Redex Emissions Reducer is safe to use, and with specific products for diesel or petrol it can be used in all modern engines. It works by removing deposits that form on the fuel injectors. There are deposits which, if left uncleaned, inhibit engine efficiency and increase exhaust emissions.
While it’s safe to use in most diesel and petrol engines, Emissions Reducer is specifically designed for older cars whose emissions may be close to the passable limit on the MOT. If your car is more than five years old, we’d highly recommend using Emissions Reducer as a safe and effective way to ensure it’s running at its cleanest.
