting VERY low mileage on your EX. What are your driving conditions, your driving style, auto/manual, etc?

[cojaro]

I started out getting arond 21-25 in the early mileage. 7000+ miles later it's gone up to an average 26mpg nearly all city.

best I've got was 38mpg; 300mile highway trip, cruised at 70 with no AC

[JeShUa]

just got home from my trip.. on the way there.. with 50 city mi got an avg of 33 mpg.. then on the way back tank of 34mpg.. not too happy w/ it but my best so far :]..
3600 mi on the car now @@ haha

[dirtha]

I got 32.6 and 34mpg from my first 2 tanks , 1/2 highway/1/2 secondary roads.
I have an '07 sedan w/MT.
So far I'm very pleased!

[AbsoluteGG]

So far my best is 30 mpg and average between 26 and 27. This is city driving with no ac and windows down 80% of the time. I think its about fair considering the way i drive. Oh yea 2007 LX coupe MT.

[civicowner]

i get 23.5 in all city driving, and 33 mpg in all highway,.

does the mpg go down on the cold weather or on hot weather???

[psyshack]

Us R-18 owners need to get after Hondadata to do a lean burn mod for our ECU. I drive for mpg alot. Have a 43 mpg life time average on my Civic.

We took a 150 mile trip in the civic over the holiday. In the rain, low 40'sf, little wind. Mostly hwy with some small town driving and a trip thru a garden of lights show at a public park. Drove 5 mph under the posted speed limit and only used load driving and got 42 mpg.

[bluishsilver]

i drive around 80% city. i only get around 22 mpg. my car has clocked 1700 miles. how do you think can i improve it?

[Cybergypsy]

average comb after 10K miles 39.2

[JeShUa]

I think I just need to gain more miles to get better mpg as NOW have 3600,, I think once you get around 8k mi the mpg goes up... I still resent getting a 22.3 mpg tank... thats just uncalled for.. even if I were to burnout at every light... a car that should get 30mpg all city should not be getting 25% under its estimated mpg...

It never even sees above 3500 rpm, Its an auto, and ive been using 87 octane since the beginning. Im thinking of installing a wideband to see what kind of A/F ratio this thing s in running at under WOT and normal driving conditions. :Mad:

I'd be interested in seeing the results you get. On another note, since VTEC on the R18 is geared totally toward improving fuel economy, and, it only activates under a finite set of conditions, I'd be interested in figuring out a way to know whem the car is running on the economy cam profiles, even though I'm not having economy issues. I just think it would be interesting to know what percentage of my driving the car is operating in that mode.

I was thinking maybe we could tap into whatever electrical line that goes active when VTEC is active and have it turn on a small LED in the dash or something. The trick is figuring out what circuit to use. Having read a number of these threads about R18's returning poor economy, I've also been wondering if those car's are ever seeing the economy mode in VTEC. If VTEC isn't working for some reason, I'm not sure that would throw a CEL. It would depend on what the nature of the problem is. Just a thought!

I'm not that electronically minded so anyone care to take a stab at that one?

Drive Safe,
