How much engine oil should be added to a domestic Ninja?

A domestic Ninja motorcycle requires approximately 2-4 liters of engine oil. Precautions for adding engine oil to motorcycles: Do not overfill the engine oil: Overfilling can cause the oil to enter the combustion chamber during engine operation, or even spray out from the exhaust pipe. This leads to unburned oil forming large amounts of carbon deposits and gum deposits on the piston top, valve seats, and valve oil seals, accelerating mechanical wear and potentially causing premature damage to piston rings, pistons, and camshafts. Therefore, the oil level should be strictly controlled between the upper and lower marks on the dipstick. Do not mix old and new engine oil: Old oil contains a large amount of metal shavings, gum, and oxides. Mixing it with new oil reduces the effectiveness and lifespan of the new oil and can clog oil passages and cause component wear. Therefore, never mix old and new engine oil. Clean the engine before adding new oil: Long-term engine operation can lead to metal shavings depositing inside the engine, clogging the oil filter screen, oil pump, and oil passages. Before adding new oil, warm up the engine for 5 minutes, drain the old oil, add 1 liter of diesel or kerosene, let the engine idle for 3 minutes, drain the diesel, then add a small amount of new oil to rinse out any remaining diesel inside the engine before finally adding the new oil. This process helps flush out metal shavings and gum, ensuring clear oil passages.
I've been riding a domestic Ninja motorcycle for six or seven years. This thing usually has an oil capacity of around 1.8 liters, which is pretty common. Every time I change the oil, I first add 1.6 liters, start the engine and let it run for a few minutes, then turn it off and check the dipstick level, slowly topping it up to the middle mark. Don't add too much as it can easily cause the engine to overheat or leak oil, and too little won't lubricate well, damaging the engine. When choosing oil, pay attention to the viscosity; use a 10W-40 SJ grade from a reputable brand, and don't skimp by buying counterfeit products. With better maintenance, it rides much smoother, performs more stably, and lasts longer. Change the oil regularly every 3,000 kilometers, don't wait until the oil turns black and thick to deal with it to avoid malfunctions. Usually, just a simple check of the oil level can save you from major repair costs.
