    The owners manual should tell ya. 87 is fine, some people run higher. The main thing is to run a quality fuel. Some stations have better gas than others. Try a few out, and see what your truck likes the best. :)

    Ventura Toyota, CA filled my tank with 89 before I left them. After using about half that fuel, I went to my trusty Chevron and added 91...and have been using 91 ever since. My butt dyno says its better =)

    My theory:
    Modern motors use knock sensors to retard timing when octane is low. I want maximum timing, so I use the highest octane available in my area. Also, Toyota motors were designed in Japan where they run 100+ octane fuel.
