Redex specialises in high-quality fuel and engine additives engineered to keep modern and classic vehicles operating efficiently. Its range includes diesel and petrol fuel system cleaners, injector treatments, lead replacement additives, and AdBlue system protectors, each formulated to address common fuel-related issues such as injector deposits, poor combustion, reduced fuel economy, and increased emissions. Diesel-focused products are designed to clean injectors, improve combustion efficiency, and help lower exhaust emissions, making them suitable for both everyday driving and vehicles used predominantly on short journeys. Petrol system cleaners and injector treatments help restore lost performance, smooth engine operation, and improve fuel economy by removing harmful deposits from the fuel system. Redex also offers specialist additives such as lead replacement, which is essential for protecting valve seats in classic engines originally designed for leaded fuel, and urea/AdBlue system additives, which help protect SCR systems from crystallisation and contamination, supporting reliable emissions control. Suitable for a wide range of manufacturers and vehicle types, Redex products are easy to use, compatible with regular servicing routines, and designed to support compliance with modern emissions standards while extending engine and fuel system lifespan.
