how many miles do you get to the gallon?

[vltnolia]

How many do you get to the gallon for the 2.4L?

[aznpoopy]

26-30 using 91

[Irukandji]

24-28 on 89oct

(i have a lsd so closer gear ratios)

[Irukandji]

jus for reference, dorifto89 gets 24-28 on his sr20

[axiomatik]

On my sohc, I used to get ~21 city, ~18 highway (between Phoenix & LA, but I was going about 85, which was something like 4000 rpm the whole way). However, my car had been running rich.

[sncs14]

24-27 around town always driving it hard. 30 on the hwy

[IAM_SO_sLOw]

how do you guys get that high of a gas milage =( miles like 20 if im lucky... im going to replace all my gasket.. what else do you think i need?
-thanks

[Revolver Ocelot]

Are you running rich, any other problems? My 95 runs a little rich but i can still pull off 28 mpg all the time.

check to see if ur o2 sensor is bad. if it is, replace it and you should notice a difference in fuel economy. dont waste ur money on that TOrnado crap...that shit doesnt work.

my car has always run a little rich

what have you done?

do full tune up service

consider cleaning out the intake manifold with some throttle body cleaner

[KarateBoy]

This is probably stupid but:

Has anyone heard before that bad tires hurt mpg? If so, how?

[Ian]

only a few mpg...but it will effect it


i never get good gas mileage, i'd say <20 mpg just because of the way i drive. HWY isnt too bad though. I drove from Arlington, VA to Petersburg, VA (furthest north virginia to almost North Carolina) and i did it on 1/2 tank of gas or less...so that's about 170 miles

[krustindumm]

28 no matter how i drive

[KarateBoy]

only a few mpg...but it will effect it

Few? So we're talking about 2-3 mpg here in city driving?

Do you happen to know why?

[Ian]

more friction...makes it harder to turn the tires...try pushing a car w/ flat tires...it's hard as shit

multiply that over miles and miles of driving...it'll show in your gas mileage

Ya my car runs a bit rich.... i havent really done anything to my motor... i just change my oil every 3k miles and stuff like that... lol this might be a stupid question but whats included in a full tune up service? =X

[420sx]

i got 30 from highway driving on my nearly stock sr. in town it blows a whooping average of 18mpg. u start raping the Sr, u see that gauge go down

[SochBAT]

20-25 mpg when i lowrev. Putting it in neutral early saves also.

[420sx]

i re-taught myself after puting the sr in to always downshift. i noticed i used to put it alot in neutral to cruise. bad habit and dont really save much gas

[Phlip]

20something, I have not paid much attention to the amount of gas I am putting in my car, because I do not drive very far on a daily basis, generally about 30-40 miles Monday through Friday, only filling up on Fridays and never having less than a quarter tank of gas... I guess I will do some math next time I fill up

[Thrill Capsule]

23-29 mpg, unfortunalty most of my driving is stop and go.

[SHIFT_control]

The best I ever got was ~34 mpg on a trip through the mountians here out to Grand Junction, got 600 miles out of 1 1/2 tanks. It was awesome.

[TachyonS14]

I get about 20-21 in the city and 28-30 on the freeway (and thats going 80mph+).

[omgosh]

27-29 highway in an s13...havent measured city yet.

[Pacman]

I get 20-21 with mixed hwy/city driving. I have a leadfoot so that my hurt it.

ALSO, if anyone has the O2 plug and wire from there hacked S13 DOHC harness I want it please. Mine is soldered on the wire so I cant remove it and its irritating.

[91CRXsiR]

i get 19-22 ... its better than the crx.. i only get 15

[WERDdabuilder]

20-25 on 89

[Whiplash Willy]

My roomate gets around 9 mpg on his DE....something is really wrong.

[KiDyNomiTe]

I never really checked, but calculating how much gas I used on a trip back from Road America, I got about 27 mpg. And for a good 45 minutes I was flying through traffic going 90+ in 4th. The rest was 75+

[allblackS14]

28-30 on any octane, usually 93' but due to gas prices ($2.78) and the fact that I'm still on my KA [SR next month] 87' has become my best friend.

[TachyonS14]

Dayum man, you were basically redlining 4th for 45 min ? :eek3d:

[TEAMMiSCHiEFS14]

the most that I ever got that I tracked was pumping 15 gallons and got 430 miles.. that's both city and fwy driving (80 mph) from Sac to SF to hang out and back.. I was trying to beat my friend's 240 record of 415 miles... haha I think I could of squeezed several more miles but it wasn't risk it..

[Tenchuu]

I get about 20 city/highway on a KA, but I don't have an OBD II sensor in my downpipe as of now, so that might have something to do with it

[Silverbullet]

how the hell do u get these gas milages? most i can do is maybe 350 miles on a tank. The S13 tank is howbig? 15 16gal? 21-24 hwy and city combined.

[ssa_is_shit]

Every tank, I average just over 30. I drive 220 miles+ to work and back, with about 80% interstate and 20% in stop and go traffic. Wouldn't get rid of my 95 just because of the gas mileage and cheap to repair/maintain.

[OdessaS13]

hmm about 21-23/gal, 210-230miles on 10 gallons cuz i fill up wen its 1/4 full.
buts its 1/2 downtown traffic/ 1/2 freeway

[KiDyNomiTe]

Dayum man, you were basically redlining 4th for 45 min ? :eek3d:
redline is 120 in 4th

I wish I didnt have a limiter, there is so much more to go.

[ranisron]

30mpg on highway when the car was totally stock... best mpg I got was 32mpg on the highway.

now with some basic bolt on I am back to 29-30 mpg.

this is a 93 240sx.

My altima has horrible gas mileage --> she is supposed to be the daily driver :(

both Altima (u13) and 240sx have the same gas tank capacity of 15.9 gallon I believe.

I usually use 89. sometimes 93 to clean out the 89 shit.

[CHARLIE2020]

My roomate gets around 9 mpg on his DE....something is really wrong.

Yeah, did you check to see if there's any bullet holes in the gas tank....lol

[driftracer]

I'd say around 26 mpg on 93 octane, but that's on my KA. I havent really checked since my SR has been installed.

[nukeone]

About a gallon per 1/4 mile, but it gets there in under 13 seconds.

[TachyonS14]

redline is 120 in 4th

On my KA 4th gear redlines around 100... maybe you are talking about an SR.

[vltnolia]

keep them coming guys

[infinitexsound]

not enough miles for the dollar spent... im resorting to bummin rides off of people to save gas... ahahha

[tastyratz]

average 20-21mph with my 90 ka24e. i/h/e/test pipe/ ignition/ msd/ magnecore wires/ iridium plugs/ big fat cam, mobil1 oil. 1 gallon per 1/4 run is nuts, i can usually get a half dozen runs out of a gallon but then again I only do it in 15.9. I wish I got better gas mileage... using the shell vpower seems to net me about an extra 1mpg or so. best thing I did for my gas mileage was going auto-manual which netted me another 3+mpg or so.

[sykikchimp]

I get about 21-24 with an AEM EMS.. depending on how I drive.. no different than when I was running the stock ecu. 250-300 miles b/w fillups is about all I'm willing to do.


The car is rated 21city 28hwy I believe when new.

[em0eric]

i re-taught myself after puting the sr in to always downshift. i noticed i used to put it alot in neutral to cruise. bad habit and dont really save much gas

what is bad about going into neutral? i notice i go into neutral alot while driving. is that bad?

[infinitexsound]

no............coastin isnt bad....

[420sx]

its not bad. just bad in my book, for a few reasons:))

[SimpleS14]

I get around 24 mpg

[Var]

20mpg average
29mpg on the highway

[tastyratz]

lol dont tell any cops you cruise in neutral or youll get a ticket :-P stupidest law every. for the rest of you with your much better gas mileage.... go to hell

[DaveSev]

Blarf, I get around 240 miles out of my tank before I have to fill up again...though my needle is messed up, I usually have two-three gallons left when I'm on empty. I've gone well below empty before for like 30 miles, just like Seinfeld...ha...but a few months ago I was getting like 15 mpg, changed my air filter and started keeping my tires filled up and now I'm getting 20. Still not good enough but eh.

[S_14.5]

starting tomorrow, I'm going to get 0 to the gallon...

dayam, gas is hella rising and to fill up is already costs me $40.00+. I feel bad for those in ATL...they got gas prices $6.00+ a gallon...is that ish for real???? anyone here in ATL?

[evrae205b]

what have you done to the motor? i get around 450miles to a tank in my s14 id probly get close to 500 if i wasnt so lead footed. i average 28-32mpg dependign on how much of that is spent on the interstate.

[WONTONnPHO]

I only get 350 miles a tank with 87 gas, even though I goto neutral going downhill. Damn gas is expensive :bash:

[tastyratz]

going to neutral eats more gas than leaving it in gear. when you let off the throttle above (i think its 1800 stock??) the stock ecu goes into a decel fuel trim. i.e. the injectors shut off. you know how your car sounds really different and louder when you let off the gas? thats because its pumping nothing but air.

[Var]

yes but you're engine braking which means you're losing intertia which means you'd have to gain it back by accelerating more later.

[tastyratz]

this is true, different rpm levels have different levels of resistance added to things but it doesnt really make a HUGE slowdown when doing it on my car if done right. chances are you might be letting off the throttle to slow down anyways. letting off the gas and not putting the clutch in should be done while braking anyways (unless trying to brake fast)

[240Driver39]

i reguarly get 30-32 mpg with that mainly being Highway, or highway-ish driving.

[strider hiryu]

I get about 15mpg with my s14 on the hwy. and I have a stock KA. Whats the best octane to use right now im using 91 is it better to use lower octane? and also should i do anything else other than switch the air filter and o2 sensor?

[ranisron]

change your cap, rotor, ignition wire, air filter, fuel filter and clean the throttle body... oh, and a nice oil change.

then you will notice 28+ mpg on the hwy.

in the mean time, search...

[EchoOfSilence]

fuck you guys.
i get 200 miles to the tank if i'm lucky on my sohc.

[Destructo]

15-20 on 91

[!Zar!]

I just got 320 miles off of a full tank and I still haven't filled. I'm waiting for the light to come one~

[420sx]

i got 31 mpg on highway on my sr driving to dallas and back. just dont boost :)

[DaveSev]

what have you done to the motor? i get around 450miles to a tank in my s14 id probly get close to 500 if i wasnt so lead footed. i average 28-32mpg dependign on how much of that is spent on the interstate.

Stock, auto KA, only thing I've done is rip out the intake resonator and disconnected the transmission fluid regulator plug for harder shifts.

I'm getting like 17 mpg. Granted it's all in town, but it's far from stop and go driving...mostly just to school and practice and etc, no heavy traffic.

How would I go about checking my O2 sensor?

[240Driver39]

i reguarly get 30-32 mpg with that mainly being Highway, or highway-ish driving.

Well i fixed a problem i was having, and my mileage actually came down a little...now running around 26-28...so im right on target with factory as that is 97% highway miles

[Monkey Boy]

91 240 about 20-24 with highway and stop and go.

[spikevyxel]

21-23 City (driving hardcore) and around 27ish on highway. 91 Octane

[TibDrifter]

19-23 mph 19 hardcore city and 23 highways 91 octane with s14 sr20. runing mines ecu, i think thats why im getting 23mpg? i wish i got better mpg any clue? my ka i got 28-30 mpg avarage.

[ALTRNTV]

So you bring back a 4 month old thread to tell us that?

[P4rD0nM3]

5-10. City.
25-30. Interstate.

[phreze]

I averege about 20-24 mpg depending if I have boost at 10psi or 8.

[SoSideways]

I've gone about 300 to 310 miles when my fuel gauge's needle is sitting on the last 1/4 tank mark. When I go to put gas in it's usually in the mid to high 11 gallon area (around 11.5 to 11.7) when I do 300 to 310 miles.

That's with some high way driving mixed in with mostly city driving.

On S13 blacktop SR running E5 ECU and fatty O2 sensor.

When I boost I throw a nice cloud of unburnt fuel. Wouldn't surprise me if my fuel pressure was like 50+ psi.

So yeah, I should get higher gas mileage once my fuel pressure is fixed.
