Over time as you drive, deposits build up on your injectors and in the fuel system, and this reduces combustion and increases emissions. This is one reason why older cars usually have higher emissions than when they were new. Redex Emissions Reducer cleans the system and gets rid of the dirt that contributes to higher emissions and reduced fuel economy. This can help to bring your emissions down to the level they should be when the injectors are clean. If your car’s failed its MOT on emissions or you’re worried that they’re too high, it could be due to building up in the fuel system, so using Redex could lower them back down. Please note: Redex Emissions Reducer is intended for older vehicles to help reduce emissions back down to the levels of the car when it was new.
