What brand of engine oil is best for the Verna?

[DiOlivia]

The Hyundai Verna uses Beijing Hyundai's original engine oil with a grade of 5W-20. If you want to change the oil during later maintenance, you can choose engine oils from brands such as Shell, Mobil, and Castrol. It is recommended to use fully synthetic oil for the Verna. Other recommended options include Shell Helix Ultra 5W30, which should be changed every 10,000 kilometers, and Mobil 1 Gold 5W30, which should also be changed around every 10,000 kilometers. For semi-synthetic oil, Shell Helix Blue 5W30 is the top choice, with an oil change interval of around 7,500 kilometers, followed by Mobil 1 Silver 5W30, which should be changed between 5,000 to 7,500 kilometers. Engine oils with grades of 5W-20 and 5W30 can both be used. The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, resulting in smoother cold starts for the car. The second number represents the kinematic viscosity of the oil at 100°C. A higher value means the oil can maintain its viscosity index better at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing the engine oil in a Hyundai Verna is as follows: Wait for the engine temperature to cool down, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug and place an oil pan to catch the old oil until no more oil flows out. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain; Use a specialized wrench to remove the oil filter; Apply engine oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the oil filler cap on the engine valve cover, usually filling about three-quarters of the bottle; Start the engine and let it run for 5 minutes, then check for oil leaks around the oil drain plug and oil filter. If any leaks are found, perform necessary repairs; After stopping the engine, pull out the oil dipstick and check that the engine oil level is within the standard range.
