Abstract: An engine oil additive includes carbon nanotubes and boron nitride particulates dispersed within a fluid. The additive is configured to be mixed with a quantity of oil such that the quantity of oil has a concentration from 0.05 to 0.5 grams of carbon nanotubes and of boron nitride particulates per quart of oil to improve the lubricity of the oil. The additive improves the horsepower and torque of the engine while reducing fuel consumption. The carbon nanotubes have an -OH functionalized exterior surface. The carbon nanotubes have a diameter from 1 nanometer to 50 nanometers and have a length from 1 micron to 1000 microns. The boron nitride particulates are hex-boron nitride structures having an average size from 30 nanometers to 500 nanometers.
