How Much Engine Oil Should Be Added at One Time?

Engine oil should be filled slightly below the mark on the dipstick, avoiding overfilling. Each car model has a different oil capacity, so the amount of oil required varies. Therefore, it's essential to add oil appropriately based on the dipstick's markings. Methods for selecting engine oil: Engine oil selection should align with the engine's requirements. It's unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in high-performance engines. Multigrade oil is recommended due to its cost-effectiveness, longevity, and efficiency, providing better engine protection. If the engine is in good condition and the ambient temperature is low, using lower-viscosity oil helps maintain smooth oil flow. In high-temperature seasons or when the engine is severely worn, higher-viscosity oil is preferable as it aids in forming a protective oil film, reducing engine wear. Effects of improper oil levels: Overfilling oil increases crankshaft resistance, reducing engine output power. Excess oil may enter the combustion chamber, leading to oil burning, blue smoke, and increased fuel consumption. Insufficient oil accelerates wear on internal engine components, potentially causing engine damage. Therefore, maintaining oil levels within the specified range is crucial.
I've seen many cars, and the amount of oil to add isn't fixed. It mainly depends on your car's manual, usually a small booklet near the dashboard—check the engine capacity. For example, a small car might need a bit over 4 liters, while a large SUV could require around 6 liters. Don’t rely on guesswork; it’s best to use the dipstick for checking: add some oil, start the car for a few minutes, then stop and wait for the oil to flow back into the oil pan. Pull out the dipstick—if the oil level is between the two marks, it’s just right. Never exceed the upper limit, as it may cause oil burning or damage seals. Also, I make it a habit to regularly check the oil condition. If it turns black or has metal particles, change it immediately. Remember, oil is like blood—the right amount keeps the engine healthy.
As a first-time car owner, I was really nervous about my first oil change. I mainly relied on the owner's manual, which specified the exact amount like 4.5 liters, so I bought the appropriate quantity of oil bottles. It's recommended to get fully synthetic oil for better durability, then slowly pour it in while repeatedly checking with the dipstick until the oil level reaches the middle mark. Avoid overfilling or underfilling to prevent excessive oil consumption or engine overheating. If doing it in your home garage, lay down an old rag to catch any spills. The key is to take your time – once you get the hang of it as a beginner, it's actually quite convenient and saves money.
