What is the oil capacity of a 2010 Hyundai Elantra?

The 2003 Hyundai Elantra with a 2.0 L i-4 engine requires 4.2 quarts of oil with a filter, according to the manufacturer’s specifications. It is recommended to use SAE 5w-30 full synthetic oil for optimal performance. To maintain peak engine performance, it's advised to change the oil and filter every 3000 - 5000 miles. Neglecting this maintenance can cause the oil's viscosity to decrease, leading to inadequate lubrication of vital engine components like pistons and cylinders. Oil prices typically range from $5 to $10 per quart, depending on whether it is conventional or synthetic and the brand/quality chosen. When replacing the oil, be sure to also replace the oil filter. Regular oil changes are crucial to ensure the vehicle operates smoothly, which is why there is an oil light indicator in the car to remind you.
