Improve emissions

Older diesel cars are prone to failing MOTs due to excessive exhaust gas readings but Liqui Moly says its Diesel Purge should fix this by cleaning the engine and the combustion chamber; dissolving deposits and improving exhaust gas values.

A leading engineer at the firm says: “To get the maximum effect, you can run the engine on pure treatment.” To do this the fuel lines in the engine compartment must be disconnected and the open pipes leading to the engines are placed in the Diesel Purge can.

The engine is started and takes its fuel directly from the can and getting a highly concentrated treatment. The engine should then be run at slightly increased RPM with full throttle a few times. The engine should then be stopped just before the can is empty.
