Purpose and Specifications

LIQUI MOLY 1019 Motor Clean is a powerful engine oil additive that deeply cleans the inside of your gasoline or diesel engine before an oil change. It dissolves stubborn oil residues, sludge, and deposits, wrapping dirt particles so they flush out with the old oil. This lets your fresh oil work at peak efficiency for smoother running, less wear, better fuel economy, and lower emissions.

When to Use / Replace?

Use Motor Clean every oil change, especially if your engine has over 50,000 km, shows power loss, high oil use, or rough idling from buildup.
