They recommend 89 octane as a minimum (it's in your manual) but I run 91 for my tune. If I find 93 I get it.

I was using 89 or premium (since sam's club doesn't carry midgrade) when I first got my truck. I switched to 87, and haven't noticed a difference in power or fuel economy.

Just ordered a predator though... haven't decided if I'm gonna use the 87 or the 93 tune yet. I'll probably try them both and see what happens.

The manual recommends 89 and says there is no benefit with 91. I have been running 87 and cannot tell a difference at all.

I didn't notice much running 87, but once I put the predator tuner on it I needed to up the octant to calm the knock that I arose from the lower grade fuel.
