Redex Emissions Reducer can be used as often as required to bring down your car’s emissions. With its powerful cleaning formula, it can remove even the toughest deposits from your fuel injectors, for better long-term performance and engine health.
Rather than using Emissions Reducer all the time, however, we’d recommend combining it with other fuel additives in the Redex range. For example, why not use our System Cleaner for everyday engine maintenance, supplementing this with our Emissions Reducer every month and before your car is due to take its MOT test.
