Well I went to the dealer today and they said all my O2 sensors and basicly everything that has to do with it was bad. Parts will be here tomorrow morning and it'll be done by the afternoon. Im wondering if they went bad at 5400 miles cuz of the gas I run. Iv always ran marathon but the one I goto is always 5 or more cents cheaper then every place around me.

They were definitely contaminated from something.. My vote would go to the fuel treatments, because I've never heard of bad gas completely ruining o2s that fast, but it wouldn't be a bad idea to switch stations. All the o2s going bad by themselves like that is impossible, so there's probably a reason, so I'd definitely change those two things. What brand/type of additive were you using?

The only fuel treatment I will use is BG 44k. It's been used for years and I know it works and won't damage vehicles when used correctly. Just follow the directions that come with it.
I think fuel is pretty regulated these days. Most of the time when I see problems with fuel it has to do with the age and location of the actual gas station. I know of one place that where the pumps and tanks are in the ground is a lot lower than the surrounding areas and I know of 3 people who have gotten bad, sputtering gas from there, which usually means there's water in it, and because all the water around there would run down and sit right on the pumps and tanks it makes sense. Also older stations are more likely to have gunk in their tanks and leaking seals and all which would make you more likely to get bad gas there. I have tons of gas stations on my way home from work, at least 20, And my favorite is a Shell that sits on high ground and was just built last year.
Your truck isn't tuned to burn anything but 87 and if yours is FF E85. Running anything else is worse and will cause a whole lot more carbon build up. The higher the octane the more heat it takes to burn the fuel completely, which would be ok if your engine was tuned to run the higher octane, it would have different ignition timing and spray a different amount of fuel, since it thinks it's burning 87, when you spray 93 the fuel isn't completely burnt which sends a bunch of raw fuel out the exhaust, it gathers on the valves, O2 sensors and cats, and will really do some damage. People always think higher octane burns "hotter" or "cleaner" and nothing could be further from the truth.

Nah, nothing will be damaged. I'm sure there are other brand additives that work ok, I just personally like the BG stuff. And I forgot you have the tuner, so that changes most of what I said for you specifically. It's still true, but since you were actually tuned for it the fuel should have been burning correctly. I feel like I keep scaring you into thinking your truck is broken haha, I don't mean to, just trying to throw some information out there that I've seen cause people trouble before.
