I am curious what everyone is running for oil. I have been running mobil 1 high mileage synthetic with a mobil 1 filter, but I am looking for something else to try. I have got a slight whine in the motor somewhere, and I have heard that some have been able to remedy the noise (superficial but drives me nuts) with a different brand or weight oil. I love how easy it is to change the oil on these 4.0s and I usually change every 5k miles. I have a 04 limited v6 with 160k and it runs great!
