Default 05 Cruiser eating gas

Hi I have a 05 Cruiser with the basic 2.4 in it with 130xxx miles on it. I have noticed the past month that I am using alot of gas. I just put new spark plugs and wires on it last summer so its in tune as far as I know. It is also not leaking any. I also replaced one of the o2 sensors about a year ago. Any ideas??

Replace the other 02 sensor if it's never been done before. Also replace the PCV valve and throw in a bottle of Chevron Techron into the gas tank

Your first post is very incomplete as far as information to help you goes? We all get bad gas mileage? What was your average mpg what month were they established. Where do you live because the composition mixture at the pump can effect MPG at different times of the years.

Did you inspect your 2 H02's or scan the OBD port to see a code indicating a problem with the H02?

Quality of all parts varies with opinion. I recently tracked a common OE replacement electrical part and found it could have been assembled manufactured and packaged in several countries.

In the case of H02 or 02 sensor's many of us servicing many platforms find that either OE or Bosch seem to be better packaged quality over some aftermarket brands. (opinion)
