How Sea Foam Fuel Injector Cleaner Works
Sea Foam Fuel Injector Cleaner works by targeting the residues that accumulate in fuel systems over time. When fuel is burned in an engine, incomplete combustion can leave behind carbon deposits, which cling to fuel injectors, intake valves, and combustion chambers. These deposits restrict fuel flow, reduce injector spray patterns, and hinder engine efficiency. Sea Foam’s active ingredients penetrate and dissolve these deposits, allowing them to be safely burned away during normal engine operation. The process begins as soon as the additive mixes with fuel, where it circulates through the fuel lines and injectors. As it passes through, it cleans the tiny nozzles of fuel injectors, ensuring a precise and consistent fuel spray. This restoration of proper fuel delivery leads to smoother idling, better acceleration, and reduced emissions. Additionally, Sea Foam contains lubricating properties that help protect fuel pumps and injectors from wear, extending their lifespan.
