The Holts Redex Petrol System Cleaner is a simple part of a car maintenance routine which can increase fuel economy, improve the working life of your injectors and extend the life of your car. It’s like an exercise which keeps your car fit, pour a shot of Redex Petrol System Cleaner into the tank regularly to keep your car driving further.

During combustion, deposits build up on your fuel injectors and lead to an inefficient use of petrol. Redex stops this build up and cleans the injectors to save you petrol, and as the UK’s number one fuel additive we’ve been trusted by drivers for decades.

A regular shot of Redex, specially formulated for petrol engines, can put money back in your pocket and help you to pass your MOT by reducing your emissions.
