O2 sensor results

Just changed mine out. I've read that it makes a major difference on gas mileage. I ran it today with a quarter tank and I really didn't see much of a change. do I got to give it a little more time? Swapped it out with one that I got from Advance

I guess it would make a difference if the original was faulty....otherwise there will be no noticable difference.
