K2 engine flush is a development product based on highly effective, state-of-the-art additive technology. Highly effective, oil-soluble and oil-insoluble residues of all kinds are suspended and removed from the oil circuit when the oil is changed. The engine has been freed from deposits and dirt and the new oil has not been contaminated by old contamination and can therefore show its full performance. A 250 ml can is sufficient for up to 2.5 liters of oil capacity. Add K2 engine flush to the engine oil at operating temperature before changing the oil. After adding the engine, depending on the degree of contamination, approx. 10-15 mins let it run at idle. Then change the oil and filter. We have been selling car parts online since 2013. Since then, we have been constantly expanding our ran.
