Automotive fuel additive that restores injection strength and cleans EGR, DPF, turbo and catalytic systems, Bardahl Diesel Engine Cleaner promises a more efficient-running diesel. Peace of mind for drivers wanting smoother acceleration and lower fuel use. Is this the right maintenance step for older or high-mileage diesels?
⚡ At a Glance
- • Cleaning Performance: Restores injection strength and removes deposits from injectors, EGR, DPF and turbo
- • Best for: Owners of diesel cars and vans aiming to improve injector response and engine economy
- • Not ideal for: Engines that need mechanical repair or parts replacement rather than chemical cleaning
A 5-in-1 diesel system cleaner in a 500ml format targeting injectors, injection pump, turbocharger, DPF, outlet valves and catalyst. Designed to restore injection strength while helping to reduce fuel consumption and limit AGR valve dirt.
Restored injector performance – thanks to targeted injector and pump cleaning
Formula restores injection strength of injectors and cleans and protects the injection system, covering injectors and the injection pump. Concentrated agents remove deposit build-up that can blunt spray patterns and reduce efficiency.
Improved throttle response and more consistent combustion, resulting in smoother running and a more immediate engine response.
Cleaner exhaust and forced-induction components – with DPF, turbo and valve action
Cleans turbocharger, particulate filter (DPF), outlet valves and catalyst without dismantling and limits AGR valve dirt. Active ingredients target soot and carbon in exhaust-related components.
Helps reduce soot accumulation across exhaust systems and supports more reliable DPF and turbo performance during normal use.
Better economy and performance – with system-wide deposit reduction
Removing deposits across injection and exhaust systems reduces combustion inefficiencies and helps restore designed engine operation. The 5-in-1 approach treats multiple areas in a single application.
Owners can expect lower fuel consumption and a livelier engine feel after treatment, particularly on higher-mileage vehicles suffering deposit build-up.
