Round 4
Temperature: 100°C (oil is heated to 100°C)
Bel Ray EXP 4T 10W40

What does the test show?
The more weights you manage to put on the machine until it stops, the stronger the oil film tested will be. The test examines the oil film's resistance to tearing.
The sample is measured with a micrometer - the lower the result with a given load (the gouge in the sample is smaller), the oil will give better protection to the engine.
The table will give the result of the gouge of the sample, the number of weights put on the machine, the temperature when the machine is stopped.
