    What is the recommended octane level for the 5.0 engine.

    My Car didn't come with a instruction booklet so im not sure if it supposed to take premium or not. So ive been putting in regular.

    I don't what over pay for premium if its a waste. could you help me out?

    Unless your car pings with 87 at 10 degrees. My 94 at 6 degrees would ping with 87. With 93, or 94 i can run between 10-14 w/o a problem
