Castrol Techniclean™ SC 320 ( previously named Castrol Detergen™ System Cleaner 320) is an additive to clean oil systems.
Added to the oil before the oil change, Techniclean SC 320's dispersant additive package softens and removes sludge, lacquer formation, and resin- like deposits. The contaminants are then is kept in suspension and the particles are removed from the system with the oil drain.

Techniclean SC 320 has been designed for cleaning of oil circulation systems and oil reservoirs of engines, gears and hydraulic systems before oil change without the application of flushing oil or an intermediate oil change.
Further, it provides improvement of the cleaning properties of conventional flushing oils or low-viscosity oils used as system cleaners before the initial fill.

Cleans oil systems before the oil change.
Saves costs since flushing oil is not needed and manual cleaning is not required.
Dissolves sludge residues and deposits into very fine particles.
Keeps dissolved dirt particles in suspension.
Cleans machine components from oil residues.
Cleans systems before the initial fill or after assembly.
Allows longer service life of the new oil due to clean oil reservoirs.
Practically no effect on the viscosity of the oils in service.
