What is the oil specification for the Hyundai Elantra?
2 Answers
Modern Elantra uses 5W-30 specification engine oil. The relevant introduction to engine oil is as follows: 1. Composition of engine oil: Engine oil consists of base oil and additives. Base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of base oil, imparting new performance characteristics, making them an important part of lubricating oil. 2. Classification of engine oil: (1) Winter oil: The SAE viscosity classification for winter oils includes grades such as 0W, 5W, 10W, 15W, 20W, and 25W. The symbol 'W' stands for winter, and the smaller the number before 'W', the lower the low-temperature viscosity, the better the low-temperature fluidity, and the lower the applicable minimum temperature. (2) Summer oil: The SAE viscosity classification for summer oils includes grades such as 20, 30, 40, and 50. The larger the number, the higher the viscosity and the higher the applicable maximum temperature. (3) All-season oil: The SAE viscosity classification for all-season oils includes grades such as 5W-20, 5W-30, 5W-40, 5W-50, 10W-20, 10W-30, 10W-40, 10W-50, 15W-20, 15W-30, 15W-40, 15W-50, 20W-20, 20W-30, 20W-40, and 20W-50. The smaller the number representing the winter part (indicating a lower applicable minimum temperature), and the larger the number representing the summer part (indicating a higher applicable maximum temperature), the wider the applicable temperature range.
I've been driving a Hyundai Elantra for several years. This model uses 5W-20 or 5W-30 synthetic oil, and the specific grade depends on your car's production year. Mine is a 2018 model, and the manual specifies API SM grade 5W-20 oil. Sticking to this specification has kept my car running smoothly - quick cold starts in winter and minimal engine wear during summer heat. I change the oil every 5,000 km or 6 months, and since adopting this routine, I've noticed slightly improved fuel efficiency. Never use higher viscosity oil like 10W-40, as it may overload the lubrication system and affect acceleration. If unsure, check your manual at a repair shop or consult the dealership - they'll know the latest recommendations. Regular dipstick checks are crucial to prevent engine damage from low oil levels.
