I have an h23 in my GSR and i was curious as to what type of gas mileage you guys get in you're h23 powered cars??
i looked and got tired of searching for h23 users
thanks

 

30mpg. But I always just put in neutral when I see a redlight ahead, shift at ~2700 rpm. I do go fast on the freeway though so I'm sure I could get better MPG. Gas is just too high here it's approaching 2.80 for the cheap stuff

 

23-26 city

 

I sort of have a H23.

97mm stroke
87mmm Bore
JDM F22B DOHC nonVTEC cylinder head.
Crower stage 3 cams

I get about 25-28 in the city and about 33-34 on the freeway with an M2F4 short geared transmission.

i get around 300 a tank. with pretty safe driving

 

H23vtec auto ( ). I get 30-32 mpg highway, about 24ish city.

 

well i actually just checked what i was getting the other day it was slightly over 20 mpg in the city. SUCKS!!!! anybody knwo what i can do to fix this

 

I'm embarrassed to say I struggle for 26mpg on the freeway. But my valves sound like they need a serious adjustment, so I'm hoping that will restore it.

Is that better than when you had the H23 tranny?

I hope you're not using the cheap stuff!

When I bought the car it was around 26-30 depending on conditions.

Now after some basic mods I'm at 22-26. :\

I drive during peak hours so i think I could get better. City driving takes a lot of gas too.</TD></TR></TABLE>

holy hell, do you guys have a big *** tank or what?
on a 11.9 gallon tank, i barely get 320 on good days and 270 on hard city/highway driving.
but since i go on city driving all the time, it's about 250 lately.

And this is just IN MY SOHC Civic!

 

With my 92, I used to get between 375-400 per tank. Mixed driving.

 

I've gotten 450 on a tank before, going to vegas without stopping and I must've been bone dry. At 30mpg and 15.9 I didn't have much left. Anyways when my gas light goes on and I go to the station it only fills up to 13.5 gallons so there's a little more than 2 gallons left in the car when the light goes on (at least for me).

 

Interesting - im getting around 20-24 and around 26 on highway - but ive heard that a SRI and Headers will cause you to have poor gas mileage.

really? i thought it would help it? because they makes it brethe better?

 

Does anyone know for sure ?? thats just what ive heard.. never know..

 

my last tank I got 25.5 mpg, mixed city/highway, but to be fair everyday I have to floor it to work from school to get there, so I'm doing 80-90 for about 5 minutes every day, don't know how bad that short trip affects it

 

*smiles*

33ish on my f22a.

 

ive gotten 220miles on 12 gallons my car is gay

 

ya i only get 200 mpg on my 98 prelude...on my 96 that thing went in the 300's, i have to say im dissapointed.

 

wow! 200mpg! thats amazing!

i onlyget about 26mpg on the h23 in...i guess you can call it city driving
we have no highways on guam
haha

 

I can get up to 400 miles to a tank, but that's with mainly highway driving.

 

wow sounds like some of you drive SUVs or have really heavy feet

 

Does an SRI and Headers cause worse gas mileage??
anyone know? and dont just state how much you got out of a tank it doesnt help anyone...

 

25 mpg


boosted too


but driving like a grandma

 

It's so weird, i have a 1.8 base nissan sentra, it says I get good gas mileage, but I swear, 10 gallons is gone in like 5 days, of 3 trips to school (15-18 miles each way) and trips to work. I swear im only getting like 180-200 to a tank, but its because its stop and go city traffic light driving, and some freeway driving. It just doesnt add up, and makes me mad.

Oh btw, longer gears don't have to do with mpg. rpm's doesnt have to do with mpg, throttle position does. common misconception.
