Note 2: After adding 9.5% of a viscosity index improver to the HVIH5 base oil, its shear stability index was measured.
Note 3: After adding 5.2% of a viscosity index improver to HVIH5 base oil, the percentage reduction in viscosity at 40°C was measured.
Note 4: The pour point was determined after adding 9.5% of a viscosity index improver to the HVIH5 base oil.
