Hyundai Elantra 2017 Automatic Gasoline mileage: 300 KM or more Peace be upon you, I am announcing the Elantra 2017. The car is not without some bodywork. However, the engine is fully guaranteed, and the oil is changed every 4000 kilometers, and the green coolant. All consumable parts have been replaced with new, original ones, and I have gone through it thoroughly regarding consumable parts.
