Switching to Amsoil, should I go 20-50 or 10-40? Just let me know, and if you don't mind an explanation. Thanks ya'll.

use 20-50 Victory stock oil is 20-40 >>>>you will just fine with 20-50

Either will be fine. With the 20 it will be harder to start in the cold, but the 50 is better in the heat. I asked same question to mobil one customer service and they said either but recommended the 10w40

I use the 10w-40 amsoil, it's what amsoil recommends.
