You will never go wrong with a fresh oil change before haul out for winter storage. Just make sure the engine is warm before you drain it and then run it up to usual operating temp to circulate the new oil before you shut down for winter storage. Shell Rotella is very good oil. I would advise to use a non synthetic. And you will never go wrong with a filter change either so by all means yes change it when you change the oil. Choose a good rated filter. I use NAPA gold on my Universal M4-30 diesel and a multigrade diesel lube oil from Canadian Tire or Walmart. Something like 15w-40 will be just fine.
