How many milliliters of engine oil should be added to the UY125?
2 Answers
The UY125 requires adding 600~650ML of engine oil as per the instruction manual. Here is some related information about engine oil: Function: Engine oil, also known as engine lubricant (English name: Engine-oil), with a density of approximately 0.91×10³ (kg/m³), serves to lubricate and reduce friction, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption for the engine. Composition: Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, giving it certain new properties, making them an important part of lubricating oil.
I've been running an auto repair shop for many years and have changed the oil for many UY125 models. The standard oil capacity is around 1000ml, but don’t be too rigid in actual practice. After draining the old oil, I recommend pouring in 900ml of fresh oil first, then starting the engine and letting it circulate for half a minute before shutting it off and waiting a few minutes. Checking the dipstick is crucial: wipe it clean, reinsert it, and pull it out again—the oil level should be between the two marked lines. If it’s below the lower mark, add a small amount, adjusting by 50ml each time. Overfilling can cause foaming and reduce lubrication efficiency, while underfilling accelerates wear. Remember to use good-quality mineral or semi-synthetic oil and change it every 2000km. Don’t blindly follow the standard; maintaining a habit of checking the dipstick can extend engine life. In cold weather, when the oil viscosity is higher, reducing the amount slightly is also safe. For tools, having a measuring cup and funnel on hand makes the job easier and avoids spills.
