The Liqui Moly DI Jectron Direct Injection Fuel System Cleaner is an advanced high-performance petrol fuel additive specifically developed for modern direct injection engines. Using proven PEA (Polyetheramine) cleaning technology combined with the latest generation additive package, DI Jectron delivers exceptional cleaning performance throughout the entire fuel system, including injector tips, combustion chambers, and fuel delivery components. This specialised cleaner effectively removes stubborn carbon deposits while preventing the formation of new build-up that can negatively affect fuel atomisation and engine efficiency. By maintaining clean injectors and fuel pathways, DI Jectron helps optimise engine performance, improve fuel combustion, and reduce exhaust emissions. Regular use also reduces the risk of low-speed pre-ignition (LSPI), a common issue in modern turbocharged direct injection petrol engines, helping to protect engine components from potential damage. Designed for preventative maintenance and performance restoration, Liqui Moly DI Jectron enhances drivability, supports smoother engine operation, and protects the entire fuel system against corrosion. It is safe for use in vehicles equipped with catalytic converters and petrol particulate filters, making it suitable for modern emission-controlled engines.
