how many mpg? how much off a full tank? myne gets around 220 on a full tank. Dont know if thats good or bad.

 

i honestly think that's bad. i was getting about 240 to a tank on my boosted d16. i average about 27mpg boosting on and off.

 

i was getting 315 with my 99 hx before i swapped it

 

ouch, thats rough. my moms 93 Si gets anywhere from 30mpg(360 miles) with me driving to upwards of 45mpg(550 miles) with her driving. she bought it brand new, it has a lil over 150k and runs better than brand new. IF i could ever convince her to get something else ill be buying it off of her.

 

I got a d16y8 w/ apexi WS2, DC sport header, intake, 7.5flywheel and I get around 300-330 per tank.

 

im averaging 27-30 on my D16z6

 

1997 ex, 140,000 on the clock... 31-33 consistent mpg, 80% highway miles usually at about 75-80mph.

 

I put down 440 once on trip to virginia when i had a y8
But consistently i was hovering around 360 miles per tank. Which is around 32-33mpg.

 

48 mpg

 

damn im averaging about 250 or less per tank which is about 26-29 mpg and completely stock.

 

see below.

 

im getting around the same. but thats both on highway and street

EDIT: HOW the HELL are you guys getting so much MPG?

 

im gettin about 34 average on my y7

 

40 mpg on my y7 ej6. shifting right + major patience + maintenence = gas saving ^^

 

35mpg d16z6 with y8 intake @ 8psi

 

i got 42 out of my z6 in my hatch before.I/H/E

 

My d16z6 got 38-45 MPG, 45 being all highway.

Simple ways to improve your gas mileage is keeping your PCV valve clean, your fluids kept up with, your TIRES at max sidewall pressure, and downshifting! Use downshifting to slow down. When you let off the gas with the car in gear, fuel is cut from the injectors so the car slows down without using gas. Slow and steady acceleration is also key. I always shift at 3,000 RPMs and keep things steady. Also be smart about what gear you leave your car in while driving in the city. My rule of thumb is 35mph in 3rd, 45mph in 4th. You want your motor to be able to make power when you give it gas, yet run efficiently. Think of it this way, is it easier to peddle a bike in 5th gear or 3rd gear? Adjust your speed to where the motor runs effortlessly. The more effort it needs to make to accelerate or keep speed, the more gas used!

 

97 hx d16y5 179k still getting 40+ regulary... all I do is keep it tuned up, frequent oil changes using mobil 1 5w30 w/ pure one oil filters, fluids, filters, clean tb, etc... but never seafoamed through the brake booster line.

 

95 del sol with 190k d16z6 got 320, without trying to save gas

 

'95 del sol Si D16z6 140k miles aftermarket rims/tires, exhaust, and intake, I get about 330-360 miles per tank ish, with a gallon or so left... not trying to conserve, If I do highway and baby it I'll easily get like 400+ I've never run it dry so its hard to tell exactly, but I average somewhere around 30-35mpg not trying to conserve in any particular way.

 

97 civic ex with a d16z6 swap built and boosted still getting 30+ mpg

 

my d16 on a full tank would get 320 average to a full tank but idk how its gonna do after my swap

 

my Y8 when I first bought my car was averaging 35.

after beating it to death for the past 30k miles Im averaging around 275 to the tank. which is still great if you ask me, and in no way am i mad about it

 

D16Z6, 44mpg. That was all freeway though, from San Jose to Orange County. Had 398 miles on the trip odometer, and when I filled up I still had a couple of gallons left in the tank.

I usually fill up around 325 or 330, and would have a gallon or 2 still left in the tank.

 

easy 30 mpg, and around 300 or so per tank
