What brand is the original engine oil for Beijing Hyundai?

[Pat]

The original engine oil brand for Beijing Hyundai is Mobis. For later maintenance and oil changes, options include ordinary Great Wall 5W20, South Korean SK's 5W30, and Shell's premium engine oil. The original API-SM/GF-4-SAE-5W-20 engine oil for Beijing Hyundai needs to be replaced every 5,000 kilometers. The Beijing Hyundai Tucson is equipped with a 1.6 turbocharged engine, which requires 5W-30 full synthetic engine oil for maintenance. The Hyundai 4S directly supplies the original premium gasoline engine oil A5, 5W-30 (4L pack), suitable for the entire range of Langdong, Mistra, Elantra, IX35, Tucson, Verna, Santa Fe, and Sonata. The viscosity of engine oil changes with temperature, so special attention is needed to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity, with 5W representing the ability to 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 latter number represents the kinematic viscosity of the oil at 100°C, with higher values indicating better viscosity retention at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The method for changing engine oil in Beijing Hyundai vehicles is as follows: Wait for the engine temperature to drop, allowing the oil to flow back into the oil pan; Use a wrench to loosen the oil drain plug, catching the old oil in a pan until no more oil flows. Start the engine for 30 seconds to allow the oil in the main oil passage to drain out; Use a special wrench to remove the oil filter; apply oil to the seal of the new oil filter and tighten it clockwise by hand; Add the new engine oil through the filler cap on the engine valve cover, generally filling up to three-quarters of the bottle; Start the engine and let it run for 5 minutes, checking for 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 to check that the engine oil level is within the standard range.
