High Performance Engine Treatment is an additive, increasing compression and preventing engine wear. Properties: It extends the engine service life, prevents oxidation, friction and wear. It increases compression and improves the oil viscosity index, preventing early added oil thickening. It prevents accumulation of sludge and dirt. It keeps the lubrication system clean. It reduces oil consumption and emissions. It does not comprise hard particles. It is compatible with all types of motor oils. It does not damage catalytic convertors. Application: It is recommended for all types of gasoline and diesel cars, both new and relatively old ones. Instructions: Add it in the motor oil, preferably during or right after the oil change. Do not exceed the maximum level! One 500-ml bottle is enough for 4 - 6 liters of oil. Add it in the oil annually or each 5000 km.
