???? I am having a little trouble deciding what you are asking.

 

Your truck would be rated for 87 octane from the factory. But depending on your altitude you may be able to run 85.

 

In lower altitudes you won't even be able to find anything lower then 87.

 

My truck came from the factory tuned for 87 octane. I had Justin give me a 93 octane tune because he said he usually sees a little better mileage (which I don't really care much about) and 15-20hp more vs his 87 octane tune. That is on my 6.0 though, I don't know what the numbers would be on your truck.
