CATACLEAN ADDITIVES £15.99

Endorsed by pro mechanics as a ‘little bottle of magic’, this eight-in-one, pour-and-go fuel additive cleans, restores and protects a car’s engine, fuelling and exhaust system. Blitzing resin and carbon deposits from injectors, valves, DPF, catalytic converter and exhaust, it can reduce emissions by up to 60 per cent, and improve mpg, bhp, torque and throttle response. cataclean.com
