Compatible with all commercial engine oils and catalytic converters, the formula isolates solid particles and liquid impurities so they can be removed during the drain-and-fill service. Using the flush before replacing oil and filter helps restore smoother oil flow and supports the oil’s lubricating function without harming seals or engine materials.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this engine flush work during an oil service?\u003c\/h3\u003e\n\u003cp\u003eThe product is added to the existing engine oil and left to circulate while the engine idles for a short interval. Solvent and detergent ingredients break down deposits and suspend them in the oil so they exit with the drained fluid.
