2004 Hyundai Elantra: What is the oil type and capacity?

The 2004 Hyundai Elantra takeS3.88 liters (4.1 quarts) of SAE 5W-30 engine oil. However, 5W-40 is a suitable replacement, if the other isn't available. A few popular recommendations for SAE 5W-30 are Castrol Edge, Kendall, and Amsoil. If You are high mileage driver, consider Valvoline High Mileage, Pennzoil Platinum, Mobil 1, and Castrol GTX. The owner's manual for the Elantra recommends changing the oil every 7,500 miles. However, if Your daily commutes are comprised of constant stop-and-go traffic at low speeds or if You live in a dusty environment, such as on a dirt road, Your service interval may need to be more frequent. Old or low oil can't properly keep moving components lubricated or assist in keeping the engine cool. The average cost to change this fluid in the 2004 Elantra is $110 to $130. Labor accounts for $50 to $60 of that amount.
