AMSOIL Ea Synthetic Oil Filters

AMSOIL Absolute Efficiency EaO Oil Filters with Nanofiber Technology AMSOIL Ea® Oil Filters (EaO, Ea15K) have one of the best efficiency ratings in the automotive/light-truck market. Ea Oil Filters provide a filtering efficiency in accordance with industry standard ISO 4548-12 of 98.7 percent at 20 microns, while competitive filters demonstrate efficiencies as low as 51 percent. Their small synthetic fibers trap smaller particles and hold more contaminants, resulting in lower restriction. During cold-temperature warm-up periods, an Ea Oil Filter allows the oil to flow through the filter more easily than a typical cellulose filter does. Lower restriction decreases engine wear. AMSOIL Ea Oil Filters have a greater capacity for small, wear-causing contaminants than competing filter lines. When used in conjunction with AMSOIL synthetic motor oils, AMSOIL Ea Oil Filters are guaranteed for up to 15,000 miles/one year, whichever comes first, or 25,000 miles/one year, whichever comes first, depending on application and severity of service.

Summary

New! AMSOIL Quickshot SE

AMSOIL Quickshot SE Restores Peak Performance in Small Engines and Powersports EquipmentThe premium fuel additive to thoroughly clean and restore peak performance in small engine and powersports equipment fuel systems. Degraded fuel presents a major maintenance issue in small engines and powersports equipment. AMSOIL Quickshot SE’s revolutionary technology focuses on three major fuel-related issues plaguing small engines and powersports equipment: ethanol, water and dirty pump gas. They can form varnish, gum and insoluble debris that clog carburetors, fuel injectors and fuel filters. Carbon buildup can form on the tops of pistons that leads to pre-ignition, rough idling and poor throttle response. Fuel-related problems are only expected to intensify in the coming years as the ethanol content in pump gasoline continues to increase. AMSOIL Quickshot SE also stabilizes fuel between uses and during short-term storage periods.

AMSOIL Diesel Concentrate
Summary

AMSOIL Diesel Concentrate

AMSOIL Diesel Concentrate Diesel Fuel AdditiveAMSOIL Diesel Concentrate has been reformulated with additional lubricity properties to address the issues involved with Ultra Low Sulfur Diesel (ULSD) Fuel. The new AMSOIL Diesel Concentrate is a total system cleaner and lubricity improver for all types of diesel engines, including automotive, light truck, heavy duty and marine applications. AMSOIL Diesel Concentrate compensates for the quality variances of different fuels (including biodiesels) and the deficiencies of today’s ULSD for better engine operation. The Environmental Protection Agency (EPA) mandated major changes for Ultra Low Sulfur Diesel fuel (ULSD), bringing the sulfur content to 15 ppm, a staggering drop from the previous requirement of 500 ppm. Lower sulfur means lower lubricity, the property that controls wear in the fuel injectors and fuel pump. AMSOIL Diesel Concentrate is recommended for use with all types of heavy and light-duty, on or off-road diesels and marine diesel engines. The recommended mix ratio is one oz. of additive per five gallons of fuel.
