What type of engine oil is suitable for the Verna?

[LaMaria]

For the Hyundai Verna, semi-synthetic engine oil is recommended. Below is the relevant information: 1. 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 act as a shock absorber. It is often referred to as the 'blood' of a car. 2. Engine oil consists of two main components: base oil and additives. The base oil is the primary component of lubricants, determining their fundamental properties, while additives compensate for and improve the shortcomings of the base oil, imparting new characteristics. Additives are an essential part of lubricants. 3. Synthetic oils are further divided into full synthetic and semi-synthetic. Lubricant base oils are mainly categorized into mineral base oils and synthetic base oils. Mineral base oils are widely used and account for a large proportion (about 95% or more), but certain applications require products formulated with synthetic base oils. 4. 10W-40 represents its SAE standard viscosity rating. This viscosity rating first indicates that the oil is multi-grade. The 'W' stands for WINTER, and the number before the 'W' indicates the oil's flow performance at low temperatures—the smaller the number, the better the starting performance in cold conditions. The number after the 'W' represents the oil's stability at high temperatures (i.e., its tendency to thin out)—the larger the number, the better the oil's high-temperature stability.
