I bought sthil ultra ..I understand pezoil is good and though I know nothing about it another name dropped is a product called royal purple.I do know that most experts will tell you to stay away from amsoil!I enjoy working with valleyview and they are big fans of sthil..this also my first gasser but certainly not my last.I am getting advice to use 89 octane as it has a little less etnanol.
