How many liters of engine oil should be added to the Highlander?
1 Answers
The Highlander should be filled with approximately 4.5L of engine oil, based on the dipstick's scale. Engine oil serves multiple functions such as lubrication, cleaning, cooling, sealing, wear reduction, rust prevention, and corrosion protection for the engine. Here are some additional details: 1. The engine is the heart of a car, containing many metal surfaces that move against each other. These components operate at high speeds, in harsh environments, and can reach temperatures between 400°C to 600°C. Under such severe conditions, only qualified lubricating oil can reduce wear on engine parts and extend their service life. 2. Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, providing new properties and playing a crucial role in the lubricating oil.
