AMSOIL Upper Cylinder Lubricant Corrosion Inhibitor
Preserves Horsepower and Performance
Your engine’s top-end is sparsely lubricated and prone to the development of performance-robbing deposits. It’s also highly susceptible to corrosion, an issue compounded by the prevalence of ethanol in today’s fuel. AMSOIL Upper Cylinder Lubricant is designed to solve those issues. Its AMSOIL-exclusive, powerful formulation helps maximize engine power and performance while increasing engine life. And unlike competing fuel additives, AMSOIL Upper Cylinder Lubricant works (See chart above).
- Lubricates fuel system and upper cylinders
- Fights ethanol-related corrosion
- Helps keep injectors clean
- Compatible with capless fuel systems
AMSOIL Quickshot® Gasoline Treatment & Stabilizer
Formulated to Restore Peak Performance in Small Engines and Powersports Equipment
Degraded fuel presents a major maintenance issue in small engines and powersports equipment. It can form varnish, gum and insoluble debris that clog carburetors, fuel injectors and fuel filters. Carbon buildup can form on the tops of pistons, causing 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 is a premium fuel additive formulated to thoroughly clean and restore peak performance in small-engine and powersports equipment fuel systems. It also stabilizes fuel between uses and during short-term storage. Its revolutionary technology focuses on three major fuel-related issues plaguing these applications: ethanol, water and dirty pump gas.
- Cleans powersports fuel systems
- Addresses ethanol-related performance issues
- Stabilizes fuel during short-term storage
AMSOIL Gasoline Stabilizer
Formulated to Resist Gasoline Breakdown
For maximum convenience and cost-effectiveness, equipment and vehicles used seasonally, such as motorcycles, snowmobiles, personal watercraft, snowblowers, outboard motors and classic cars, need to start easily and run properly when removed from storage. Gasoline, however, is not formulated for long-term storage and can start to degrade in as little as 30 days. Degraded fuel leads to varnish and sludge that clog injectors, fuel lines and carburetors; stick floats; and cause poor engine performance, starting problems, increased maintenance expenses and decreased equipment life.
AMSOIL Gasoline Stabilizer inhibits the oxidation process that occurs when fuel is stored for extended periods, improving performance, helping extend equipment life and decreasing maintenance expenses.
AMSOIL Gasoline Stabilizer delivers 8X longer fuel stability than Sea Foam® Motor Treatment in the triple-length gasoline oxidation stability test (ASTM D525), helping maintain startability and protect against the formation of varnish and gum.Z
- Helps keep fuel fresh up to 12 months
- Protects against varnish and gum buildup
- Fights ethanol corrosion
- Ideal for stored seasonal equipment such as snowmobiles, lawnmowers, motorcycles and boats
