  1. 87 octane causing problems?

    Problems & Troubleshooting
    When I bought my RL no one told me I had to use 91 octane or higher. Its my first high performance car and I didn't know any better. Shame on me yes haha. But my question is... Because the lower than recommended octane fuel will ignite before its where it needs to be inside the engine, i know it...
