S14 mpg challenge....?

[JGON85]

What's up guys, trying to improve gas mileage so hopefully people get into this.....

What's the most miles that you gotten out of a full tank? What brand/grade gasoline did you use? and what mods install if any? What kinda driving? etc.....

Give averages and all-time bests

I've gotten 317 mi all time
average 280-295
chevron or shell premium
car running stock
driving mild on the streets 80 on freeways.

[onepuff]

I'm getting between 300-350 depending on how i drive.
RB20DET
Probably a little more in reality since i have a J30 VLSD and taller than stock wheels and tires. Speedometer reads a few mph low.

What do you have a KA?

[spikNspan]

I dunno what I get, my speedo don't work.

[Zero-Offset]

Lately i've been getting around 200-220 and thats with my SOHC.
gotta have a little less of a lead foot me thinks. :O

[Canaduh]

i usually get around 350 average. regular 87 octane. I use sea foam once every couple months, and injector cleaner once a year. (dunno if that makes a difference.

[Marcus]

Na KA
aem short ram, hks catback. sun auto voltage regulator(THIS SHIT HELPS).
mild freeway/streets. i got 380 average. sometimes 400 on 91.

one time, i got 430 coasting down hills shifting at like 2k, drafting behind trucks. no radio, no ac. windows up. haha. during summer.

kat
greddy 20g, 370s, walbro255, jwt ecu, hks catback.
on 91 i get 290-310

[Rnz520]

On an NA KA with a aem intake, ebay S14 shorty headers, test pipe, and HKS catback (very quiet) I have gotten around 445 TOPS baby driving 90% of it freeway.
Usually I will get 350 to 380, and I do get on it from time to time, and equal mix of freeway and city driving.
Also I run mostly 93, with a splash of 89 whenever I am feeling cheap.
Motor was rebuilt not long ago tho, has maybe 2600 miles on it.

[kdashy]

KA, Intake, 2.5" catback.

midgrade to premium gas, depending on how cheap I feel.

387 miles on last tank, and I didn't fill it to the top.

about 32mpg average.

For posperitys sake:

[LA_phantom_240]

I get about 28mpg interstate, windows down, 70-85mph with no sudden hardcore acceleration.

22mpg or so city, shifting kinda high at 3-4k, light throttle.

[Forge_55b]

i get almost 400 miles on a full tank just driving slow, shifting at 3k or lower sometimes, and actually driving 65 on the freeways......

occasionally i do drive retarded and do 100 on the freeway or redline it on the streets but saving money on gas and staying away from tickets is nice too

[don_bagz]

kade, about 380-400 a tank at 87..

does premium or other brand help in milage?

drive around 70-75 on freeway.. i would say 60% freeway driving

[UNISA JECS]

GAS: Arco 87 Octane

I've gotten 381 miles, then went to fill up and got in approx. 14.7 gallons in the tank, all this driving was on a stock KA24DE bone stock engine wise.....at an average speed of 90mph with burst over 125mph....long long long road trip, car was automatic also atthe time.

[sunnys14]

Built KA-T, GT3076R, 850cc, enthalpy ecu.

City 17mpg
HWY 21mpg
NO BOOST

I don't even drive fast and 90% of the time stay out of boost. I usually coast about 8-10% throttle everywhere. No idea why i burn so much gas...

[s13silady]

around 380-390 for me... gorgeously running KAde.. intake exhaust headers with no emission equipment.. 400 if im not getting dome shots.

[EDz s14]

last time I filled up was 300 for 13 gallons

[az_240]

About 380 miles each tank

[Koosh.S14]

Once three years ago on my way down to FL on spring break I got something like 472 miles on one of my fills. I was using 89 Chevron in my essentially stock KA. I was pretty happy. But I generally get 400 +/- 20.

[lightsource]

SR20, 3" exhaust, walboro 255lph, 300zx fuel filter
~330 Miles per tank - 91 Mobil
~410 Miles per tank - 91 Shell
~390 Miles per tank - 91 Chevron
~350 Miles per tank - 91 76

[bunnathp]

about 200 a tank? iono whyy =(
on a stock KA.

[Yellow4g63]

I get about 280-300 and usally put in 12-13 gals to fill it back up in my Auto S14. My low gas light don't work I think.

[sncs14]

MPG= Miles Per Gallon= miles driven/gallons of fuel used, not how far you've driven on a tank of gas. I only say this because the fuel gauge isn't always accurate, and the only way you really know what kind of mileage your getting is to do the math.

Up until last fall I was going about 370ish miles before feeling the urge to fill up, about 25-27 mpg was my average for mostly city driving.

Now I get 23-25 mpg and occasionally better.

[dread]

SR20DET
Always run on shell 99octane
get about 300-350 depending on which roads I drive.

More on motorways (freeways)

[aNskY]

i averaged 29mpg DD'ing a stock s13 sr in a s14 (93 oct) thought that was pretty good.

[95KA-Turbo]

Stock S14 SR with side mount and OEM silvia fuel pump. I drove nothing but interstate for the first 180 miles and it didn't even use a quarter of a tank of gas. So interstate only driving I'll get around 31mpg and my average MPG which is a mix of city and interstate I get around 27-28mpg....or like 380-390 miles per tank - I don't let the light come on or anything so I am sure it would be around 420 if I let the light come on.

If I rip on it some it will get ~24-26mpg.

I usually shift between 2800 and 3000 rpms, I drive 5-10 over the speed limit around here (interstates are 55mph here), I just watch my boost gauge and make sure it doesn't go up that high, haha.

Oh I also only use Shell 93 V-Power gas.

Its been proven in Mythbusters that this doesn't work unless you ride dangerously close behind a truck. Either way, It makes little difference.

[nismo 240sx]

what?..lol..first time i did an oil change i got a little more than 300miles on 91 and lately i been getting 200...and i just did an oil like a month and half ago maybe less...and i shift sometimes 3 or 2 1/2....

[FRpilot]

been consistently getting 360-370 a tank (~13 gallons) on stock ka24de on my dd s13 which equates to about 28-29mpg. i do probably 90-95% freeway driving.

[2ilvia]

completely stock s14 (well k&n air filter and muffler tip) #3 had slightly low compression and i got almost 400 doing 72ish on the highway (cruise control), gas was sunoco 93 octane


i just rebuilt it with sohc pistons and it will be interesting to see what happens

[soldiaboy]

Im getting around 25mpg, how can I improve my mpg?

[ki_JDM_ds]

1993 Nissan 240SX SE - Completly Stock - Mobil 1 Clean 5000 - Wix Oil Filter - QuikTrip 89 Octane

I have been tracking my milage and gas money since 7-15-08 (163486 miles) As of 10-15-08 (169241 miles) I average 27.75 city and highway.

On 10-5-08: 168828 miles 12.123 gallons (Full Tank)

My last fill up 10-15-08 I put in 15.178 gallons (Full Tank) 27.20 MPG and I got 412 Miles to a tank. lol it stated to sputter as I pulled into the gas station.

The best I have in MPG is 29.40

fuck mythbusters.

jk. it was a joke.

Avg MPG is 25 with 50/50 highway and city.

[Mangudai]

I get about 280-300 and usally put in 12-13 gals to fill it back up in my Auto S14. My low gas light don't work I think.


Mine neither. But damn, is there anyone here who does mostly city?

[ellisonrox]

used to get 400/tank

now my odometer doesn't work so well so i can't tell anymore :(

[bunnathp]

well iono how big my tank is. but i fill like only max 10 gallons and i get 19?
so maybe 19 mpg? i think i get 25 highway

[don_bagz]

well iono how big my tank is. but i fill like only max 10 gallons and i get 19?

next time you fill up, get a full tank and reset your trip meter.. then the next time you fill up maybe a week or two later, just see how much gas you put in to fill it up again.. then, divide your gallons added to get a full tank, from your trip meter... there yah go.. MPG...

[240cracker]

miles per tank: 180-200 to a tank if im lucky

to me it seems like i get worse on the freeway cuz its always in boost

[skate_osiris_4life]

im gettin about 16mpg. haha but ive been drivin like a dumbass lately. ill have to see whet i get on half a tank drivin right. lol

[nissanguy13]

For some reason I'm getting horrible gas mileage. I go about 4-5 miles a day round trip from home to work and I was almost empty at 150 miles when I filled up recently. I have a 91 auto with an s14 KA with intake and catback exhaust. I'm starting to wonder if my gas gauge is off since my car is running fine. I run 87 octane from usually shell or flyers.

[aoiken3]

kade w/ egay intake only n routine oil changes n my baby got 350ish on a tank. im always chill when driving but i have bursts of a heavy foot. so about 27ish mpg. half n half city n freeway

[steve shadows]

Not and S14, but my test car makes close to 500 hp at the fly and gets average 30 mpg (850cc SARD Injectors with return line and Denso Fuel Pump).

thats right, 30mpg hwy...

With steady state tuning you can maximize each individual cell on the maps perfectly all through the EMS (any ems). Very very responsive and better spool lower end torque are achieved with this method without needing twin scroll and fuel economy is massivley improved over other methods of tuning.

granted it gets about four mpg if I am at FOT :keke:

[turtl631]

I would get 28-32mpg on the highway with my old ka-t. This was with some luggage in the car as well as my gf, just driving anywhere between 60 and 85, and pretty much just cruising. When I got 32 mpg I kept it under 75 and wasn't really getting on it at all.

[Marcus]

MPG= Miles Per Gallon= miles driven/gallons of fuel used, not how far you've driven on a tank of gas.

What's up guys, trying to improve gas mileage so hopefully people get into this.....

What's the most miles that you gotten out of a full tank? What brand/grade gasoline did you use? and what mods install if any? What kinda driving? etc.....



that sort of thing's not my bag baby

[xkamikazestormx]

i get about 450 ona full tank

[kenshinS14sks]

SR20, 3" exhaust, walboro 255lph, 300zx fuel filter
~330 Miles per tank - 91 Mobil
~410 Miles per tank - 91 Shell
~390 Miles per tank - 91 Chevron
~350 Miles per tank - 91 76

ok . . . what? ? not about the results but 390 - 410 . . . i have the sr20, 3" exhaust, the 300zx fuel filter . . . MINUS the walboro and im averaging 300 on 91 chevron. what's your magic?

[95KA-Turbo]

Probably staying out of boost, LOL. Seriously DON'T go into boost and you'll get amazing fuel economy.

[murda-c]

Remember that tire diameter will affect your odometer.

I average 27 with an even mix of cty and hwy

[renegade_ewok]

Zenki w/S14 SR w/bigger injectors (550s), windows up w/air blowing (not AC) and radio got me like 300 to a tank when cruising, but this also is getting up to 80+ a few times and cruising the majority of the time 65+

[murda-c]

I cruise at 75-80 every day, should probably stop.

on a trip to PA i averaged like 34 mpg because of the cops that were everywhere, haha.

[chituntang]

I used to have a stock KA in the S14, it got 380 to 400 a tank (28ish).
Now it has a SR in it. With fmic, 255 fuel pump, 3in elbow and downpipe, I have 20-23mpg...

[sillyvia13]

na ka s13
32 mpg KILLIN shit, ac on drifting here and there... driving like I should be!
I have alum crank pulley, alum flywheel, alum d shaft, ROM TUNE! with around 200rwhp and tons of extra's! in rom tune

I have never done a highway run, but sure it gets better than 32!

put one in your car, ive been seriously watching alot of youtube videos to come to the conclusion that it does work, according to people who have done it *and then theres the people who say it doesnt work.* Dont buy any plans, just watch enough youtube videos to figure it out. *every asshat is trying to make a buck on the info*.

YouTube - 41mpg Nissan 240sx sr20det hydrogen hho hydroxy fuel saver Greenville SC installation (http://www.youtube.com/watch?v=1_8C4ft0IXI)

Im curious i want to try it myself... just not sure where it should be plumbed into the intake, sending it thru the maf might be good because it will get measured as air, but not sure you want this stuff running thru the hot turbo since its combustible.

[EDacIouSX]

Its been proven in Mythbusters that this doesn't work unless you ride dangerously close behind a truck. Either way, It makes little difference.

if you are driving like 40 mph behind a truck im sure it aint gonna do shit. but if you're going 80 mph behind a truck im pretty sure it would. depending on distance of course.
