The John Deere MC38566F Diesel Conditioner is a genuine 1.9-liter fuel additive designed to treat up to 1000 liters of diesel fuel. This advanced formula optimizes fuel economy, increases power, and reduces harmful emissions. It effectively cleans fuel injectors, prevents rust and corrosion, and improves cold weather starting. The conditioner also stabilizes fuel for storage, extends fuel filter life, and lubricates critical fuel system components like the fuel pump and injectors. Free from alcohol, it is safe for all diesel engines, including those equipped with common rail injection systems and Diesel Particulate Filters (DPF).
