Just recently my gas consumption has skyrocketed, at first I thought someone had been ciphening my tank. Could it be the 02 sensors? It's a V8.

Do you have a check engine light on? I've had this problem, but it came with a check engine light and ended up being the thermostat.
Yes the check engine has been on since I bought it a year ago, it was checked at the dealership but they told me it wasn't a big deal, that it was a sensor or something, it has run great but just recently the gas consumption issue.
Five will get you 10 that the problems are related. You got horrible advice at the dealership . . . if you've got that documented, maybe use it against them. Take the truck to a shop for a full diagnosis. I'm worried that letting it go could damage expensive components, like the catalytic converter. http://repairpal.com/check-engine-light
