Automotive treatment that deep-cleans diesel fuel systems and restores performance. Drivers fed up with poor economy and sluggish acceleration will welcome smoother starts and livelier throttle response. Is Wynn's Extreme Diesel System Cleaner the right single-treatment solution for your diesel or better left to workshop service?
⚡ At a Glance
- • Cleaning Power: Removes carbon, soot and injector deposits to improve fuel flow
- • Best for: Owners of diesel cars and vans seeing reduced fuel economy or rough running
- • Not ideal for: Petrol engines and vehicles without diesel injectors or DPF systems
Powerful single-treatment additive cleans fuel pump, injectors and intake valves. Also helps reduce emissions and supports turbo, EGR valve and DPF cleanliness.
Restored Fuel Delivery - with deposit-dissolving chemistry
Solvent action targets carbon and varnish in the fuel pump, diesel injectors and intake valves, breaking down stubborn residues. A single-treatment formulation is designed to circulate with one tank of fuel and contact key components.
Cleaner passages improve fuel atomisation and consistent fuel delivery. Expect steadier idling and more responsive throttle where injector blockage was present.
Improved Starting and Driveability - thanks to injector flow recovery
Clearing injector nozzles restores spray pattern and fuel metering, reducing misfires and hesitation during ignition. Restored atomisation promotes more complete combustion across operating conditions.
Cold starts become more reliable and rough idling is reduced, lowering strain on the battery and starter. Acceleration feels less sluggish after treatment.
Protects Exhaust Components - with preventative action on turbo, EGR and DPF
Cleaner combustion reduces soot and particulate formation that typically accumulates in turbochargers, EGR valves and diesel particulate filters. The formula helps limit carbon and soot build-up that cause blockages.
Reduced risk of DPF regeneration issues and stuck EGR valves keeps exhaust flow healthy. That lowers the likelihood of repair bills linked to soot-related failures.
