AMSOIL Gasoline Additives

AMSOIL Gasoline Additives, 1 New, 1 Reformulated

AMSOIL P.I and Upper Cylinder Lubrication Gasoline Additives

AMSOIL GASOLINE ADDITIVES HAS INTRODUCED A NEW UPPER CYLINDER LUBRICANT AND REFORMULATED AND REDESIGNED THE BOTTLE FOR THE AMSOIL PERFORMANCE IMPROVER TO WORK EVEN BETTER IN GASOLINE DIRECT INJECTED ENGINES.

Let’s start with the new AMSOIL Upper Cylinder Lubricant (UCL)

Upper Cylinder Lubrication Gasoline Additive

Upper cylinders are one of the toughest areas of an engine to lubricate due to the intense heat of combustion and the design of today’s vehicles. New AMSOIL Upper Cylinder Lubricant delivers a much-needed layer of protection to this trouble area to help fight piston-ring and cylinder wear, maximizing engine compression and horsepower. Its lubricity improvers aid in protecting fuel injectors and other fuel-system components from wear, helping ensure excellent performance and long life.

Plus, it really works. 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.1

Inhibits CorrosionUpper 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.

Keeps Injectors Clean

Upper Cylinder Lubricant contains detergent additives designed to maintain injector cleanliness. It’s designed to work in concert with AMSOIL P.i. Performance Improver (API) to maintain injector and combustion-chamber cleanliness, retain fuel-economy and performance gains and maximize component life.

Capless-Compatible Packaging

The AMSOIL Upper Cylinder Lubricant bottle is fully compatible with capless fuel systems. 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 also make removing the bottle difficult. Our packaging makes it easy to insert, pour and remove the bottle.

AMSOIL Performance Improver Gasoline Additive

AMSOIL PI Gasoline Additive

AMSOIL Performance Improver has been reformulated to work even better. See this study on the old formulation

AMSOIL P.i. is a potent, deep-cleaning gasoline performance improver featuring concentrated detergents that aggressively clean stubborn, power robbing deposits from injectors, valves and combustion chambers. It reduces emissions and increases fuel economy up to 5.7 percent.1 P.i. cleans your entire fuel system and restores your engine’s power and performance in one tank of gasoline. The P.i. bottle is fully compatible with the capless fuel systems of modern vehicles for easy application.

  • For use in gasoline powered cars and trucks.
  • Treats up to 30 gallons. Add entire bottle to tank at fill-up.
  • For best results, clean your fuel system with P.i. every 4,000 miles.
  • For large gas tanks, treat with two bottles of P.i. Using more than two bottles per treatment is not recommended.
  • Safe for use with catalytic converters, oxygen sensors, oxygenated gas and up to 15 percent ethanol blended gas.
  • Do not use with diesel or E85 fuel or two-stroke engines.
