Might be running a tad rich whickh is common for a factory tuned engine. The octane really does not matter. dodge stated to use 89 because supposedly it is a cleaner fuel. Stick with the 87 if it is running fine on it. 2 more octane points is not going to make or break this engine. The 5.7 uses a lot of gas, especially when you step on it. If you have the EVIC, watch the real time mpg display drop to zero when you nail it. I would not sweat it. Just tell your buddy to enjoy the smell of a real engine!
