Where is the engine oil filler port located?

Automobile engine oil filler port is generally located on the left side of the engine. Classification of engine oil: Engine oil is divided into three categories: mineral oil, semi-synthetic oil, and full synthetic oil. The replacement cycles for these three types of oil also vary. Generally, mineral oil should be replaced every six months or 5,000 kilometers, semi-synthetic oil every six months or 7,500 kilometers, and full synthetic oil every six months or 10,000 kilometers. Precautions for adding engine oil: The quality of engine oil has a significant impact on the working environment of the engine. The engine operates in a high-temperature environment, continuously repeating mechanical friction movements. In this process, engine oil plays the roles of cooling, lubrication, and cleaning. Over time, the impurities in the engine oil increase, and its performance declines accordingly.
I remember once helping a friend add engine oil—he circled the car three times without finding the right spot. Actually, after opening the hood, it's the round plastic cap marked with an oil can symbol (often labeled 'OIL'). On most cars, the filler cap is located at the front top of the engine, near the edge of the engine cover. For German cars like Volkswagen, it's usually next to the intake manifold, while Japanese models like Toyota often place it closer to the windshield. Look for a cast iron or brass-colored cap. Don't confuse it with the coolant filler (which has a larger cap with a triangular warning symbol). If you can't find it, follow the dipstick downward—the filler is usually within 30 cm above it. When in doubt, check Chapter 7 of the manual; it always has a diagram.
