The 2008 Hyundai Elantra requires 4.2 quarts of SAE 5W-20 oil. Hyundai recommends using synthetic oil for better engine protection. There are two main types of oil: synthetic, which is designed in a lab to offer improved protection for your engine's components compared to conventional oil, and conventional oil. Synthetic oil also lasts longer, with oil changes needed every 7,500 miles instead of 3,500 to 5,000 miles with conventional oil. It's important to check your oil level at least once a month and inspect it for any debris or signs of burning that could potentially cause permanent engine damage.
In 2008, the Hyundai Elantra needs 4.0 liters of oil (equivalent to 4.23 US Quarts). To improve gas mileage, it's best to go with engine oil that has a viscosity rating of SAE 5W20 or 5W-30 (API SJ, SL / ILSAC GF-3, or better). If you can't find the recommended oil in your area, refer to the engine oil viscosity chart to pick the right alternative.
