How many milliliters of engine oil should be added to the UY125?

UY125 is equipped with Suzuki's Super Core EFI engine. According to the structure of this engine, the required amount of lubricating oil is 650ml. The following is extended content: The lubricating oil should be added in the appropriate amount: If there is too much lubricating oil in the engine, it may lead to increased engine resistance and reduced power output. In severe cases, it can even cause blue smoke from the exhaust pipe, creating the illusion of burning oil. Therefore, it is essential to add the correct amount of lubricating oil. Notes: The size of the engine casing and design standards vary for each engine, so the required amount of lubricating oil differs. For small-displacement models, one bottle of lubricating oil is sufficient, while medium to large-displacement models require two to four bottles. Therefore, it is crucial to understand the exact amount of lubricating oil your engine requires. Only then can vehicle maintenance serve its intended purpose; otherwise, it may lead to negative effects.
I remember clearly the last time I changed the oil myself. For the UY125, 650ml is sufficient if you're not replacing the oil filter. If you do replace the filter, you'll need around 950ml. However, when actually adding the oil, pay attention to the dipstick marks—the oil level should be between the upper and lower limits when the engine is cold. Many beginners make a common mistake—pouring in too much oil, which can actually damage the engine. I recommend first-timers buy two 1L bottles of oil; any leftover can be saved for top-ups next time, saving you an extra trip. After adding the oil, remember to let the engine idle for a few minutes before checking the dipstick again—this trick is particularly useful.
Having worked on motorcycles for over a decade, I've handled many UY125 models. The key to an oil change lies in precision. The standard is 650ml without replacing the filter and 950ml with a filter replacement. However, people often overlook checking areas like the chain oil seals. If you've removed the transmission cover, you might miss about 20ml. Personally, I prefer having the owner prepare 700ml of oil. Start by pouring in 600ml, run the engine for a few minutes, then turn it off and check the dipstick. If it's not enough, add small amounts multiple times. Don't throw away the remaining oil; it can be used for a follow-up check after about 300 kilometers. Remember, measuring on a cold, level surface is the most accurate—using the side stand can lead to significant discrepancies.
As a female rider, I dread complicated operations, but changing oil is super easy. My UY125 manual specifies 650ml of oil, but there are three practical tips: 1) Wait an extra five minutes when draining old oil to ensure it's completely dripped out; 2) Don't fully empty the new oil bottle—about 10ml will remain; 3) After refilling, run the engine for two minutes before shutting it off to recheck the level. Once I lazily added only 600ml, and the oil warning light flashed during a long ride—now I strictly follow the 650ml standard. Beginners should use a graduated measuring cup—far more reliable than guessing.
