I've been using Amsoil 15W-40 Heavy Duty and Marine oil in my X595 Yanmar diesel. The 15W is too high for my climate (Wisconsin). I do run it a lot in the winter for snow plowing. I believe the Amsoil premium 5W-40 API CJ-4 is the best choice from Amsoil to use for my tractor. Let me know if something else is a better choice. I'm just not sure about the CJ-4 as my tractor is a 2003, but I believe its backwards compatible. I'm only interested in Amsoil as I've been using it for years with good results.
