Auto Zone has Valvoline ATV oil in 10w40 down here in the south. Pep Boys Auto has it also in both 10w40 & 10w30 as well. Ck the owners manual for your temp chart for you location. Valvoline is the only one I've seen that has ATV oil for this application. So, Valvoline 10w40 for the summer & 10w30 for the winter it is!!!
There is no gear oil in it. The motor oil does every thing. Use 10w-40 Oil
10w-40 motorcycle or ATV oil will work just fine.
0W-40. There are many that are formulated just for atv's.
USE Synthetic ATV OIL, it comes in various weights. Valvoline makes it, but Lucus makes a good oil but it is 8 to 10 dollars a quart.
