I would stick with what the oil weight on the oil filler cap of your v-10 calls for. Ours on the Axis calls for 5-30. I use Mobil 1 full synthetic and have been using K&N oil filters. The generator specs by Cummins/Onan call for 30 weight in climates under 100 degrees and 15-40 for those over. 15-40 full synthetic is getting harder to find but I ordered a case on Amazon by Royal Purple. There are many others that offer "blends". As far as going with heavier weights for your v-10 because you are driving into a "hotter" climate, I don't make decisions like I did 40 years ago because I believe engineering has made enough improvements that I stick with the recommended oil specs. Many of the oil weights we used in our cars 40-50 years ago aren't even on the shelves anymore and there are some on the shelf that we didn't even think about.
