These deposits reduce e\x1dciency, disrupt spray patterns, and ultimately impair combustion stability and fuel economy. Additionally, it is common for water accumulation in fuel systems over time due to a variety of factors. This can result in corrosion of fuel lines, injectors, and sensitive components, further compromising performance and reliability.Key Functions: Improves fuel economy by dissolving carbon and oxidized fuel at the injectorDeposits at injector nozzles reduce fuel atomi-zation, disrupt spray patterns, and compromise combustion e\x1dciency. The Fuel System Clean uses modern detergents to dissolve these deposits, restoring proper injector performance and improving fuel economy. Chlorine-free and alcohol-free to protect seals, gaskets, and O-ringsUnlike solvent-based cleaners, this formula avoids materials that can degrade gasket and seal materials, making it safe for long-term use across a wide range of fuel system components. Removes moisture from fuel systemModern pump gasolines often contain ethanol, which is hygroscopic and can lead to phase separation, corrosion and excess fuel pump wear.
