1. Gasoline (Petrol) Engines:
- Most Kia Avella models equipped with gasoline engines require unleaded regular gasoline with an octane rating of 91 or higher. You can use gasoline with an octane rating of 87 if it's specified as acceptable in your owner's manual.
2. Diesel Engines:
- If your Kia Avella has a diesel engine, you must use diesel fuel or biodiesel blends designed for diesel engines. Diesel engines do not run on gasoline.
It's essential to check your Kia Avella's owner's manual or consult with an authorized Kia dealer to verify the specific fuel requirements and recommendations for your vehicle. This will ensure proper engine performance and avoid potential issues related to using the wrong fuel.
