Does anyone run amsoil in their warrior and if so which weight are you running?

 

One of my friend used to sell Amsoil some years ago. He had a 500 four-strokes Bombardier Can-Am and raced it in winter time. His has no garage, so before he put 5W30 oil in it to be able to kick the engine. But at -20F, forget it. With Amsoil, I could start the engine with no problem because synthetic oil freeze at -40F only.

If your motor is in good condition, you can put 10W40, but if it is worn out, you can put 20W50. You will notice a slight power and RPM gain, this oil is that good.
