How many liters of engine oil does the Nissan Patrol V6 use?

If you truly care about your current vehicle and don't plan to replace it within ten years, it is recommended to change conventional oil every 5,000 kilometers and synthetic oil every 5,000-7,000 kilometers. Never consider early oil changes as wasteful. After five years, when comparing with similar vehicles, you'll notice significant differences in terms of power, fuel consumption, and maintenance costs. Below is relevant information about the functions of engine oil: Lubrication: The primary function of engine oil is to supply proper lubrication to the engine's pistons, bearings, and other components. Sealing: During the "power" stroke, engine oil prevents high-temperature and high-pressure gases in the combustion chamber from leaking into the crankcase through the gap between the piston and cylinder. Cooling: In a normally operating engine, the temperature at the top of the piston can reach as high as 300°C, but only 1/4 of this heat is effectively converted into kinetic energy to power the vehicle. The remaining 3/4 of the heat must be dissipated by the cooling system, exhaust system, and engine oil. Additionally, when the engine operates at high speeds, the high-speed moving parts generate intense heat due to friction. This heat must be absorbed by the engine oil flowing through the gaps between these components and then carried to the oil pan (oil sump) or oil cooler, where it is dissipated into the air. Rust prevention: Engine oil prevents corrosion of metal components. Cleaning: It filters out impurities and metal wear particles generated during engine operation through the oil filter, maintaining the cleanliness of the lubrication system.
