Should the Verna use 20 or 30 engine oil?

The Verna can use fully synthetic 20 engine oil. Engine oil change interval: Most engine oils abroad are changed at 10,000 kilometers, while domestic manufacturers in China generally advance the change interval to 7,500 kilometers or even 5,000 kilometers due to poor road conditions. However, in reality, as long as the oil color is clear, the oil level is not below the marked minimum level, and there are no special circumstances, the engine oil does not need to be changed so frequently. Functions of engine oil: Cooling and temperature reduction, sealing and leak prevention, cleaning, shock absorption and buffering, lubrication to reduce wear, rust and corrosion prevention, and component protection. Engine oil, also known as engine lubricating oil, is composed of base oil and additives. Base oil is the main component of lubricating oil, determining its basic properties, while additives can compensate for and improve the shortcomings of base oil performance.

I've been driving a Hyundai Verna for 5 years and have tried different engine oils. Currently using 5W-20 which works quite smoothly. When the car was new, the manual recommended 5W-20 or 0W-20 - these low-viscosity oils save fuel without extra effort, giving me an average commute fuel consumption of about 6L/100km. In hot summers, if I use 5W-30, the engine sound becomes slightly louder and fuel costs increase a bit, but the protection is decent. For cold winter starts, 0W grades are most suitable - don't cheap out by using high viscosity oils like 10W-40, or you'll get slow cold starts and component wear. Change oil regularly, check oil level and color every 5,000 km. Beginners should consult technicians at 4S shops - following the manual is safest, don't experiment blindly for peace of mind and safety.

Having been a car enthusiast for years and frequently assisting with maintenance, I recommend using low-viscosity oils like 5W-20 or 0W-20 for the Verna, as they are designed to reduce engine friction. The manual clearly states that viscosity selection depends on local climate: 5W-20 suffices for temperate zones, while 0W grades are preferable in colder regions to prevent startup difficulties. Higher viscosity oils like 5W-30 may perform better in extreme heat, though they generally offer poorer fuel efficiency and slightly higher consumption. During checks, monitor oil pressure – replace immediately if readings are low or contaminants are present. DIY oil changes are straightforward: prepare the correct filter and certified oil (avoid counterfeits), and adhere to service intervals to prolong engine life.

I drive long distances every day, and the Verna performs best with 5W-20, offering smooth acceleration and low noise on highways. The manual recommends prioritizing 20-grade oils, with 5W being suitable for most conditions. In extremely cold weather, 0W-20 ensures quicker cold starts, while 5W-30 provides better protection during heatwaves. Don’t overlook oil temperature monitoring—check oil levels when parked in high temperatures to prevent excessive thinning and part damage. Regular oil changes are crucial in maintenance; choosing the wrong viscosity affects power and fuel efficiency in the long run.
