i own a sohc, d16y7. i used to get like 50mpg....until my friend took my car. i drove it for the first time in a couple of days, and i drove no more than 50 miles today and almost half a tank went by.....does anybody have any ideas of what it could be????

So you filled it up to full and then drove 50 miles and it went to almost half way right?
You probably have a stuck open injector. I would assume that the car is blowing black smoke also.

idk, can you give us more information? What car is it? And you def didnt get 50 mpg. Even driving like a little old lady you still cant get 50mpg.


Its possible its an open injector, but i've never heard of that happening.

this morning i had more than half a tank..... and i probably drove for like 50-60 miles today, cuz i was waiting for a new starter for like half of the day.....and now its almost on E.

Does it blow black smoke? IF your car is running really rich, it'll blow black smoke. Try filling it up to full then keep track of your mileage. Civic gas gauge as swings on me, one minute its at the half way mark then at the 1/4 then back up to half way.

ostapsi

no black smoke, nothing, car runs like always but it feels like some one is stealing my gas everytime i turn the car on and drive. like its really weird, and my car is all stock. it was normal before.....its like if i had a GSR ecu or something....idk

boostedcivicsir

if your o2 is getting lazy it may do that but over night from letting a friend drive it? huh.

ostapsi

could it be that i need an oil change....my oil was low so i added a quart of 10w 40.....and im like 400 miles over my oil change.....thats the only thing i can think of right now.

MilanoRedEk99

How many miles on the motor?? 10w-40 oil I think is a little thick and it may be affecting your
mpg just my .02

drave

10w40 is very thick. get an oil change asap.

D16SiHatch

10w-30 is preferable, but 10w-40 will work fine. 30 thinner and better for colder temps. 40 is somewhat thicker and better in hotter temps.

BlitzSix

Why would you put 10w40 in?

400 miles? Why do people find it so hard to do regular oil changes...that's probably why your car burns oil in the first place.

D16SiHatch

he lives in miami florida not canada.. i think he'll be fine

400 miles over an oil change isn't going to cause any major problems. its not like at exactly 3,000 miles the oil will just degrade instantaneously and cause catastrophic engine failure. thats ridiculous.

slo_hatch

acutually d16sihatch...he did say he was 400 miles over his oil change. not to be a smartass...just sayin. lol and i would change the oil and check your injectors and o2 sensor. it really has stumped me tho...i would think you would have black smoke shootin out. my hatch does. lol

that would be fawk'd up hahaha

gizzerhatch

check if you are leaking fuel. maybe you have a leaking line or on your tank.

Jimster480

well our friend (ex friend now) did "steal" it, but he didn't really **** that up, at least not as much as we know atm. He just ripped the system out and sold it for crack, got his brand new tires slashed, grinded his gears, and broke his new starter, and cracked his dashboard.

Jimster480

bump.
