Archoil AR6700-D is a complete diesel cleaner engineered to clean, protect, and maintain the entire diesel fuel system in a single tank treatment. The 250ml bottle treats a full tank of diesel (minimum 40 litres), delivering multi-action cleaning and protection from injectors through to the exhaust. Modern diesel engines accumulate carbon deposits over time, particularly from short journeys, stop-start driving, and ultra-low sulphur diesel. These deposits build up in the fuel injectors, combustion chamber, turbo, DPF, EGR valve, and catalytic converter, leading to reduced performance, increased fuel consumption, rough running, and rising exhaust emissions. Left unaddressed, these deposits can trigger warning lights and MOT failures.
