Synthetic 2-Stroke Injector OilAMSOIL Synthetic 2 Stroke Injector Oil reduces wear and maximizes engine life. Its high lubricity and reliable film strength help protect against piston scuffing and bearing wear. Strenuous conditions define the normal operating environments of snowmobiles and boats. Without the right lubrication, two stroke snowmobile engines and outboard motors run hotter, accumulate deposits and suffer a reduction in performance. AMSOIL Synthetic 2 Stroke Injector
