Amsoil 20w-50 or m1 15w-50

I purchased a Triumph speed 4 a few months ago, and they and the dealers specify to use the Triumph oil made by Mobil 1 that is a 15w-50 viscosity. It is different than the "Gold cap". The viscosity at 100f and 212f match that of Amsoils 20w-50. 152cst and 20.7cst. The Gold cap is 138cst and 18.0. So they way it looks i can safely use the Amsoil 20w-50 because it matches axactly. Does this sound right?

Amsoils 20w-50 4-stroke motorcycle oil will work great.

The Amsoil will be fine. What about Mobil's MC oils? They are among the best out there.

Eather Amsoil or M1 will work great,i use Amsoil (MCV)20w50
in my Yanaha ATV, because she runs HOT..

Use either one......go with the least expensive because both are excellent. I like the M1Vtwin20w50 in my Harley.
