As a driver, you arrive at the pump ready to fuel up with your usual premium or regular gas. You probably don’t realize there’s more to your fuel choice than meets the eye.
These pumps contain gas with different octane levels, each conveying what’s known as the knock resistance of the fuel. Engine knocking is an undesirable event where the air and fuel mixture ignites on its own without the spark. If this occurs in your engine, you may feel a decrease in engine performance and other negative effects.
The octane ratings translate to the names we see at the pump (premium and regular), and understanding them helps you know what’s best for your car.
Check out our video below to learn why some cars require higher octane ratings than others.
