[QUOTE="AlphaBob, post: 20141, member: 2158"] Tazza, Thanks for the quick response. I like the Castrol products and use 5W30 GTX in my autos.

The Kubota website says that 15W-40 can be substituted for the 10W-30 if 10W-30 can't be found, and 10W-30 diesel if pretty rare over here - Amsoil ($32 USD/gallon) is the only one I've identified to date.
