Problem: Turbocharger wear and tear
Solution: Liqui Moly’s Turbocharger Additive
Assessment: Due to their extreme engine speeds, correct lubrication is crucial for turbochargers. But this is precisely what is lacking when a turbocharger is replaced or re-installed after repair. Here, there is a particularly high risk of wear and tear as well as damage. But that’s easy to prevent. The turbocharger additive made by German oil and additive specialist Liqui Moly protects this sensitive piece of engineering when it is put into operation for the first time.
When a new turbocharger is installed or the old one is repaired, the bearings are dry. If the engine is started in this state and the turbocharger runs for the first time, the engine oil has not yet lubricated all the bearings. “Several 100,000 revolutions per minute without sufficient lubrication – that’s bound to impact on the material,” says Harry Hartkorn, Head of Application Technology with Liqui Moly. This not only causes a massive increase in wear and tear: it can also result in preliminary damage that drastically shortens the service life of the turbocharger.
The Liqui Moly Turbocharger Additive is designed to prevent this. The combination of active agents in the tube includes a high proportion of the solid lubricant MoS2. This MoS2 sticks to the metal surfaces of the bearings, ensuring lubrication the first time the turbocharger runs. This prevents failure while at the same time increasing the turbocharger’s lifetime.
