The engine oil filler port is generally located on the left side of the engine, specifically the yellow circular component on the engine cylinder head. Below are related details about engine oil filling: 1. Purpose of adding engine oil: The engine is the heart of a vehicle, containing numerous metal surfaces that rub against each other during operation. These components move at high speeds under harsh conditions, with operating temperatures reaching 400°C to 600°C. Only qualified lubricating oil can reduce wear on engine parts and extend their service life under such severe operating conditions. 2. Function of the engine oil filler cap: It is opened when adding oil and tightly sealed when not in use to maintain proper sealing.
