How much engine oil should be added to the Nissan Sylphy Classic at one time?

For the Nissan Sylphy with a 1.6L engine, it is generally recommended to add about 3L of engine oil, while for the 1.8L engine, it is about 4L. This is because it is impossible to completely drain the old engine oil during an oil change. For example, adding 2.8L for a 1.6L engine will already be close to the upper limit of the oil level. However, the exact amount of engine oil to be added should be between the upper and lower marks on the dipstick, as this level is the optimal fluid level. Here is an introduction to adding engine oil: 1. Different engine models and displacements are designed with varying oil capacities, generally ranging from 3L to 10L. There is an oil dipstick on the outside of the engine, and the oil should be added appropriately, ideally to the middle mark on the dipstick. Adding too little can damage the engine, while adding too much can increase oil pressure, leading to lubrication issues due to increased pressure in the oil lines. 2. When the engine cylinder block contains too much oil, it creates unnecessary resistance for the crankshaft rotation, affecting power output and increasing fuel consumption. 3. Excessive oil entering the combustion chamber increases carbon deposits, which raises piston movement resistance and reduces engine power. 4. Environmental standards may not be met, worsening exhaust emissions and severely affecting the lifespan of the catalytic converter, potentially even damaging it directly. Oil leaks can also reduce the lifespan of oil seals and may lead to engine oil leaks.
I remember driving the Nissan Sunny Classic before, and during each oil change for maintenance, it usually required about 4 liters of oil, which is the standard amount including the replacement of the oil filter. When performing the operation, I would check the oil dipstick level when the engine was cold, keeping it between the min and max lines. If only topping up without replacing the filter, it might take around 3 liters or less. The key is to be careful not to overfill, as too much oil can increase internal engine pressure, cause oil foaming, affect lubrication efficiency, and reduce engine lifespan. On the other hand, too little oil can lead to increased component wear. I recommend checking the oil condition every 5,000 kilometers or so, using a reputable brand of 5W-30 viscosity oil for daily city driving—no need to go for premium products. Regular oil changes help maintain engine health, saving money and ensuring peace of mind.
