26’ Hurricane SO fuel

Mine doesn’t say that! And sticker says 87 octane.

I believe it’s always bank 2 rich to lean. I have tried other gas stations 87 & 89.

Now it’s not been coming on last few weeks using same Meijer brand 93 octane. After this tank runs dry I’m gonna put some 87 back in and get light then take to dealer and make sure it’s same code then run some 91 or 93 and make sure it goes out. If it does then I’m taking truck back in. I feel it’s the computer.

I just posted pics of my spark plugs at 65k on my SO today—swapped them yesterday.
I ran 87octane top tier 80% of the time.
My post should be close to the top still.

If you’ve got access to E85, throw a few gallons in it next time you fill up. You’ll find out if your issue is cause by octane level
Odd that the dealership told you to use octane booster, when the manual specifically says not to
