Do not purchase champion syngold from Auto anything. It is not the European low saps formula that meets Chrysler spec though it shares the same bottle and weight. Auto anything sells champion oils part number 4431. 4436 is spec for the truckKendall seems pretty popular.
Alternative the penzoil or liquimoly which are the cheapest available oils,
On the higher end of the spectrum is the Mobil 1 ESP.
I personally run champion syngold from Autoanything. They provide a little better price than advertised for me and I've had no oil related issues. It's about $80 for me to change the oil
