The Liqui-Moly Diesel Particulate Filter Protector is a high-performance fuel additive engineered to prevent soot build-up and extend the service life of diesel particulate filters (DPFs). Ideal for vehicles that operate under short-trip or city-driving conditions, this formula supports continuous DPF regeneration, helping avoid costly repairs, reduced performance, and unnecessary downtime. By promoting cleaner, more efficient combustion, this additive reduces particulate formation, lowers emissions, and keeps the DPF functioning at peak efficiency. Regular use ensures long-term protection, improved reliability, and smoother engine performance for modern diesel vehicles.
