Wynns CV Oil System Flush is designed to dissolve varnish, deposits, and sludge throughout the entire oil circulation system. It prevents contamination of new engine oil by residues left behind and protects turbos by cleaning oil lines and obstructions. The flush keeps dissolved impurities in suspension, preventing their agglomeration and ensuring a cleaner oil change. This formulation is compatible with all engine types, including those using synthetic and mineral oils, and is safe for all engine components.
