What kind of MPG are you getting? - Page 2

Brock · 01-23-2012, 11:51 PM

I was only getting about 23 mpg when I had a 1.8L... probably because it required a lead foot to even keep up with traffic.
Swapped to a 2.5L (with moderate exhaust and fuel mods) and started averaging around 25 mpg (city or highway)
...Then I put on taller tires, and (after accounting for the increased gearing) it gets 26 city 29 highway mpg. You probably don't need me to tell you how poor the factory gearing is for highway driving.
I have exceeded 30 city mpg by driving super conservatively, but that's not the norm.

I get in the upper 20's and can even get in the very low 30's. It's surprising that a 2.5 liter AWD drive sedan with 160+ hp can get better fuel economy than any 1st or 2nd gen Miata that I've had or driven.

Just recently did 30 MPG im my stage 2 WRX with General grabbers. I kept it to 68 mph on the highway and did 340 miles before the gas light came on! Its amazing the increase I got from doing 73 mph down to 68.

27 is my best, with 80 percent highway. EJ22 OBS 5 speed.

WAGONLOVE · 02-20-2012, 08:22 PM

first tank with the new impreza... which was no easy on the gas tank... lots of wot

gotta figure out what she has

a trip down to CO springs to pick up some wheels and tires. and back up doing 85 ish the whole way... which is well over 3k rpms... i got just over 27 mpg!! if im easy on the gas and slow down an bit i can see 30 happening pretty easily! stoked!

Do any if you guys use sea foam? do you see any jump in mpf? Do you ever clean out your fuel injectors.

cystem · 02-20-2012, 08:34 PM

I'm getting21 mpg combined on my 2.5i, 2010

WAGONLOVE · 02-20-2012, 08:46 PM

ive never used it. i am contemplating it though. your 2.5 a 5 speed? what are your driving habits like? weight of the car?

I Like It Sideways · 02-21-2012, 11:16 AM

I have averaged 24.7 mpg in my '06 WRX since I bought it last April. Mixed city/highway driving. Best I ever got was 34.17, worst was 16.58

I got ~15mpg in my '91 Legacy SS on it's most recent tank...

A1337STI · 02-21-2012, 11:19 AM

I have gotten 30 mpg when my car was fwd + 1.8

for the longest time i was getting 20 mph (tops) after my RS 2.5 swap but i had a bad knock sensor + rear O2 for a while. finally fixed the knock sensor and i just got 26 mpg driving down to Ridgecrest. think it dipped down to 22 ish on the tank that i rally crossed on, and did the first half of the drive (lots of up hill) keeping 75 on steep uphills wasn't good on the tank.

i need to fill her back up, but i think the last tank i got around 30 . did 230 miles so far on what looks to be about 7-8 gallons of gas.

oh what size gas tank should an RS 2.5 have? mine seems to be a 12 gallon tank (from a 95 awd)

cystem · 02-21-2012, 01:16 PM

Im rocking a fairly stock 2k10 2.5i EAT. about a 2" lift with springs and 215-65-16 tires. i weigh about 3200L,B man seeking woman =-)

While my combined average is ~ 21-21 MPG over the course of a tank i drive hard and ~80mph on the highway.

using my on-board MPG computer (i know its not supper accurate with the 65 tires) i was getting 25MPG at 75-80MPH and when i dropped down to 65-70MOH i was getting about 30-32MPG

02wrxRally · 02-21-2012, 01:56 PM

I used to get low 30's on the highway stock, and could get down to 14 or so womping on it. Since going stage 2 I've always averaged around 24 no matter how hard or nice I drive. (always just used #mi driven / gallons to fill up, so these are tank averages)

Lately it's been consistently on the low side of that and dropping (like it's block), but I just found a sticking slider bolt on the brakes along with a diagonally worn brake pad

- now lubed up and ungunked, so I'm hoping to shoot back to the 24+ range

Jake, you're back in a subie? The sexy white wagon's gone, right? thought I saw an audi now?

WAGONLOVE · 02-21-2012, 11:03 PM

yeah white bugeye wag is gone sadly.... i bought a 4 runner, but couldnt deal with not having a subie... so i bought a 98 impreza L wagon

i love it so far!! also got an audi

for the wife!! that is what im driving to 100 aw!! you gonna go this year??

02wrxRally · 02-22-2012, 04:56 AM

yep, crewing for Conte, stop by and say hi!

peacedaddy101 · 02-22-2012, 09:18 AM

I use the Lucas oil injector cleaner in every tank and can tell by the mpg when I don't use it. I usually get between 20-23 but that was with some mixed up vacuum lines. Hoping since I fixed that problem and don't have anymore cel's it will go up.
