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

The domestic Ninja requires approximately 2L of engine oil. Generally, mineral oil is sufficient for the domestic Ninja. If you prefer a higher quality option, semi-synthetic oil is more than adequate; there's no need for fully synthetic oil. Hazards of overfilling oil: Oil leakage can easily cause fires. The oil at gas stations is stored underground where temperatures are lower, especially during hot summer days. Due to thermal expansion, if the oil is overfilled, it may overflow from the vent holes. Aside from causing waste, if the spilled oil encounters an open flame (such as a cigarette butt), it can easily lead to a fire or even an explosion. Precautions when refueling: Avoid waiting until the fuel light comes on before refueling. Try to avoid refueling immediately after the gas station has just received a fuel delivery. It's best to refuel in the early morning or evening when temperatures are lower than during the day, as the oil density is higher during these times.
I think for the domestic small ninja motorcycle, the amount of engine oil to add mainly depends on the specific model and displacement. For example, the common 250cc version generally requires about 1 to 1.2 liters of oil. But the best way is to refer to the owner's manual, as it specifies the exact capacity designed for your engine. If the manual is lost, try checking with the dipstick: park the bike on level ground, let it warm up and then turn it off for a few minutes, pull out the dipstick, wipe it clean, reinsert it, then remove it to see if the oil mark is between the min and max lines—that’s the right level. Incorrect oil levels can damage the engine: too little increases friction and noise, while too much causes excessive pressure and oil burning, leading to white smoke. Regularly checking the oil level is key to daily maintenance. I recommend paying attention to the amount every time you change the oil, especially in summer when high temperatures cause the oil to heat up quickly—insufficient oil can easily lead to overheating. Remember to use all-season 10W-40 or a similar grade of oil, and don’t skimp by buying counterfeit products, as they accelerate part wear. It’s best to do this when the engine is cold to avoid burns—safety first.
