The main difference between gasoline for cars is the octane rating. Octane rating is a measure of a fuel’s ability to resist “knocking” or “pinging” during combustion, caused by the air/fuel mixture detonating prematurely in the engine. The higher the octane number, the greater the fuel’s resistance to knocking or pinging.

1. Regular gasoline: This type of gasoline has an octane rating of 87, and is commonly known as “87 octane” or “unleaded gasoline”. It is the most widely available and the least expensive type of gasoline. It is suitable for most cars, but not recommended for high-performance engines.
2. Mid-grade gasoline: This type of gasoline has an octane rating of 89, and is commonly known as “89 octane” or “plus gasoline”. It is more expensive than regular gasoline, but less expensive than premium gasoline. It is suitable for cars that require a higher octane gasoline, but not necessary for most cars.
3. Premium gasoline: This type of gasoline has an octane rating of 91, 92 or 93, and is commonly known as “91 octane”, “92 octane” or “93 octane” or “super gasoline”. It is the most expensive type of gasoline and is typically used in high-performance and luxury vehicles.
4. Diesel: Diesel fuel is a type of fuel that is used in diesel engines. It is different from gasoline in that it is denser, has a higher energy content and is less flammable. It is used in cars, trucks, buses, and other heavy-duty vehicles.

It is important to note that using a higher octane fuel than is recommended for your vehicle will not provide any benefit, and may actually decrease performance and increase fuel consumption. Always consult the owner’s manual or consult with Trinity AutoWorx to determine the appropriate fuel for your vehicle.
