I have an Ariens 17.5 HP (single cylinder B&S 31000-series engine) rider that I use as a yard utility vehicle. It gets used year 'round for getting the mail and various other tasks. That means lots of short trips on anything from 100-degree summer days to 5-degree winter mornings. It occasionally gets a couple hour run time if I'm doing something like picking up sticks or spraying for bugs. I used to use 10W-30 dino oil but noticed it seem to accumulate a lot of moisture due to the short run times and it was a bit sluggish turning over in winter. So two years ago I switched to Mobil-1 5W-30 full synthetic and have had no problems. I have no measurable oil consumption during hot summer days, it cranks much easier in winter and for some reason I seem to get less condensation in the oil.
It depends on your ambient operating temperatures. For the Kawasaki FS730V used in the X500 the OEM Kawasaki owner's manual has this oil chart:
The John Deere owner's manual for the X500 has the following oil chart:

I use EXACTLY what Kubota recommends in my 2009 Op Manual. 15W-40 year round. I initially used Kubota branded oil but have now switched to Shell Rotella. I can get Rotella at the local NAPA store.

All my diesels get either Rotella or Delo old school 15w40. Both are fine oils and I go with which ever is lower in price at the Wally. The motor internals will outlast me. And be in fine shape for the next owner or two. I own or have owned equipment with 5K to 8K hours on them that have had regular oil inserted in them for their lifetime, and they still run fine without any noticeable engine wear. I do use syn oil in my Zero turn and generator.
