For over 100 years, Redex Fuel Additives and fuel cleaners have been renowned for their effectiveness in keeping your engine clean and efficient. As E10 petrol was introduced to the forecourt, we developed the Redex Petrol System Cleaner to help protect against its corrosive effects.

Over the years, we’ve added Pre-MOT emissions reducers, lead replacement, and most recently engine oils to our range – all with the same great Redex quality our customers have always depended on.
