thatguybryan · 05-04-2009, 09:52 AM

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.

BoostedCoupe · 05-04-2009, 10:15 AM

^^^^ 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 · 05-04-2009, 12:22 PM

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 · 05-04-2009, 12:33 PM

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 · 05-04-2009, 12:39 PM

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 · 05-04-2009, 01:19 PM

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 · 05-04-2009, 01:25 PM

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

shifts13 · 05-04-2009, 01:35 PM

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 · 05-04-2009, 03:29 PM

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

Bigsyke · 05-04-2009, 07:40 PM

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

guitaraholic · 05-04-2009, 09:26 PM

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 · 05-11-2009, 09:30 PM

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 · 05-11-2009, 09:34 PM

about 24mpg on stock single cam KA.

DirtyS14 · 05-12-2009, 09:44 PM

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 · 05-12-2009, 09:53 PM

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

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

carcrossy · 05-24-2009, 03:51 AM

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 · 05-24-2009, 09:02 AM

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 · 05-24-2009, 09:18 AM

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* · 05-24-2009, 07:14 PM

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.

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.
