    Same boat here, first non diesel truck, period! Lol
    Driving it off the lot I felt a tad bit of hesitation on certain speeds while accelerating. I had a Porsche 997 Turbo with an EVT tune that did that in the heat.
    I believe reading the manual it says that 91 or higher renders better performance.

    Your truck your choice. I tried 87 for a few tanks and it seemed fine. Switched to 93 and it generally felt better. Havnt put anything but 93 in the truck since.

    I used one tank of 87, but I have been running nothing but 93 since. I am getting ready to do the MPT 93 PRX tune next week, so I will continue to use 93 from this point forward.

    1. Congrats on the truck.

    2. You can start a mile long debate over this subject. Check your glove box, read the manual, minimum 91 = minimum 91. End of story.

    I notice hesitation on acceleration too even on 9 octane. I was assuming it was traction control kicking in but now I'm thinking its knock. Going to change to the Motorcraft 542 plugs. From what I read here they seem to fix the issue like the Denso plugs did for tuned 997tt's

    Will that void the warranty?? Could these plugs be ordered from the dealer?

    Owner's manuals are useless. They should just stop putting them in cars and tell people to refer to their website for an online version, or refer to a forum of their choice.

    Are you sure it's not the turbo lag you're feeling?
    New spark plugs will be useless if it is!

    You can use 87 or anything higher. Your truck will pull power (retard timing etc) with low octane fuel. The truck will have more power with better fuel.

    Runs fine on 87. Just like the manual says it will.
    Over 15,000 miles. No issues.
