Reduces Emissions

Removing deposits allows the engine's sophisticated emissions controls to work as designed, helping to reduce exhaust pollution caused by valve deposits and plugged fuel injectors.

Helps Restore Fuel Economy

Deposits on injectors can affect the fuel spray pattern and timing which prevents good combustion. Kirkland Signature Fuels fight existing injector deposits and prevents new deposits from forming.


Clean fuel injectors provide maximum fuel flow and a fine spray that helps create efficient fuel combustion. Regular use of Kirkland Signature fuel promotes consistently clean engines, helping to restore an engine's maximum fuel economy.


Fights Harmful Deposits

Use of Kirkland Signature Unleaded or Premium Unleaded 97 helps to remove existing deposits on petrol engine intake valves, and prevents new deposits from forming. This increases vehicle reliability, reduces maintenance, and helps create optimal engine performance.


Improves PerformanceCleaning additives restore power by removing deposits from fuel injection equipment and prevent future build-up that can cause power loss and affect driveability.
