For those of you who use AMSOIL's 100:1 premix - they have just announced a new product. Basically they seperated the premix for equipment and outboards - giving each new product specific product applications to better target specific engine types. The Saber Professional 100:1 Premix is now specifically designed for Chainsaws, Weed Eaters, Blowers, Mowers, etc. It is smokeless, recommended for ISO-L-EGD applications, and contains high temperature detergents for small power equipment with a lean mix ratio preventing plug fouling and exhaust port deposits. Whereas the Saber Outboard is low smoke, low odor, and contains lower temperature dispersants for water-cooled engines. AMSOIL will discontinue the old 100:1 premix when supplies run out.
