BARDAHL 147023 – ENGINE TUNE-UP 355 ML

Bardahl Engine Tune-Up is Bardahl's engine cleaner that you pour into the sump together with the oil: it dissolves and removes gums, varnish and sludge built up in the lubrication circuit and on internal metal surfaces. It is intended for drivers and workshops who want to bring the engine back to full efficiency, on petrol and diesel engines and with any type of oil.

What it is for

According to Bardahl it is indicated when the engine shows poor lubrication, loss of performance and efficiency, malfunctioning hydraulic systems (such as tappets) or oil that degrades quickly. The typical causes listed by Bardahl are deposits and sludge in the engine, stuck or gummed piston rings, loss of compression and reduced clearances in hydraulic systems.
