95 SE 5 speed MT. Routinely get between 25-30 mpg and between 400-470 miles per tank. I cracked the 500 miles per tank mark once. Always use 91 octane. CAI, knock sensor replacment and under-drive pulley are only mods on engine so far.

 

stock (for now) 99 auto:
avg about 380-420 miles per tank w/ about 30/70% city/hwy driving

record low:
unusually cold winter w/ led foot = less than 300 mi/tank

record high:
road trip to nor-cal on hwy = over 450 per tank

 

i get 280-310 depending on my driving. shortram with popcharger also hks sport exhaust sittin on 18's

 

Mine is very low because of the System that im hauling in the trunk. It feels like im hauling two dead bodies in the trunk

 

Im embarrassed to say it......250-275 hmm

 

damn ks and fuel filter after replacing those 2 *****es i got wonderful gas mileage

 

My gas mileage is all over the place, mainly because my driving varies. I went about 250 miles doing 80% highway on a half of a tank or 25 mpg a few weeks ago, however I religiously drive on about 1/2 a tank a week and get about 150-170 miles on the 1/2 tank (17ish mpg) driving 90% city. Not only is this 90% city but I shift above 4000 rpms about 20% of the time.

In other words, I could get 400+ in the city and 500+ on the highway, its just I love drving the max to its potential when I can.

 

With lightweight wheels, my gas mileage went up an average of 12-15%.

 

370-450 depends on how much of hurry I am in. CAI, y-pipe, 17x8 wheels, B-pipe.

 

16mpg 95% city which is mostly drive to work 3 miles each way. 95 max, stock with 16's..

 

97 SE, Stock. Bone Stock Heavy Foot.

Hmm. With my old setup:
Blow bottom bolt bearing, transmission with no 4th gear. overdrive was stuck on. and just about every single sensor bad..

just a little over 9MPG city. (don't ask about highway.)

[I would highly recomend this setup for teh skilled driver ONLY)

With new setup:
Bran new engine with 9k miles on it. Bran new transmission with 9k miles on it. overdrive fixed. and every single sensor replaced

28MPG city, (highway, idk yet. havn't done it, been to snowy and crappy out to go try that one.)

 

ouch... 9mpg....

 

97 SE 5 speed, I drive moderately, i put in 89-91 octane and it seems to putting me at about 350 miles per tank with a short ram intake and stock 16" wheels.

 

1st post yeah. Well i have had my 96 i30 for about 7 months now and at first i was getting pretty good gas milage but that disappered for the last 2 months. But i just change my spark plugs oil and air filter and im back to around 350. I was averaging 270 a tank.

 

Abysmal.

10char

 

I just made a trip from Sioux Falls to St Paul....

72 mph most of the way.

295 miles @ 9.1 gallons of Shell 91 octane= 32.4 mpg. I filled up when I left and filled up when I arrived in St Paul. Damn that's my best ever.
