Oil friction test Petronas Syntium 3000 E 5W40
Round 3
Sample material: spring rod
What does the test show?
The friction test is intended to show the resistance of the oil film to tearing (the 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 and 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.

How does the test run?
A new sample is subjected to friction between metal and metal under a load of 1kg for a period of 2 minutes. Then the diameter of the sample is measured at its lowest point. Each new sample has a diameter of 3.00 from which it subtracts the diameters of the tested sample. If both dimensions are subtracted, we obtain a realistic measurement of the sample's wear and tear. The lower the result, the better.
Results: 0.42
