Tecflow Engine Flush Tecflow Engine Flush is an oil system cleaner that cleans all engine oil-lubricated parts in the engine, preventing direct contamination of new oil after an oil change due to residual deposits. DESCRIPTION: Cleaning the oil system / engine block is not an unnecessary luxury, as is often claimed, and certainly not with newer engine types. Contamination can be very harmful, especially for cars with hydraulic tappets. Contamination can cause reduced oil pressure in the gallery that feeds the hydraulic tappets. The high-pressure chambers are then not fully filled, resulting in play between the cam and the top of the valve stem, which is clearly audible. Contamination can also lead to the ball no longer properly sealing the high-pressure chamber, causing the hydraulic tappets to tick. PROPERTIES: - cleans the oil scraper ring and frees stuck hydraulic tappets - prevents contamination of new oil by residual deposits - cleans the oil pump, pump screen, and overpressure valve - cleans the supply line to the camshaft - cleans all oil channels, ensuring optimal oil pressure - cleans accumulated dirt near the oil sensor - contains EP and anti-corrosion additives for extra protection - Cleans any catalytic converter This is the best you can get for your car!
