my car wastes alot of gas...ive never replaced my o2 sensor...do u think replacing it will give me better gas? what o2 sensors are good? i want to know prices also and where can i buy them....

 

replacing the o2 will not give you better gas milage. do a tune up or something. oil cahnge, fuel filter, air filter, injector cleaner

 

Are you getting any CELs??

 

naw...

 

if the sensor is going bad, you can get worse mpg

 

I just changed my o2 sensor 2 weeks ago...I had been getting a CEL for 6 months and finally decided to do something aboutit...when I did, I saw an increase of 6mpg

They're expensive though...a new one from Honda runs at least $150..luckily, I scored a used one off a friend for free...and dont go with an aftermarket one, they wont last very long

 

i dont care about the price if its going to improve my gas mileage

 

what kind of mpg are you getting?

if you decide to get one, get a denso from http://www.sparkplugs.com
oem sensors ARE denso, you you cant go wrong...and the price is around 1/3 the cost of what the dealership charges for the SAME exact unit
