Automobile Engineering

Engine oils work by lubricating moving parts; this action diminishes friction and tear, hence enabling the engine to run normally to prevent it from overheating and being damaged. Having the same functionality in lubrication of gears, transmission oils help keep gear shifts smooth, as well as protecting the transmission system from any damages such as general corrosion and tear related to wear and tear over time. Differential gears are lubricated by differential oils leading to efficient power transmission to wheels. Hydraulic and brake fluids are some examples of special purpose oils that are used for proper functioning of hydraulic and brake systems.
