TiO2 nano- or microparticles to engine oil, its thermal conductivity increased by 57% and 23%, respectively. For example, for 0.1 wt.% sample, at first, 0.025 g of CuO nanoparticles was mixed with 25 g base oil inside the cup of the planetary ball mill, and then the ball mill worked based on the condition in Table 2.

The Group II-based engine oil had a thermal conductivity value within the typical range for engine oil, but was less dependent on temperature than the Group V-based oil. Overtime, engine oil degrades from heat, pressure, and the collection of debris.
