Types of Fuel Used in a Chevy Suburban

Leaded gasoline "Premium"

Differences between premium gasoline and regular gasoline

The main difference between premium gasoline and regular gasoline is the octane number. Premium gasoline has a higher octane number of 91, while regular gasoline has an octane number of 87. Premium gasoline's higher octane number means it is less likely to cause knocking or ringing in high-performance engines.

As a result, premium gasoline is widely used in sports cars and other high-performance vehicles. However, it is important to note that most vehicles, including the Chevy Suburban, do not require premium gasoline.

In fact, using premium gasoline in a car that doesn't need it can reduce fuel economy. Therefore, use regular unleaded gasoline unless your car specifically requires premium gasoline. This saves money at the pump and has no negative impact on your car.
