1998 F-150 Oxygen sensor
I am by far from being a motorhead. But everytime I go into an auto parts store I always see Oxygen Sensors on the rack behind the counter. Now...I have an F-150 with 110,000 miles. I have spark knock that I cannot seem to get rid of without using high grade gasoline. Would replacing my oxygen sensor do any good for me? Would it give me better gas mileage? Or should I just wait till the check engine light goes on before I replace it? Also....where is the oxygen sensor located?

Welcome to FTE!
If you have a 5.4 you have 4 of them. They are located on the exhaust pipes behind the headers. They are easy to spot since you will see a probe stuck into the exhaust pipe at 4 locations. Usually a bad sensor will trip the check engine light. You can remove them and clean them up. They tend to carbon up and simple cleaning them off can sometimes help.
