Overview
Nulon 300ml Oil System Cleaner is designed to flush sludge and varnish from engines, ensuring cleaner oil during oil changes and maintaining engine performance.
This oil system cleaner effectively removes damaging deposits from your engine, keeping new oil cleaner for longer. It is safe for use in all engine types and assists in freeing up sticky valve lifters, while also ensuring that the oil strainer and pick-up remain clean. By using this product, oil can stay in engines longer and perform more effectively. For optimal results, add one bottle for up to 6L of old engine oil before an oil change, allowing the engine to idle for 10-15 minutes before draining the warm oil.
