Hi all!
I'm new to the forum and brand new to being a truck owner (very happy so far.)
What octane fuel are you putting into your vehicles? Are there any real advantages in going 89 vs. 87, 92 vs. 89?
Dealer filled the truck with 87 after I purchased and I'm not seeing great results with regard to mpg (averaging 13.3 over 100 miles, mixed hwy/fwy, and relaxed style driving)
Thanks in advance for the input/advice!

Higher octane will yield slightly more power but your mpg will not improve. 3.31 gears?

Look in the manual. It states to ignore mileage untill break in is over. It will increase substantially.
And second as with all turbo engines the best performance will always be with 93. Less knock under high pressure nets higher gains. Does not have to mean high rpm just high boost. So even going up a hill and not shifting out of 6th is a gain in performance. And most report small gains in mpg as well.
Side note welcome to the forum... The search function is your friend. This topic has absolutely been beat to death. All that really means is most things you want to learn about are already discussed.

what octane does your owners manual call for?

I'm in Tucson, Arizona and only run Shell or Chevron in mine, but mainly Shell. I run 87 in mine, but about every 3rd or 4th fill up, I run the supreme in her, but as far as the manual goes it calls for 87.

You can feel the difference between octane levels. When I put my truck to 91 I felt the difference and even between 91 and 93 I felt the difference as well. Seemed a little more responsive and just had less "noise" I guess you could call it. MPG's went up so slightly that it doesn't come close to paying itself, but hearing a more sound engine and knowing that it's liking it a bit better makes it worth the cost. You could throw in a performance tune too and REALLY feel the power!

Run 87 octane for regular every day driving and 92-93 when you're towing as per the owners manual. No additional benefit will be gained by running higher octane every 2-3 tanks if not towing. That belief was probably derived from the myth that higher octane fuels contain more detergents and run cleaner.
