I plan to use the Castrol Edge in my 1025 because it's the only xw30 oil that I can get that's diesel rated. Every other diesel rated oils available around here (and even in Ohio where I checked some) are xxw40 oils. My temperature chart shows I don't need a 30w, and I want to save fuel by using xw30. Going to 0w20 in my Tacoma has really improved the fuel mileage on it.
Amsoil (I don't sell the stuff) has a CJ-4 10W30, and a pre-emission 10w30 and 5w30. I don't remember the spec you need for that engine.
