The Hyundai Sonata comes equipped with an 18.5-gallon gas tank, and it's important to fill it with regular unleaded gasoline with an octane rating of 87 or higher. Avoid using E85 or diesel fuel in your vehicle as it can damage your fuel system and engine. I suggest using the highest octane fuel that fits your budget, as it will burn more thoroughly in the engine, reducing carbon buildup. Look for top-tier gas options in the market, which contain additives and detergents that can dissolve engine sludge, extending its lifespan and minimizing wear and tear.
