Redex Fuel System Cleaner for Petrol and Diesel Cars, 500ml, 4 Pack Sluggish throttle response and climbing fuel bills usually point to one silent culprit: gummed-up fuel injectors. Over thousands of miles, microscopic carbon deposits choke your engine's combustion chambers, stealing horsepower and wasting expensive fuel every time you hit the accelerator. UK Industry-Standard Deposit Removal Unproven generic additives fail to break down stubborn, baked-on lacquer inside modern high-pressure injectors. Formulated by the UK's leading fuel treatment specialist, Redex dissolves harsh combustion residue at the molecular level, restoring razor-sharp spray patterns and preventing costly mechanical maintenance down the road. Targeted Engine Maintenance Highlights Active Injector Purge: Sweeps away harmful carbon build-up to maximize fuel atomisation and restore lost engine responsiveness. E10 & E5 Fuel Stabilisation: Safe for use with modern petrol blends (including E10), as well as conventional diesel and hybrid powertrains. Emissions Reduction: Cleans internal fuel pathways to promote complete combustion, helping lower overall exhaust output before MOT checks. Calibrated Dose Bottle: Clear dosage markings on the side panel take all guessing out of treating average 50-litre fuel tanks.
