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.

    More MPG's!
    By  Billy,  a  Verified Buyer  from  VA  on  May 23, 2021

    Describe the issue

    I put a bottle in every tank full of gas because it adds about .3-.6 MPG in my 2018 5.7 RAM. To me if it's adding lubricity enough to add MPG's it should add extended life to the engine as well!
    Bottom Line
    Yes, I would recommend this to a friend.

    Upper cylinder lubricant
    By  TERRY,  a  Verified Buyer  from  Maryland  on  May 21, 2021

    Describe the issue

    Great product. Use it every fill up. Cheaper than store bought products. Only issue is the opening of the seal. Sometimes the tab pulls off and you have to use a finger to break the seal. Seal needs to be made like performance improver so the solvent doesn’t get on your hands. Great product other than that.
    Bottom Line
    Yes, I would recommend this to a friend.

    Use on Bike trips
    By  DAVID,  a  Verified Buyer  from  My Garage  on  May 21, 2021

    Describe the issue

    I use this on long bike trips when the temps are high to help keep the top end of the engine lubricated. I add 1.5oz to a tank of gas (5 gal) maybe every 2 or 3 tanks. About 1 bottle every 8 to 10 tanks of gas.
    Bottom Line
    Yes, I would recommend this to a friend.
