I don't use a synthetic, I use Delo 15W40 which is similar to Rotella 15W40, my climate is very mild with but a day or two below 32 deg. For my needs, it works fine but I also understand that the colder climates will indeed benefit from a synthetic especially if your like me and just get going with very little warm up time. There are more benefits to synthetic then just that but I am pretty sure many other things will be pretty well worn out on my tractor before the engine. If Rotella is not available in a synthetic and you would like to experiment with a synthetic, I would still consider a 15W40, I think there are some name brand synthetics in the 15W40 viscosity that would be fine. Amsoil is certainly a consideration as well. My Kubota manual says to use 10W30 or 15W40. I've read where the new 5WXX is the new way for diesel oils but will wait until the manufactuer suggests it. They did a pretty good job designing everything else so I don't think I will second guess them on oil recommendations.
PS I experimented with Redline 10W30 but that lasted one change. It is a synthetic oil and costs $8 a quart. I use 6.5 quarts per change so it was not a huge investment, but still more then I wanted to do continuously. It definitely was different then the standard "dino" oil, smell, feel, taste (kidding) but whether that was good or not, I am not sure. I've also used Amsoil 15W40 which at half that cost may well be in your best interest if a synthetic interest's you.
