Is Synthetic Engine Oil Suitable for Hyundai Elantra?
2 Answers
Hyundai Elantra is suitable for using synthetic engine oil. Below is relevant information about automotive engine oil: 1. Mineral Oil: Mineral oil is a commonly used lubricant in the market. It is derived from the useful substances separated during the petroleum refining process, such as gasoline and aviation fuel, with the remaining base oil further processed and extracted. 2. Semi-Synthetic Oil: Semi-synthetic oil is a product purified from mineral oil through hydrocracking technology, consisting of a 4:6 ratio blend of mineral oil and full synthetic oil. Its purity is very close to that of full synthetic oil. 3. Full Synthetic Oil: Full synthetic oil is a high-grade product among engine oils. It is made from ethylene and propylene dispersed from natural gas or crude oil gas, undergoing complex chemical reactions like polymerization and catalysis to form a lubricating fluid composed of large molecules.
I just picked up my Hyundai Elantra and specifically asked the 4S店 technician about engine oil during the first maintenance. The technician said that using full synthetic oil is quite suitable for the Elantra, especially for the new engines with CVVD technology. I've been using 5W-30 full synthetic oil for half a year, and the most noticeable difference is that the engine sound during cold starts is much smoother than before—no more coughing-like rattling noises when starting in cold weather. Additionally, the RPM is more stable when driving on the highway, and the fuel consumption display shows a drop of about 0.3L. However, the technician specifically warned that turbocharged models must use full synthetic oil; otherwise, it’s prone to coking under high temperatures. The oil change interval can be extended to 7,500 kilometers, but never skimp on costs and end up with counterfeit oil. Someone in our car owners’ group fell victim to this, and it cost over 6,000 yuan to repair the engine due to cylinder scoring.
