Assuming the truck has 89K on it, and the original oxygen sensor, I'd say the chances are good that it needs to be replaced. The sensor was only intended to last 60,000 miles or so. Worth a shot. I just replaced mine after 75,000 miles, and improved fuel mileage about 3 mpg. No trouble codes had been set, the sensor was still working, just not very well.

First of all, you made the right decision from a financial perspective by keeping the truck and not losing your rear on a trade-in. All of these things you mentioned may help slightly, but not enough to recover any amount that you paid to install them or have them installed. The most important thing you can do is always make sure your tires are properly inflated, make sure you keep up with regular maintenance (including tune-ups), drive the speed limits, and avoid jackrabbit starts. One thing that you also may want to consider will be to install a tourneau cover. Not only does this make your truck look nicer, it also prevents wind from creating a draft in your bed. Basically, it makes the truck more aerodynamic. If you don't like that idea, always make sure that your hatch is closed. I laugh at people who think that an open hatch increases gas mileage in a truck. It actually creates more downforce, which decreases mileage.

The following may squeeze a little more mileage out of your 350 but please don't expect miracles: When your next service interval comes due try switching the motor oil, transmission fluid and rear end gear lube to full synthetic oil.
I'd also jump on the band wagon and install a K&N air filter in your present "air box".
You can understand that your truck weighs nearly 5,500 lbs. and it takes a lot of horsepower to keep that much weight rolling along.
As other people have already stated OEM AC-Delco plugs and ignition wires won't hurt the situation either.

I am not sure if changing the oxygen sensor would help but keeping your air filter clean definetly will. I bought a K&N filter for my car and it has been terrific. My gas mileage improved some and my car actually seems to run better.

Get a K&N air filter. In my Chevy, it added 3 mpg.

I have been using a product for over a year that has increased my mileage by over 15% on the highway and a little less than that in the city.

Changing the Oxygen sensor MAY help, but it's not a guaranteed.
I would get a tune up, if you haven't already, top off all of your fluids, and get a different air cleaner (I suggest K&N)
