Liqui Moly DI Jectron cleans direct injection fuel systems and reduces the risk of engine damage caused by Low-Speed ignition (LSPI). DI Jectron contains a unique combination of proven PEA technology and is the latest additive generation to achieve maximum cleaning performance in the combustion chamber, in and around the injector tip, and in the entire fuel system. This highly advanced product removes deposits that build up on injector tips and in turn, reduces the chance of LSPI engine damage. Regular use of DI Jectron maintains fuel efficiency, and performance and stops the formation of new deposits.
