    not unless you have a supercharger. all the manuals spec the taco's on regular and older 2nd gen manuals stated that you could get minor performance gains running premium

    I run 89 and it does great, 93 for anything that puts stress on the truck such as towing, hauling, etc.

    Lots.
    91 or 93 only. It's worth the extra $0.20.

    Manual says regular...if the engine isn't tuned for premium, why waste the money? The computer will just retard the timing and/or adjust the air/fuel ratio effectively undoing any benefit you'd expect from premium. The only benefit I could think of is a cleaner burn and less knocking.

    I use regular and have had no issues in daily driving. If I were to tow something heavy I would consider putting in a higher octane.

    87.. 91 is not needed. It's not a high performance engine..

    wat?
    this is from an 07 manual....

    OCTANE RATING
    Select Octane Rating 87 (Research Octane
    Number 91) or higher.​
    Use of unleaded gasoline with an Octane
    Rating lower than 87 may result in engine
    knocking. Persistent knocking can lead to
    engine damage.​
    If your engine knocks...​
    If you detect heavy knocking even when
    using the recommended fuel, or if you
    hear steady knocking while holding a
    steady speed on level roads, consult your
    Toyota dealer.
    However, occasionally, you may notice
    light knocking for a short time while accelerating
    or driving up hills. This is normal​
    and there is no need for concern.

    Aren't all engines required by law to run on 87 octane? Not trying to stir the pot but just looking for confirmation.
