I use castrol 4t 10w-40 full synthetic in all the 4 stroke quads and my Motorcycle with great results, I know the Blaster says 10w30 SAE. Can I use just regular motor oil? I use Mobil 1 full synthetic in my vehicles, is that sufficient? Just looking for a good all around oil that is easy to get at Walmart or autozone. I prefer synthetic so if there is a syn I can use in my blaster I would like to know. Thoughts?
