What is the reason for the oil pump having no pressure?

[Leonard]

Oil pump has no pressure due to a damaged overflow valve. Below are the specific details related to fuel consumption: 1. Fuel consumption: The fuel consumption of large-displacement cars is as high as that of family cars. 2. Comparison: A fuel consumption of 6 liters per 100 kilometers, on the same route, a 1.6L car, the Octavia consumes 7 liters. Sports car drivers usually give much more throttle, consuming more fuel than street cars, resulting in higher fuel consumption. A liter-class sports car, during aggressive acceleration or high-speed runs, has fuel consumption comparable to the combined fuel consumption of a 3.0L car. 3. Fuel: Most cars use gasoline, so the energy from the fuel is the same. The relatively higher fuel consumption of the Octavia comes from high wind resistance, a compact structure leaving no room for fuel-saving technologies to be applied, and a design philosophy that emphasizes high-revving power extraction.
