Gas Mileage

[Tom25666]

what kind of mileage are you getting? give a quick rundown of your setup, octane used, etc.

s13 redtop, basically stock, smic, ele fan, no a/c, K&N filter= 25mpg city on 93 octane

[guitaraholic]

I get around 23-24mpg mostly city driving. But that's getting to the speed-limit assertively lol. I have the MBC set to around 12 psi or so.

98 Kouki/ 98 Kouki SR/ FMIC/Z32 MAF/525cc injectors/Walbro 255lph/Chipped ECU/3" Full Exhuast

[Jsellers]

25mpg

Bone Stock hahahaha

[SidewayZ-s14]

I wish i knew, but i do know that it's poopy.

[DataXUnknown]

man im getting only about 17mpg city. can anyone help me out with this? im running a fairly stock sr20 blacktop on 91 octane, hks intake, 3 inch exhaust piping all the way,z32 fuel filter, walbro 255lph fuel pump. no emissions equipment or fpr. could it be i need a fpr? im pretty sure im running decently rich.

[Banegraphix]

20-23mpg on 93 octane gutted s13 with redtop and top mount T3 with basically every bolt on Isis makes and ROM tune no emissions at all with 3 inch exhaust. AFRs are around 14 to 14.3 DD and low 13s when im actually on it.

Heck. I have pretty much the same setup.
I fill up my gas tank full and it only gets 200 miles on it before it's at empty.
I'm not sure how many gallons are in the s14 tank 17?

Can anyone figure my millage out? Is it like 11mpg? lol!

[blitzsti22]

get about 24mpg with stock ka24de fill 91 octane

[blitzsti22]

every time i fill my s14 from empty i always put about 12 gallons, i thought i had a bigger tank

[GSXRJJordan]

Hahaha you guys.

First of all, this has been discussed MANY times.

Secondly, Wes, you need a FPR - you've got a high flow pump, and are probably running too much fuel.

Thirdly - the S14 takes over 17gals of fuel - ask how I know :/

I run a redtop, GT28R, stock ECU/injectors/maf - my S14 is stripped though, very light, and has full aero (and is pretty low).

I get over 30mpg on the freeway, about 20mpg if I'm on it a lot around town.

[undesiredshoe]

17 mpg city....ka24e on e85

[guitaraholic]

I still have the stock FPR for now, and my mileage is just fine, and just changed the spark plugs after 35k miles, and they were perfect. Not running too lean or too rich.

[clark]

all you guys with sr20s and your 26mpgs and no fpr. are you sure you're calculating with a 15.9 gallon tank? the fuel needle is deceiving

S13 - 15.9
S14 - 17.2

i get about 22mpg city/highway mix

ugh that's horrible

sr20, z32 fuel filter, walbro 255, stock fpr, stock smic, no boost controller, but she purrs like a kitten

[LayNLow]

24-26mpg city and 30 highway on my 92 s13 with a 220K mile 95 s14 KA with intake and exhaust, stock bodied with coilovers and a welded diff. 93 octane with up to 10% ethanol. Hate that bullshit, but nowhere around here has regular gas.

get a tune?

[fliprayzin240sx]

^^^Get a new 02 sensor before anything else...

[NMs14.5kouki]

im getting 25 to 26 in my s14. blacktop s13 sr, gt2871 .86 ar, with a v mount, 850 injectors, z32 maf, tuned.

[ilikebooze]

I get dick for milage until i get a proper ecu. Im running a s14 sr20, 272 race cams, BC valve springs and retainers, hks exhaust, blah blah. All i know is that it runs pretty rich. Hell, my rear bumper is gettin pretty dirty from it. Thats what i get for running agressive cams on a stock ecu

[240s4life]

^what kind of injectors do you have?

[singlecamslam]

I get 70MPG.....










On my scooter. And around 25 on a s13 redtop with s15 turbo. Hey GSX Jorden, if you have an after market Fuel Pump and an after market FPR, do you set it at 43 PSI with no vacuum right?

[I LUV MY S13]

20-24 stock sohc...highway mpg is shiitty ha

[I LUV MY S13]

ya lol i know that as soon as my needle hits empty i know i still have at least 100 miles until its really empty. i have n/a ka24de with short ram intake and apexi n1 style muffler only running 24 mpg. oh and im also running walbro 225lph fuel pump with no problems what so ever as far as running rich or lean

[hOngsterr]

what common things
can cause poor gas mileage.

[MandTPhotography]

^ With this guy.


I get like 18 in the city and 28 on the highway....wtf.



S13 blacktop, walbro 255, T25 @ 15lbs, FMIC, 3" turboback, etc;.. It's tuned as well.

[thesimpleS13]

i can't really give a definite number, because I'm really not sure. But just this past week I got 304 miles to a tank, and that was including a drift event.... SR btw.. lol mostly stock with 3" exhaust, test pipe, and downpipe...

[95KA-Turbo]

I get 24-26mpg in my 97 240 with S14 SR, HKS intake, tube mani, 3" elbow/dp/cat/NA Trust DD, FMIC, on 10-12psi using 93. I get way better gas milage on long trips, like 30mpg.

My new DD (96 Accord) gets 30-32mpg without even trying, haha, and it takes 85.

[aoiken3]

i get like 10 or 20 more past the 300 mile mark. so that's roughly 25 mpg everytime. i wish it could get better but its better than a lot of other cars out there tho

[MrChow]

Stock KA 184k miles. 3" exhaust, intake and jwt ecu
City 23-25
Hwy 30-32

[aNskY]

right now, like 10 mpg.. lol..

nismo 740's
walbro 255

pfc

gotta get her tuned

[KoukiMonsta]

i get like 22-25

yea im rockin like 15 mpg...

[thatguybryan]

Do you guys still drive your cars after the needle is at the E line? I'm asking because when I fill up, I usually only fill up 12.8-13.2 gallons. Using this method I'm getting like 18-20 mpg, but obviously if I go past the E I'll get better MPG.

edit: 98 s14, stock ka24de

[BoostedCoupe]

^^^^ i do the same. the way i figure up mine is...fill the car up full, drive it untill your on 3/4's of a tank. multiple the millage you got by 4 then divide it by 15.9 if s13 and 17 if its an s14. I usually get 20mpg in my s13 vert with 18" failmaxx's welded and 3" catback. My s14 is around 20-22mpg 3" catback and coils. This is all city btw. And shifting at 3-4k.

[98koukile]

I do what any person who doesn't trust the fuel gauge would do. Fill up, set to 0 and drive, fill up again, divide miles by gallons to fill. It would be even more accurate to use a gps to measure miles driven but my method is close enough. I get just shy of 27 mpg combined driving with 89

[Bigsyke]

I was at about 17mpg, swapped my auto for a 5speed with a fidanza flywheel and 1pc driveshaft. 29mpg at least.

Almost like my gas needle on the cluster is broken, I hit 350 miles on a tank, I would barely get 210 before. Dont know what happened but I love it.

[Jdm.I.Am]

91 kade

AEM intake
RS*R 3" catback
A/C
P/S
M/T

89 gas

about 25mpg on a weekly

i get around 300 miles to a full tank.

[GaMBiTx]

KA24E ALL STOCK, 15 MPG AVERAGE ON 93

Just recently put 1/3 can of seafoam in gas tank to clean injectors and 1/3 through intake...maybe it'll run better now?

[rsibley22]

like twenty haha got it from mapquesting everywhere i went for a tank cuz odometer no works lol

[shifts13]

22mpg city for me with heavy boosting here and there. blacktop with bolt ons 12psi. Just replaced my o2 sensor a few days ago so we'll see if i get any improvement.

[xs240]

How do you guys realize how much you adjust your fpr down when running a KA with a wallbro 255lph?

[Bigsyke]

^^^walbro shouldnt adjust pressure, only volume, unless you got the high pressure model. Mine didnt change when I went to the walbro

[guitaraholic]

I believe the High Pressure model is the only one available, and I believe (don't quote me on it), that its the stock pressure used on the 240sx.

[bshotts]

Just filled up at Shell -------> 27.5 mpg/390 miles to the tank. S14 with S13 SR, T28, 555 cc injectors, supporting mods, and most importantly out-of-the-box Enthalpy-tuned daughterboard. Can't imagine if I could get it steady-state tuned on an actual dyno...30 mpg maybe??

[jigs]

about 24mpg on stock single cam KA.

[DirtyS14]

Redtop SR w/ intake, exhaust, fmic, stock ecu/boost/injectors etc. and stripped interior.

I get about 22-23mpg city... and city is 5300ft above sea level :(

[palmdale_mob]

Fresh oil change and pushing 25 mpg city+freeway combined on a stock KADE

[darkcashpimp]

man im getting only about 17mpg city. can anyone help me out with this? im running a fairly stock sr20 blacktop on 91 octane, hks intake, 3 inch exhaust piping all the way,z32 fuel filter, walbro 255lph fuel pump. no emissions equipment or fpr. could it be i need a fpr? im pretty sure im running decently rich.

Shift sooner by that i mean around 3000 rpms, dont floor it unless you need to haha wich is hard to do.........

[carcrossy]

92 ka24de

The best I can do is 20 miles per gallon. I fill up and keep track of mileage and than fill up again so I know exactly how much fuel I used. I fill up until it spills.

I guess I better switch to at least 91 as ive been using 87. fsm says at least 91. not sure if 93 is the better choice for the dohc.

[jr_ss]

I use to drive like a bat outta hell around town all the time and I saw about 20mpg... On the highway I saw 28mpg at 80mph...

The S14SR's trans has a higher 5th gear than that of the S13SR's... Think its like .838 for the S14 to .752 for the S13...

[Silverbullet]

S13 hatch with SR, 225 and 245 sport tires gets about 27 on the high way. It runs on 93 or 94, whatever premium is.

S14 with KA on 195 and 205 pos tires gets over 30 on the high way. I run my S14 on 87 octane.

[fliprayzin240sx]

I'm jumping for joy if my car right now breaks 300kms on a tank. 850cc injector tuned for power only ftl... then again, it was worst before I turned on the stock o2 sensor feedback on the PFC. I was getting 220km on a full tank.

sounds familiar.... i personally LOVE getting 240 miles a tank.....yes 240 no joke

edit: 98 s14, stock ka24de



WAT?

LOL

getting more miles per tank does not equal more miles per gallon.

fill up all the way. set trip to zero. drive a bit. you dont have to empty the tank... fill up again, record how many gallons went in, and divide by how many miles you drove.
