Does Using Regular Fuel Instead of High-Octane Affect the Sonata’s Mileage in Pakistan?

Fuel quality varies widely in Pakistan, and not all owners use high-octane fuel due to cost. Does using regular petrol reduce the Sonatas fuel economy o r cause engine knock, especially in the 2.5L variant?

The Hyundai Sonata is designed to run on high-octane petrol. Using regular fuel may lead to:

Reduced Engine Efficiency: Lower octane fuels can cause knocking, leading to decreased engine performance and fuel economy.

Potential Engine Damage: Prolonged use of lower octane fuel can cause long-term damage to engine components.

Its advisable to use the recommended high-octane fuel to maintain optimal engine performance and fuel efficiency.
