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.

    Improvement
    By  ARMANDO,  a  Verified Buyer  on  September 13, 2021

    Describe the issue

    I purchased a case and have been very satisfied as both my vehicles are running great. However, my shipment showed up with an oil stain and when I opened the box I found one of the bottles cap was loose with seal broken and the fluid leaked all over the box. Then found a few more bottles with loose caps but the seal still intake.

    Use it for the first time and really helped my mileage. Went from 6l per 100 kms to 5l. Made to Montreal on 3/4 of a tank, normally use a whole tank from Hamilton. Same for my wife’s Outback. So much better than Sea Foam.

    Yes, I would recommend this to a friend.

    Simply the best: Tested! Tried! & True!
    By  RANDALL,  a  Verified Buyer  from  Rusagonis, NB  on  September 06, 2021

    Describe the issue

    Truly an amazing product. At first I was apprehensive about this product. After purchasing, my son just purchased a 2014 Rogue. He was telling me he needed to take vehicle to dealer, he was concerned of a hesitation around 30-60kms. Dealer did updates and hesitation still persisted. He was taking it back and asked me to go. Unknown to him I added a bottle to his vehicle. He could not get over the difference. It actually cured this hesitation his vehicle was experiencing. Both of us ride touring bikes and use this product regularly. It makes an incredible difference. We can actually hear the smoother engine idle from using this and other Amsoil products.
    Bottom Line
    Yes, I would recommend this to a friend.

    Describe the issue

    Wanted an upper cylinder lubricant that didn’t effect gas mileage. So far, I don’t see a mileage difference from use/non use. Using at every fill up.
    Bottom Line
    Yes, I would recommend this to a friend.
