Actually, I already was into the purchase when I noticed the Premium only restriction (which mine does have)and kind of freaked out. But the owner I bought it from said he had never used it and had no problems. I have put only 87 octane in it since then and never had an issue. I don't even hear knocking...

I do wonder how much more umph it would have w/ premium or if the mileage would improve, but when I stomp on the gas the 5.9L really throws me back, so I have enough get-up-and-go already. (Though I hardly everstep down on the gas too much given the gas costs right now)

As far as mileage- I'm already getting about 14 and from what I've seen that's as good as it gets unfortunately...
