Its a 00 civic ex, and im getting 200 miles to the tank. I filled up yesterday at just above 1/4 tank, at 147 miles, and put in 7.5 gallons, and that averages to be 19 mpg. Why so low? I dont drive in VTAAAAK all day.

 

CEL??

 

do u have intake, exhaust or any mods that would hurt your gas mileage

 

have you done any tune-ups?

Replace your fuel filter.

 

i dont have any of that charcol canister crap hooked up and my car was getting 35-37mpg


new oem spec ngk plugs
fuel filter if its over 60k miles on it
valve adjustment

all things like that..... .also what type of gas are you using? lots of stop and go? lots of hills? wind? etc....

 

I have been noticing this problem with mine too......when i got my car 6 months ago, i put intake, exhaust on it and changed the fuel filter. was getting damn close to 32mpg.....now the last few months i have been noticing that my mpg was getting worse and worse!

 

No CEL's, and all I have done to the car performance wise is added a custom exhuast. I've had the car about 3 months, and its just been getting worse and worse. Also I'm using the 87 octane gas. I dont want to use the more expensive stuff, if its just going to suck it down.

 

you dont need to use the more expensive stuff on your stock motor anyway and like ATEJ8FTW said, tune ups will deifnetly help. Fuel filter, plugs, wires etc...
