WHAT IS THE CAUSE OF OIL LACKING IN THE ENGINE?

Your engine may leak oil due to a poorly installed or damaged oil filter, a cracked engine oil pan that struck a curb or a rock, or degraded seals allowing oil to seep out, such as the rear main seal or the valve cover gasket.

The main reason is the technology used in the engine. In new technology engines, the metals are designed in a way that provides high-performance, which leads to oil loss. In addition, not using oil with the appropriate viscosity and correct performance for the vehicle and operating at an excessive speed can cause oil reduction in the engine.
