No smoke reduces the emission of gases. Facilitates technical inspection. Reduces oil consumption. Reduces motor noise. Proven effectiveness.Perform the bubble test: 1. Invert the vial; 2. Watch the smoke stop bubble rise; 3. The BARDAL bubble rises very slowly and proves that the polymers contained in its formula are extremely dense, something that makes the product efficient.Excessive exhaust smoke is a sign of abnormally high engine oil entry into the combustion chambers. Thanks to its high viscosity formula, the product restores the sealing of the segments. Reduces the emission of polluting smoke, facilitates the passing of inspection for harmful gases, reduces oil consumption, reduces engine noise, does not clog the oil filter.How to use: With a warm engine, as a supplement or after pouring the oil, add ½ bottle to the motor oil crankcase. To repeat the treatment every 15,000 kilometers. Mixes with any type of oil. Compatible with catalytic converters and particulate filters. Recommended by the biggest constructors.
