The friction test is to show the resistance of the oil film to tearing (strength of the oil film). Metal elements in the engine during its operation (friction e.g. pistons) can lead to scratches and scratches. The better the quality of the oil, the better it should protect the engine from scratches. #motul7100 #motul4T #motul10W50 How does the test run?
