  • compositions CL2 and CL3 were formulated so as to have a kinematic viscosity at 100° C. of approximately 7.5 mm 2 /s, these compositions are described in table 3 below.
  • the base oil and the additives are identical to those of compositions CL2 and CL3.
  • compositions according to the invention have a good Brookfield viscosity, improved compared to the reference CC1.
  • Shear stability is excellent. It can be seen that the solution of the invention, although more viscous, shears less than viscobase 11-522® during this test, despite the fact that the PAGs tested are more viscous than viscobase 11-522® .

  • the lubricating compositions according to the invention CL4 and CL5 make it possible to lower the coefficient of traction, the reproducibility of the test being of the order of 3%.
  • This reduction in the coefficient of traction is particularly advantageous in that it leads to an increase in the gain in Eco fuel.
  • the test is carried out using a Hyundai L13-B engine, whose power is 81 kW at 5,500 rpm, driven by an electric generator making it possible to impose a speed of rotation between 650 and 5,000 rpm while a torque sensor measures the frictional torque generated by the movement of the parts in the engine.
  • the friction torque induced by the test lubricant is compared for each speed and each temperature with the torque induced by the reference lubricating composition (SAE 0W8), here CC4.
  • the rpm ranges, the rpm variation and the temperature have been chosen to cover, in the most representative way possible, the points of the NEDC-certified cycle.
  • the gain in friction is evaluated for each lubricating composition (CL) as a function of the temperature and the speed of the engine and in comparison with the friction of the reference lubricating composition.
  • compositions according to the invention make it possible to increase the Fuel Eco, unlike the compositions not comprising any PAG according to the invention.
