Upper Cylinder Lubricant

Product code : UCLCNC-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.

    By  KENNETH,  a  Verified Buyer  from  FL  on  June 25, 2022
    I have been a Preferred Customer for years. Using Amsoil products saves time and money vice having all of ths work done at a shop, and especially at a dealership. I have a long drawn story I tell people all of time about how I discovered Amsoil and why I have these products for so long. Just not enough room here. I enjoy and trust Amsoil products in all of my vehicles and equipment. 2 trucks with over 250, 000 miles each that I owned for 14 years each and working on third, plus my wife's cars and kids vehicles and 6 grown grand kids (hopefully I will be around to help some of my great grandchildre of which I have seven.
    Bottom Line
    Yes, I would recommend this to a friend.

    Great Little Product.
    By  Tracy,  a  Verified Buyer  from  Kentucky  on  June 06, 2022
    Upper cylinders on a lot of vehicles don't get the lubrication they need with ordinary fuel treatments. I've used this for several years now, and notice my vehicles run smoother and respond better prior to have not using this product.
    Bottom Line
    Yes, I would recommend this to a friend.

    Combustion Chamber Aid
    By  Old Guy,  a  Verified Buyer  from  Bethesda, Md.  on  June 02, 2022
    I recently learned about this product from online videos. I hadn't thought about the fact that from the middle piston ring on up, there is no effective lube in the combustion chamber. The rings keep the oil below this area. I merely pop a bottle of Upper Cylinder Lube in at every fill-up, and I figure I am good to go. As this product also helps keep your fuel injectors clean, you can't lose!
    Bottom Line
    Yes, I would recommend this to a friend.

    Best of the Upper Cylinder Lubricants
    By  TIM,  a  Verified Buyer  from  SC  on  May 09, 2022
    This the second time I've been asked to review. I have used this for about two years in a 3.5 Duratec engine. One of the benefits of this products has been a .3 mile per gallon increase mileage outside of other stated benefits. Mileage drops .3 to .5 miles per gallon when not added at fill ups. My wife drives this vehicle which I feel up, so its not me increasing the mileage. It doesn't leave any noticeable residue on the end of the tail pipes (unlike another brand I've used in my pick up truck). My intention for using this product is to increase the life of this engine and its efficiency. So far it its working as intended.
    Bottom Line
    Yes, I would recommend this to a friend.
