Upper Cylinder Lubricant

Product code : UCLCN-EA

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.

Upper Cylinder Lubricant



Lubricates Top-End Components
The intense heat of combustion and limitations of the oil-control piston ring result in a lack of oil at the top of each cylinder. AMSOIL Upper Cylinder Lubricant's unique additives provide that missing lubrication to fight piston-ring and cylinder wear, maximizing engine compression and horsepower. Its lubricity improvers also aid in protecting fuel injectors and other fuel-system components from wear, helping ensure excellent performance and long-life. AMSOIL Upper Cylinder Lubricant delivers 18 percent more lubricity than Lucas* and 20 percent more than Sea Foam* for better retention of horsepower and fuel economy (see chart below).1

Lubricity Performance Graph

Inhibits Corrosion
Upper Cylinder Lubricant uses potent corrosion inhibitors to coat metal surfaces, block out moisture and stop deterioration before it starts. This is particularly important when using gasoline that contains ethanol due to its propensity to attract water and hasten corrosion. Inhibiting corrosion maximizes component life and reduces wear in the engine's top-end to guard against compression loss and maintain optimum power.

  • Lubricates fuel system and upper cylinders
  • Fights ethanol-related corrosion
  • Helps keep injectors clean
  • Compatible with capless fuel systems

Keeps Injectors Clean
Upper Cylinder Lubricant contains detergent additives designed to maintain injector cleanliness. While AMSOIL P.i. Performance Improver is designed to attack and remove stubborn injector deposits that can reduce power and fuel economy, Upper Cylinder Lubricant helps preserve injector and combustion-chamber cleanliness. Using it with every tank of fuel helps retain fuel-economy and performance gains and maximizes component life.

Capless-Compatible Packaging
Many new vehicles have replaced traditional fuel caps with capless systems. The threads on most bottles restrict them from opening the flap inside the fuel neck and make removing the bottle difficult. The AMSOIL Upper Cylinder Lubricant bottle is fully compatible with capless fuel systems. It's easy to insert, pour and remove the bottle.

RECOMMENDATIONS

  • For use with cars and trucks.
  • For best results, use with every tank of fuel. Do not refill tank until almost empty.
  • Treats up to 25 gallons. Add entire bottle to tank at fill-up.
  • Treat large gas tanks with two bottles of Upper Cylinder Lubricant. Using more than two bottles is not recommended.
  • Safe for use with catalytic converters, oxygenated gas and up to 15 percent ethanol-blended fuels. Do not use with E85 fuel.
  • Do not use with two-stroke or diesel engines.

    Great Product, Terrible Seal
    By  DEAN,  a  Verified Buyer  on  July 19, 2022
    I believe in UCL. When you think about highly-humified air sitting in the upper cylinder, cooling, and water condensation, UCL totally makes sense. Add to that keeping the valves clean and better gas mileage. Maybe why my Hemi has 71K and runs like day 1 with zero smoke?? I'm convinced. The bad part is the awful seal, hence the 4 stars. Why not a pull tab like was on these bottles for a short while...like every other sealed bottle in the world??
    Bottom Line
    Yes, I would recommend this to a friend.

    Works well as a supplement to PI Additive
    By  CHRIS,  a  Verified Buyer  from  New York  on  June 28, 2022
    Started using this product more regularly in between cycles of the PI additive. Have definitely noticed better maintained fuel mileage in between oil changes when using this.
    Bottom Line
    Yes, I would recommend this to a friend.
