The ITW Full Throttle Diesel Fuel System Cleaner, No. FT20100 is a one-tank, multi-functional formulation designed to clean the entire fuel system. It helps to restore lost power by cleaning fuel injectors and breaking down carbon buildup throughout the entire fuel system. The Diesel Fuel System Cleaner removes carbon deposits on valves and injectors, diminishes black smoke through combustion catalysis, and improves lubricity for better fuel economy. It also enhances cold flow properties and reduces emissions, says the company.
