Replacing German Castrol 0w30 in small engines. Need recommendations

[Oil Changer]

There is no better oil for small air-cooled engines of all types than Amsoil's 10W30 small engine oil.

I ran small engine for a few years in ope. Now I run what ever is leftover. Currently Amsoil SS 5W30, before that M1 EP 5W30.
