Round: 2
Load: 2 kg

What does the test show?
The friction test is to show the resistance of the oil film to tearing (strength of the oil film). The friction test is to simulate engine operation.
Metal parts of the engine during its operation can lead to scratches and scratches. The better the oil quality, the better it should protect the engine from scratches.
Each sample subjected to this test will certainly have some scratches (cavities). By measuring the sample, we will be able to check the depth of the groove.
