Hey guys my b16 has some suck *** gas milage. I have changed the plugs and air filter but it still only gets like 21-23mpg. I want any and all the reasons this could be goin on, thanks for your help

 

New o2 sensor(s)
Fuel filter
Oil change/filter
Make sure tires arent underinflated
Fuel injection cleaner
That tornado thing really helps to ..
And check for vacuum leaks ,,because a leak will get you shitty mpg..

 

Pick your foot up off the throttle.

 

haha, stop running it into vtec at every traffic light, no matter how fun it is.

Exactly! I thought you said "horrible" gas mileage?

 

I know how you feal, my B16's gas milage was always up and down. It was not because of a lead foot. Now that I have a crv-tec in there the gas milage is always bad. The next thing for me to buy, to solve this gas thing it a fuel control. I will let you know if things get any better.

 

does that tornado thing really work?

Damn right..

Put it in my fathers car and he got about 7-10 more mpg..I doubt if he got any power but it does help with gas milelage..

it works till it falls apart on you,
that **** is put together so shitty that it breaks really easily. id check your fuel return lines and your fuel feed lines going into the fuel rail, you might have a leak, i was leaking gas after my turbo setup, i was getting about 8mpg

 

I notice the same with my b16 but you know what it is? gearing. you jump on the freeway for a good mount of time there goes ur gas. 4k rpms at 70? yea. so about 23mpg sounds pretty close.

 

exactly, 5th gear 70mph is lol 4800 rpms on my stupid car

i still get about 26-30 mpg though

 

damn 4800? u go like 13's with 40 series tires or something? I have the stock crx si wheels and tires and i sti right on 4k at 70mph and at 4800rpm i dont know how the hell ur getting 30mpg? Thats crazy! in my ls crx i got 31.9 average everywhere driving.

 

b16 with a j1 tranny, its uses the same gearing in the 96-97 itr trannys

 

yeah has anyone swapped out 5th gear in a b-series tranny for a longer LS gear?
that would be the ish

 

i can get 35 mpg in my crx gsr with uberdata. I'm running 15.1-15.5 a/f partial throttle and if i never hit vtec it does pretty good. But even if i do i still get 27 mpg. Time for some partial throttle tuning. I dont even run a o2 sensor no more i just started tuning it myself as weather changed. I run a little lean but i have no detonation problems or anything the car runs like a champ. K Maybe its time to bust out some turbo edit or uberdata and show that ecu who is boss...just a suggestion. I know its not for everyone buts its worth a try.

I have a ys1 with even shorter gears than a j1 and I'm running 13's with 40 series tires and at 70mph i'm at like 4100-4200 rpm. edit: nvm if you stay in 5th gear a j1 is higher. btw I get 30+ mpg on the freeway and 24 or so when I rip on it.

 

hey i'm not a leadfoot my car goes up to 3500rpm at the max, so the leadfoot thing isnt my problem, however i do think my vacum lines are screwed up, i will post a pic to show u guys what i mean, maybe one of you will know which lines are screwed

 

when im in boost lol the gas gauge moves as fast as the speedometer, then when i let off it goes back to normal
its pretty entertaining.

 

damn, you're complaining about 23. i've been getting 10 or less in my 97 gsr swapped hatch. ****

 

remember its 1.6 don't mean it will save gas.


I had some badd gas mileage with my b16b maybe cause of my supra fuel pump. but anyways I have a si now now this baby saves some major gas.

fill up was 10gal like nearly 20bucks.
regular 88.

 

Would like the see the pic man. You would know if your vacuum lines were not right.

 

Here are some pics of my vacum lines
