What type of engine oil is used for the Hyundai Elantra?
1 Answers
The Hyundai Elantra uses SM5W-20 original semi-synthetic engine oil. If you want to change the oil during later maintenance, you can choose fully synthetic oils from well-reputed brands such as Mobil, Shell, or Castrol. The official manual recommends 0W-20 oil. Considering China's temperature conditions, 5W20 or 5W30 oil can be used in most regions. 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, making cold starts smoother. The second number represents the kinematic viscosity of the oil at 100°C. A higher value means the oil can maintain viscosity 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 the Hyundai Elantra 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 and place an oil pan underneath to catch the old oil until it stops flowing. Start the engine and let it run for 30 seconds to allow the oil in the main oil passage to drain out; Use a specialized wrench to remove the oil filter; Apply oil to the oil seal of the new oil filter and tighten it clockwise by hand; Add new oil through the oil filler cap on the engine valve cover, usually filling about three-quarters of the oil container; Start the engine and let it run for 5 minutes, checking for leaks around the oil drain plug and oil filter. If leaks are found, repairs should be made; After stopping the engine, pull out the dipstick to check if the oil level is within the standard range.
