Tested in the lab to ensure quality and guaranteed to perform, our gasoline is formulated with powerful deposit control additives that deep clean engine components to restore the best possible engine performance and keep it running like new.
Everyone wants their vehicle to start promptly, accelerate quickly, and idle smoothly. A clean engine will most likely run like new and testing shows that Kirkland Signature™ Gasoline cleans up dirty engines and keeps them clean.
The clean-up of existing deposits and fuel injectors can restore mileage lost to dirty engines. Regular use of Kirkland Signature™ Gasoline promotes consistently clean engines, helping to restore an engine's intended fuel economy.
Removing deposits allows the engine's sophisticated emissions controls to work as designed, helping to reduce tailpipe pollution caused by intake valve deposits and plugged fuel injectors.
Deposit control additives prevent new deposits from accumulating by forming a protective molecular layer on certain critical engine parts. This increases vehicle reliability, lowers maintenance, and helps extend engine performance.
