About Redex
Redex is the iconic UK fuel additive brand that has been helping drivers since 1922 - over 100 years of motoring heritage. Created in an era when petrol quality was poor and engines were more problematic, Redex became synonymous with engine care. In the 1950s and 60s, petrol station attendants would famously ask 'shot of Redex with the petrol?' as part of the fill-up routine. In 1973, Redex was acquired by Holts and joined the Holts Auto family of automotive products. Today, Redex remains the UK's market leader for fuel additives, continually innovating to meet the demands of modern vehicles. In 2015, the brand launched the Redex Petrol Injector, combining three products into one for maximum convenience. The modern Redex range includes Petrol System Cleaner (which also protects against E10 corrosion), Diesel System Cleaner, DPF Cleaner for diesel particulate filters, Super Fast Emissions Reducer, Lead Replacement for classic cars running on leaded petrol, and AdBlue. Redex has also expanded into fully synthetic engine oils for various vehicle specifications including Ford, BMW, VW, and Mercedes-Benz. Compare Redex prices at UK supermarkets on Grocefully.
